It is preferably composed of POM) or polytetrafluoroethylene (PTFE). Since the second spacer 52 is provided so as to be exposed to the outside, it looks good when it is made of the same material as the first tube 211 and the second tube 221.

Next, taking as an example the opening and closing of the door using the hinge configured as described above, the operation when one of the two objects 11 and 12 is attached so that the other can be opened and closed and The effect will be described.

As shown in FIGS. 1, 7, and 8, one of the two objects 11 and 12 is pressed or pulled with respect to the other, and the included angle between the first wing plate 21 and the second wing plate 22. One of the first wing plate 21 and the second wing plate 22 with respect to the other is changed from the closed state (for example, FIG. 7) where 0 is 0 degree to the open state (for example, FIG. 1) where it is approximately 90 degrees. When rotated, either the first wing plate 21 or the second wing plate 22 rotates and the tubes of the cam units 6 and 7 pass through the first pipe body 211 or the second pipe body 221. The bodies 61 and 71 are interlocked and rotated. Here, since the fitting block 632 of the distal cam member 63 is fitted in the first cutout groove 6112 of the first tubular portion 611 and the second cutout groove 6123 of the second tubular portion 612. For example, when the first wing plate 21 is rotated, the distal cam member 63 and the proximal cam member 64 are rotated in association with the rotation of the tube body 61, and the second wing plate 22 is rotated. Since the second tubular body 221 is rotated together with the base member 41 and the axle 43, the proximity inclined surface 641 of the proximal cam member 64 is abutted against the contact surface 434 of the axle 43. When the proximity inclined surface 641 of the proximal cam member 64 is pushed against the contact surface 434 of the axle 43, the block member 622 of the hydraulic module 62 is pushed by the axle 43, and the projecting column 6213 of the module body 621 is pushed. As a result, the rotational speeds of the first wing plate 21 and the second wing plate 22 can be controlled, and the elastic member 623 is brought into contact with the contact surface 432 of the axle 43 to compress the elastic member 623. , Restoring force / actuating force is accumulated.

Have and. The end 322 of the torque spring 32 is fixed to the axle 42 and positioned.

When the second uneven portion 333 of the adjusting member 33 and the first uneven portion 3111 of the first tube portion 311 are fitted together, a tool (not shown) is placed in the adjustment hole 331 exposed to the outside. By inserting and turning, the torque spring 32 having the end portion 321 fitted in the vertical groove 334 is interlockedly rotated, and a restoring force (acting force) is generated.

There are a plurality of ring members 34, and the first pipe portion 311 and the second pipe portion 312 surround the ends 321 and 322 of the torque spring 32 and prevent the adjustment member 33 and the axle 42 from being detached. Between the first pipe portion 311 side and the second pipe portion 312, and the end portion side of the first pipe portion 311 away from the second pipe portion 312, respectively.

The set screw 35 is screwed into the first tube portion 311 of the tube body 31 so as to be inserted into the localization groove 332 of the adjustment member 33 via the first tube portion 311 of the tube body 31. This makes it possible to limit the movement of the adjusting member 33 along the axial direction X.

As shown in FIGS. 9, 10 and 12, the base member 41 has a fixing hole formed in one end face in the axial direction of the base member 41 along the axial direction and having a rectangular cross section with respect to the axial direction. 411, a positioning hole 412 extending in the axial direction of the other end surface of the base member 41 along the axial direction, and having a diameter larger than that of the fixing hole 411 so as to spatially communicate with the fixing hole 411; And a kerf 413 (only one of which is shown in FIG. 9) formed by cutting out from one end face in the axial direction of the peripheral edge portion of the.

In this example, the axle 42 is also called a torsion shaft for mounting and positioning the torque spring 32, and is provided so as to extend along the axial direction via the end coil portion 323 and the middle coil portion 324 of the torque spring 32. The shaft portion 421 is provided so as to be inserted into the fixing hole 411 and the localization hole 412 of the base member 41, and the projecting edge portion 423 protruding in a brim shape perpendicular to the axial direction is formed. The projecting edge portion 423 is cut from its edge so that the cut end 422 corresponds to the cut groove 413 of the base member 41.

One end portion 322 of the torque spring 32 in the cam unit 3 is extended to the cut opening 422 of the axle 42 and inserted into the cut groove 413 of the base member 41 to be connected.

