Detailed ways

The hinge shown in Figures 1 to 6 comprises a housing (1) which is pivotally connected to a fixing device (2). The housing (1) includes a screw plate (3) for fastening to the edge of the door (not shown). Linkage means (4) pivotally connects the housing (1) to an arm (5) extending from the fixing means (2). A resilient rod (6) extends tangentially to the shuttle body (7) for providing the stopping function as described below. The fastening device (2) comprises a first fastening plate (8) arranged to be screwed to a wall, door frame or other supporting structure, while the second fastening plate (9) is mounted on the second fastening plate by, for example Screws (25, 26) in elongated slots in (9) are adjustably fastened to the first fixing plate (8). Rotation of the hinge from the closed position to the open position causes the shuttle body (7) to slide forward in the housing (1).

The damping mechanism is provided by forced circulation of hydraulic fluid within the housing (1 ) by reciprocating movement of the shuttle (7) in a cylindrical hole (27) provided in the housing. The shuttle body comprises a proximal end (10) located towards the hinge axis and a distal end (11) located away from the hinge axis. An axially extending rod forms a cylindrical member (12) extending between the proximal and distal ends. A baffle (13) fastened to the surface of the hole (27) is fixed to the housing and slidably accommodates the member (12). The baffle (13) has an axial hole in which the member (12) can slide during operation of the damping mechanism. The inner surface of the bore (27) in the housing provides first (16) and second (17) chambers in which hydraulic fluid is provided. The chambers are connected by a passage including a one-way ball valve (21) arranged so that fluid can flow from the second chamber as the shuttle moves downward during the hinge opening as shown in Figure 4. (17) flows to the first chamber (16), so hydraulic fluid flows freely from the second chamber (17) to the first chamber (16) during opening of the hinge. Closure of the one-way valve (21) prevents backflow of fluid during closure of the hinge.

An axial channel (15) extends in the longitudinal direction of the member (12). The branch of the channel communicates with the first chamber (16) and the second chamber (17), allowing fluid to flow back. The flow rate of the fluid will be limited by the narrow cross-sectional area of the channel (15). In this way, the closing of the hinge is dampened, preventing the door to which the hinge is attached from slamming shut.

Additional channels (18) and (19) connect these chambers (16) and (17) via an adjustable valve (20).

The outlet (28) of the channel (18) communicates with the second chamber (17) so that as the shuttle moves to the hinged open position, fluid is forced through the adjustable valve (20) and channel (18) . The flow from the valve (20) back to the outlet (29) through the channel (19) can be controlled by adjusting the screw valve (20). Flows from the outlet (29) into the first chamber (16).

Another passage (22) with an opening to the first chamber (16) is located proximal the inlet (29) to provide an additional passage for oil to flow during the initial phase of closure of the hinge. Setting this screw (24) can adjust the flow through channel (22). Thus, differential damping is achieved depending on the proximity of the hinge to the fully closed position.

Figures 7 to 10 show another hinge according to the invention. This hinge has a combined damping and closing function. The housing (31) is fastened to the fixing means (32) by means of pivots and linkages as used for the previous embodiments. A screw plate (33) is used to allow the housing to be fastened to the edge of the door. The damping shuttle (37) is connected to the linkage (34) and arm (35) in the same manner as for the previous embodiment. A resilient rod (36) engages an annular groove in the shuttle body (37) to provide a stop function when the hinge is in the vertical open position. The fixing device (32) comprises a first fixing plate (38) arranged to be screwed to a wall or door frame, and a second adjustable fixing plate (39) to be screwed to the second fixing plate. A fixing plate, the screws are installed in the elongated screw holes to facilitate adjustment during installation.

The closing mechanism comprises linkage means (40) to be fastened to an arm (41) extending from the securing means (32). In the sectional view of section E-E of Fig. 10, this closing mechanism is shown. A spring (42) mounted to the linkage (40) extends between a spring seat (43) and the panel (44) such that the spring is compressed as the hinge opens. Loosening the hinge allows the spring (42) to exert a closing force, urging the hinge towards the closed position.

The configuration of the damping mechanism is the same as for the embodiment shown in Figures 1-6.

Figures 11 to 13 show another embodiment in which a single damping mechanism (53) similar to that shown in Figures 1 to 6 is located within the housing (50), between the two closing mechanisms (54, 55). The respective structures of these closing mechanisms are the same as those shown in the present embodiment.

