Description

Rotating damper, slide hinge with rotating damper and its manufacturing method

The present invention relates to a rotary damper attached to a slide hinge.

The slide hinge includes a cup fixed to a door of furniture or the like, a body fixed to a housing of furniture or the like, and at least two arms rotatably connected to the cup and the body. The cup, body, and at least two arms constitute, for example, a four-bar linkage. The trajectory when the door opens and closes is determined by, for example, the slide hinge of the 4-section link mechanism. The slide hinge is a hinge in which the instantaneous center of the door changes as the door rotates. In contrast, a uniaxial hinge is a hinge in which the instantaneous center of the door does not change as the door rotates.

A rotary damper may be attached to the slide hinge to reduce the impact when the door is closed (see Patent Document 1). The rotary damper of Patent Document 1 includes a shaft body and a rotor (rotary damper component) into which the shaft body is inserted. The rotor rotates relative to the shaft body to generate a damper force. A flange portion is provided at one end of the shaft body in the axial direction. When attaching the rotary damper to the slide hinge, insert the end opposite to the flange portion of the shaft body into the mounting hole on the side wall of the slide hinge, crimp the end portion of the shaft body, and attach the shaft body to the slide hinge.

The configuration of the rotary damper 3 is as follows. The rotary damper 3 includes a shaft body 11 and a rotary damper component 12 assembled to the shaft body 11. The rotary damper component 12 of the present embodiment includes a case 13, a rotor 14, and a damper force adjusting mechanism 15.

FIG. 4A shows a perspective view of the rotary damper 3 in an assembled state, and FIG. 4B shows an exploded perspective view of the rotary damper 3.

The shaft body 11 has a first shaft portion 11a, a second shaft portion 11b, and a flange portion 11c. The flange portion 11c is provided between the first shaft portion 11a and the second shaft portion 11b. The flange portion 11c has a larger outer diameter than the first shaft portion 11a and the second shaft portion 11b. The first shaft portion 11a is longer than the second shaft portion 11b. The first shaft portion 11a, the second shaft portion 11b, and the flange portion 11c are integrated. The first shaft portion 11a is inserted into the rotary damper component 12. After insertion, the end of the first shaft portion 11a is crimped. By crimping the end of the first shaft portion 11a, a collar-shaped retaining 11a1 (see FIG. 8) is formed at the end of the first shaft portion 11a. The rotary damper component 12 is arranged between the flange portion 11c of the shaft body 11 and the retaining portion 11a1 of the end portion of the first shaft portion 11a of the shaft body 11.

As shown in FIG. 4B, a detent portion 11a2 having a quadrangular cross section for detenting the movable cam 43, which will be described later, is provided at the tip portion of the first shaft portion 11a. An annular step portion 11a3 and a small diameter portion 11a4 are provided at the tip of the detent portion 11a2. The small diameter portion 11a4 is inserted into the retaining ring 44 of the rotary damper component 12. The retaining ring 44 is sandwiched between the annular step portion 11a3 and the retaining ring 11a1 (see FIG. 8).

As shown in FIG. 3, the case 13 has a cylindrical shape. The case 13 houses at least a part of the rotor 14. A protrusion 13a is formed on the outer surface of the case 13. A pair of

partition walls

13b and 13c are formed on the inner surface of the case 13 so as to project inward (see FIG. 5D). The pair of

partition walls

13b and 13c are arranged at positions separated by 180 ° in the circumferential direction of the case 13.

As shown in FIG. 3, the rotor 14 includes a rotor main body 16 and a gear 17. The gear 17 is fixed to the rotor body 16 so as not to rotate. Through holes through which the shaft body 11 penetrates are formed in the rotor body 16 and the gear 17. The rotor 14 is rotatably supported by the shaft body 11. The gear 17 is abutted against the flange portion 11c of the shaft body 11. The rotor 14 is axially positioned by the flange portion 11c.

FIG. 5 shows a detailed view of the rotary damper 3. 5 (a) is a front view, FIG. 5 (b) is a side view, FIG. 5 (c) is a sectional view taken along line AA, and FIG. 5 (d) is a sectional view taken along line BB. As shown in FIG. 5 (c), the rotor main body 16 has a large diameter portion 16a and a small diameter portion 16b (see also FIG. 3). The large diameter portion 16a is fitted to the end portion of the case 13. As shown in FIG. 5D, the small diameter portion 16b is arranged between the pair of

partition walls

13b and 13c of the case 13. An annular space S1 to S4 is formed between the case 13 and the small diameter portion 16b of the rotor main body 16. The spaces S1 to S4 are sealed by O-

rings

35 and 36. The spaces S1 to S4 are filled with hydraulic oil.

A pair of ridges 16b1 and 16b2 are formed on the small diameter portion 16b of the rotor body 16. The pair of ridges 16b1 and 16b2 are arranged at positions separated by 180 ° in the circumferential direction of the rotor main body 16. Recesses 37, 37 (see FIG. 3) are formed in the ridges 16b1 and 16b2. The

recesses

37, 37 are opened and closed by the

valve bodies

38, 38 that engage the ridges 16b1, 16b2.

As shown in FIG. 5D, the annular space is divided into four spaces S1 to S4 in the circumferential direction by the pair of

partition walls

13b and 13c and the pair of ridges 16b1 and 16b2.

When the rotor 14 rotates in the closing direction (arrow A direction), the

recesses

37 and 37 are closed by the

valve bodies

38 and 38. Therefore, the space S2 and the space S4 become a high pressure chamber, the space S1 and the space S3 become a low pressure chamber, and a damper force that resists the rotation of the rotor 14 is generated. On the other hand, when the rotor 14 rotates in the opening direction (direction of arrow B), the

valve bodies

38 and 38 release the

recesses

37 and 37. Therefore, the hydraulic oil in the low pressure chambers S1 and S3 flows into the high pressure chambers S2 and S4 through the

recesses

37 and 37, and almost no damper force is generated.