As shown in FIG. 14, the second wing plate 22 may be fitted in the U-shaped recess of the first wing plate 21 and arranged in a single plane. As a result, when the two objects 11 and 12 (see FIG. 1) are connected using the hinge according to this example, a gap between the two objects 11 and 12 is substantially equal to or slightly larger than the thickness of the first wing plate 21. Therefore, the present invention is applicable to door frames with small gaps, hinged doors, etc.

When the two objects 11 and 12 are connected and attached, the first wing plate 21 is moved to abut against the side edge 111 of the object 11 to move the first wing. The plate 21 can be quickly and correctly positioned with respect to the object 11, and by moving the second contact surface 223 of the second wing plate 22 to abut the side edge 121 of the object 12, The wing plate 22 can be quickly and correctly positioned with respect to the object 12. In this way, the objects 11, 12 can be mounted such that they can be quickly and correctly positioned relative to each other and can be pivoted smoothly.

As shown in FIGS. 9, 14, and 15, when one of the first wing plate 21 and the second wing plate 22 is rotated with respect to the other by an external force, each axle 42 corresponds to the other. The cam spring 3 is rotated with respect to the tube body 31 of the cam unit 3, and the torque spring 32 is twisted in one direction. When the torque spring 32 is twisted, the first distance D1 and the second distance D2 are narrowed to generate a restoring actuating force. When the external force disappears, the torque spring 32 is repelled and restored, and one of the first wing plate 21 and the second wing plate 22 is rotated in the opposite direction to the other.

At this time, in the hinge according to the second embodiment, if the first distance D1 is smaller than the second distance D2, even if the entire length of the torque spring 32 remains unchanged, for example, The return torque increased by adjusting the torque spring by one graduation is 15 kg, but the end coil portion 323 of the torque spring 32 in this example has three tightly wound coils with the first distance D1 being substantially zero. Therefore, the torque spring 32 increases the return torque by 15 kg×3 by adjusting one scale. It should be noted that the adjustment for one graduation means moving from any number on the graduations 0 to 7 engraved on the end face of the first pipe portion 311 in FIG. 9 to an adjacent number.

Here, the two torque springs 32 are twisted by an external force, and the two adjacent end coil portions 323 and 323 are abutted against each other (that is, D1=0, D2≠0), and further correspond to the corresponding adjustment member 33. It should be noted that relative rotation with the axle 42 can deform only the middle coil portion 324 (since the end coil portion 323 cannot be further deformed). As a result, even when the middle coil section 324 and the end coil section 323 have the same number of winding coils, when the corresponding adjusting member 33 and the corresponding axle 42 are relatively rotated by an external force by a predetermined angle, Due to the increase in the restoring force accumulated in the torque spring 32, the end coil portions 323 and 323 are abutted against each other, and the triple restoring torque can be obtained by only adjusting one scale.

As an example, when the adjustment member 33 is rotated through the hexagonal adjustment hole 331 and the torque spring 32 is interlocked and rotated by one scale, for example, when the scale 1 and the scale 2 are rotated, the torque spring 32 is rotated. When the return torque of 15 kg×3×2=90 kg is turned to the scales 2 to 3, the torque spring 32 turns the return torque of 15 kg×3×3=135 kg to the scales 3 to 4. By the torque spring 32, a return torque of 15 kg×3×4=180 kg is obtained. As described above, when the hinge according to the second embodiment is used, a heavy door can be opened. For example, when a relatively heavy door of about 300 kg is opened, three hinges can be opened by using the conventionally used hinge. Although it has to be mounted, when the hinge according to the second embodiment is used, only one hinge (180 kg×2=360 kg) needs to be mounted.

In this way, when the door is closed when the external force is released, the tube body 31 of the cam unit 3 and the first wing plate 21 are rotated in opposite directions by the return torque doubled by the torque spring 32. Can be moved. Further, since the first distance D1 in the end coil portion 323 of the torque spring 32 is smaller than the second distance D2 in the middle coil portion 324, the return torque of the torque spring 32 is doubled to restore the force. Actuating force) can be increased.

As described above, when the adjusting member 33 of the cam unit 3 is rotated by using a tool (not shown) and the torque spring 32 is rotated by a predetermined angle via the adjusting member 33, the torque force of the torque spring 32 is increased. Can be increased or decreased, the force to open and close the door can be adjusted and controlled, and it can be performed smoothly even when the door is closed.

It should be noted that the first wing plate 21 is connected to one of the door panel and the door frame, and the second wing plate 22 is connected to the other of the door panel and the door frame.