Figures 14 and 15 show the fixing plates (8, 9) as shown in Figures 1 to 6 . During installation, the first fixing plate (8) is fastened to a wall, door frame or other supporting structure. The second fixing plate (9) is loosely connected to the first fixing plate (8) by means of screws (25, 26). The apertures (60, 61) are transversely elongated so that the plate (9) can be rotated around a central screw (62) located in the center of the second fixing plate. This allows the plate (9) to rotate about the screw (62). The screw (62) has an eccentric projection (63) arranged so that by means of an Allen key inserted into the socket (64), rotation of the screw (62) moves the plate (9) towards the door frame Lateral, medial or lateral. When the lateral and angular position of the plate (9) is correct, the plates (8) and (9) are fastened together by tightening the screws (25, 26).

Figures 16 and 17 show another embodiment where the vertical angular orientation of the plate (9) relative to the plate (8) can be adjusted using a lock nut (65) so that the separation between the plates can be controlled.

Figure 18 is a cross-section of the damping member with an adjustable collar with a threaded hole engaged on the externally threaded portion (67) of the proximal portion of the shuttle body (70). Set screw (71 ) can be loosened to allow rotation of collar (66) to advance notch (68) proximally or distally. A resilient member (69) corresponds to member (6) of Figures 1 to 6, the engagement of which provides a stop allowing the hinge to remain in a selected open position.

19 to 26 show another embodiment of the present invention. This hinge is configured for use with a notched arrangement. The housing (80) has a screw-fixed plate (81) and a pair of bent arms (82) attached to the fixed plate (84) by pivot pins (83). This fixed plate (84) is fastened to the shuttle body (85) by means of attachment means (86).

The shuttle (85) is mounted in a cylindrical bore (87) of the housing (80) with a distally extending axial member (88) which passes through an aperture in a fixed barrier (89). The baffle is fastened to the housing (80) by pins (90).

The cavity between the axial member (88) and the housing bore (87) forms a first cavity (91) proximal to the baffle (89) and a second cavity (91) distal to the baffle (89). Two chambers (92). The volume between the end (93) of the shuttle and the proximal surface of the baffle (89) defines the size of the first cavity (91). A pair of longitudinally extending channels (94, 95) extend distally through the member (88). The channel (94) has a branch (97) which communicates with the first chamber (91). The channel (95) has a branch (98) which also communicates with the chamber (91). The channel (94, 97) has a larger cross-section than the channel (95, 98). A one-way ball valve (96) is located in passage (94), conveniently at the rear end of member (88). The ball valve (96) is used to prevent hydraulic fluid from flowing through the passage (94) as the hinge moves to the closed position shown in FIG. 21 .

Figure 23 shows this corresponding arrangement in the open position.

A pair of adjustable screws (99, 100) (see Fig. 24 section B-B) allow adjustment of the maximum velocity of fluid flow through the channel (94, 95) to fine-tune the damping of the hinge.

A pair of resilient springs or flexible rods (101) are arranged to engage annular notches (102) in the proximal end of the shuttle body (85) when the hinge reaches the fully open position as shown in Figure 23 . This is to provide a convenient stop arrangement to hold the door in the open position.

27-36 show another hinge according to the present invention. The hinge has a soft closing function. The hinge comprises a housing (110) which is pivotally connected to a fixing means (111). The housing includes a screw plate (112) for securing to the edge of the door (not shown). Linking means (113) connect the housing to arms (114) extending from a plate (115) which is fastened to the fixing means (111) in the same manner as described with reference to the previous figures. The fixed plate (115) is adjustably fastened to the fixture (111) by means of screws (116) located in elongated slots in the plate (115) to allow for align. Additional screws allow for vertical adjustment of the plate (115).

The damping mechanism is provided by forced circulation of hydraulic fluid within the housing (110) by reciprocating movement of the shuttle within a housing bore provided within the housing. The shuttle body comprises a proximal end positioned towards the hinge axis and a distal end (11) positioned away from the hinge axis. An axially extending rod (120) extends between the proximal and distal ends. A baffle (121) fastened to the bore surface (122) is fixed to the housing (110). The flap (121) has an axial hole in which the member (120) can slide during operation of the closing and damping mechanism. The inner surface (122) of the bore within the housing provides first (123) and second (124) chambers in which hydraulic fluid is provided. The baffle (121) contains a one-way valve (200), similar to the one-way valve described with reference to Figures 1-6.

The closing function is provided by a spring (140) which surrounds the axial rod (120) and is retained at the end remote from the hinge by a screw cap (141), screw (142) and sealing ring (143). When the hinge is moved to the open position, the end of the spring away from the cap pushes against the flap (121).

During the opening of the hinge, the shuttle, including the axial rod (120), proximal end (144) and linkage (145), together with the cover assembly (141, 142, 143), will move out of the housing (110) towards the fixed plate (111). Figures 30 to 34 show the successive stages of opening. In Figure 32, the hinge is open 90° and the spring (140) is compressed between the end cap (141) and the flap (121). When the door is released, spring (140) extension will urge the door to the closed position shown in FIG.

The damping function of the valve shown in Figures 27-36 is similar to that described with reference to the previous figures.

Passage (125) communicates with the second chamber (124) through adjustable valve (126) to passage (127). A passage (127) communicates with the first chamber (123) to provide controlled variable damping due to the restriction of the adjustable valve (126). Valve (126) is also in communication with the first chamber (123) via a second adjustable valve (128) and passage (129). The outlet (130) of the channel (127) and the outlet (131) of the channel (129) are located at different axial positions within the housing (110). The shuttle body (118) has an end portion (132) which is sealed by one or more sealing rings (133) to prevent oil from escaping from the chamber. When the hinge is in the closed position, the baffle (121) closes the openings (130, 131) preventing oil from flowing through the channels (127, 129).

The end portion (132) is arranged such that as the hinge opens from the position shown in FIG. 30, through the positions shown in FIGS. 30, 31 and 32 until the position shown in FIG. Axial movement of plate (121), where openings (130) and (131) will open, allows oil to flow and pass through passage (125), valve (126) and passage (127), and through passage (125), Valve (128) and passage (129).

In Figure 32, the hinge is shown opened to 90 degrees. In this position, the shuttle body (118) is pulled outwardly from the housing (110), so that both openings (130, 131) will open. During closure, as shown in Figure 31, the velocity of oil through passages (127, 129) to passage (125) is at a maximum. When the hinge reaches a 25 degree angle as shown in Figure 30, the channel (129) closes, restricting oil flow and increasing the amount of damping. When both channels (127, 129) are closed, the greatest amount of damping is achieved as the hinge approaches zero degrees as shown in Figure 29 .

In Figure 29, maximum damping is achieved as the hinge approaches the closed position. In Figure 30, a lesser degree of damping is achieved, while in Figure 31 a lesser degree is achieved in the fully open position. As the hinge rotates from the open position to the closed position, the damping force provided by the hinge increases. Therefore, slamming of the door is avoided.

In the fully closed position shown in Figure 30, the spring (140) is fully extended and the axial rod (120) of the shuttle is fully received in the tubular bore of the housing (110). The respective outlets (130, 131) from the channels (127, 129) are closed by the inner surface of the baffle (121). Oil is prevented from passing through and through the valves (126, 128). As the hinge opens, oil can flow from the second chamber (124) to the first chamber (123) through the check valve (200) until the fully open position shown in FIG. 33 is reached. As the hinge closes under the action of spring (140) or manual pressure, the one-way valve (200) closes. Oil is forced into the openings (130, 131), along passages (127, 129) and through adjustable valves (126, 128), respectively, and then back through the Axially extending passage (125) and outlet (146).

As the hinge reaches the 90° position shown in Figure 32, the oil will continue to flow.

When the hinge reaches the 30° position shown in Figure 31, by setting the valves (126) and (128), the flow of oil and thus the degree of damping will be controlled, the surface of the annular channel of the baffle (121) This exit (130) would be blocked. The flow of this oil will be restricted so that oil can only pass through passage (129) and outlet (132). In this position, the degree of damping is controlled by valve (128). As the hinge reaches the fully closed position shown in Figure 30, both outlets (130, 131) close within the annular aperture of the flapper (121), providing maximum damping and preventing the hinged door from slamming shut.

Adjusting the valves (126, 128) controls the maximum flow of oil as the hinge closes, providing an upper limit to the speed at which the hinged door can close, either under the action of the spring (140) or by applying manual pressure .

The various closing stages of the hinge are shown in FIG. 34 .

Figures 35 and 36 show the shuttle in more detail.

Figures 37-40 show another alternative hinge for use in the corner of a door frame. The housing (170) is pivotally connected to the fixture (171). A fixing plate (172) allows the housing to be screwed to the edge of the door. This hinge incorporates a damping arrangement, together with a self-closing spring, with a stop position that stays open.

Figures 38 to 40 show the various stages of opening. In Figure 38 the hinge is closed, in Figure 39 the hinge is partially open, and in Figure 40 the hinge is fully open at 90 degrees.

A spring (174) urges the shuttle (173) inwardly into the housing (170). The spring acts on the fixed baffle (175) and end plate (176) of the shuttle. As the hinge opens, the spring is compressed as shown in FIG. 40 . When released, the spring (174) will urge the shuttle (173) into the housing (170), causing the damping oil to circulate, as described in the previous embodiment, through the channel (177) and through the Adjust valve (178).

The head (179) of the shuttle has a pair of annular sockets (180) arranged to receive the followers (181) of the corresponding protrusions (183). The protrusions are biased from the housing towards the linkage by a spring (182). Section A-A of Figure 40 shows this arrangement.

The hinge of the present invention can use compressed air or other gas as the hydraulic fluid instead of oil or hydraulic fluid. References to fluids or oils in this description shall also be construed accordingly.