As shown in FIG. 4, the damper force adjusting mechanism 15 includes an operating lever 41, a rotating cam 42, a movable cam 43, and a retaining ring 44. The damper force adjusting mechanism 15 adjusts the axially relative position of the case 13 with respect to the rotor 14 to adjust the damper force of the rotary damper 3.

The operating lever 41 has a bottomed cylindrical shape. A rotary cam 42 is non-rotatably fitted to the actuating lever 41. A click pin 41a is integrally formed on the overhanging portion of the operating lever 41. The click pin 41a engages with the jagged portion 43a of the fan-shaped overhang portion of the movable cam 43 so that the rotation position of the rotary cam 42 can be held in several stages.

The rotary cam 42 has a substantially disk shape. A pair of arcuate inclined surfaces 42a are formed on the rotary cam 42. The inclined surface 42a abuts on the protrusion 43d (see FIG. 5C) of the movable cam 43.

As shown in FIG. 4, the case 13 is non-rotatably fixed to the movable cam 43. The movable cam 43 is formed with a hole 43c having a quadrangular cross section into which the detent portion 11a2 of the shaft body 11 is inserted. The movable cam 43 cannot rotate with respect to the shaft body 11 and can move in the axial direction.

When the operating lever 41 is rotated, the rotating cam 42 rotates together with the operating lever 41, and the movable cam 43 that abuts on the inclined surface 42a of the rotating cam 42 moves in the axial direction. Therefore, the case 13 moves in the axial direction with respect to the rotor 14. When the case 13 moves in the axial direction with respect to the rotor 14, as shown in FIG. 5C, the axial gap g1 between the large diameter portion 16a of the rotor body 16 and the

partition walls

13b and 13c of the case 13 becomes narrow. Or, as shown in FIG. 6C, the axial gap g1 becomes wider. If the axial gap g1 is narrowed, the damper force is large, and if the axial gap g1 is widened, the damper force is small. Therefore, the damper force can be adjusted.

As shown in FIG. 4, when assembling the rotary damper 3, the first shaft portion 11a of the shaft body 11 is inserted into the rotary damper component 12 (case 13, rotor 14, damper force adjusting mechanism 15). After that, as shown in FIG. 5C, the first shaft portion 11a of the shaft body 11 is crimped to form the retaining 11a1. The rotary damper component 12 is sandwiched between the flange portion 11c and the retaining portion 11a1 and is positioned in the axial direction. With the above, the rotary damper 3 is completed. When the rotary damper 3 is completed, the rotary damper 3 is tested as needed.

After the rotary damper 3 is completed, the rotary damper 3 is attached to the side wall 5a of the slide hinge 2 as shown in FIGS. 1 (a) and 1 (b). As shown in FIG. 1B, when the rotary damper 3 is attached to the slide hinge 2, the fan-shaped overhanging portion 43b (see FIG. 4A) of the movable cam 43 of the rotary damper 3 is a through hole of the side wall 5b. It fits into the fan-shaped large-diameter hole 9a of 9. As a result, the rotary damper 3 is stopped from rotating.

The rotary damper component 12 is not limited to the above embodiment. For example, the damper force adjusting mechanism may be omitted. Further, the case may be omitted, an annular space may be formed between the rotor and the shaft body, and the annular space between the rotor and the shaft body may be filled with hydraulic oil. Further, instead of the viscous resistance of the hydraulic oil, a damper force may be generated by utilizing the frictional resistance when the rotor rotates relative to the shaft or the case.

FIG. 7 shows a slide hinge 1 with a rotating damper attached to furniture or the like. 7 (a) is a front view, and FIG. 7 (b) is a side view (horizontal cross-sectional view of furniture and the like). d is a door of furniture or the like, and h is a side plate of a housing of furniture or the like. The cup 4 is attached to the door d. The body 5 is attached to the side plate h via the mounting plate 29. The trajectory when the door d opens and closes is determined by the slide hinge 1 with a rotary damper.

FIG. 9 shows an operation diagram of the slide hinge 1 with a rotary damper. 9 (a) shows the opening position of the cup 4, FIG. 9 (b) shows the intermediate position of the cup 4, and FIG. 9 (c) shows the closing position of the cup 4. When the cup 4 rotates from the open position to a predetermined angle in the closing direction, the gear 6a2 of the inner arm 6 and the gear 17 of the rotary damper 3 mesh with each other, and the rotor 14 of the rotary damper 3 rotates in the closing direction. When the rotor 14 rotates in the closing direction, a damper force is generated as described above, and the cup 4 slowly closes.

In the above embodiment, the rotary damper 3 is attached to the body 5, but the rotary damper 3 may be attached to the inner arm 6, the outer arm 7, or the cup 4.

The configuration of the rotary damper 3 of this embodiment has been described above. According to the rotary damper 3 of the present embodiment, the following effects are obtained.

The first shaft portion 11a of the shaft body 11 is inserted into the rotary damper component 12, and a rotary damper configuration is formed between the flange portion 11c of the shaft body 11 and the retaining portion 11a1 of the end portion of the first shaft portion 11a of the shaft body 11. Since the element 12 is arranged, the rotary damper 3 can be attached to the slide hinge 2 after the rotary damper 3 is completed.

Since the retaining 11a1 is formed by crimping the end of the first shaft portion 11a of the shaft body 11, the strength of the retaining 11a1 can be ensured.

The crimped portion 11b1 is formed by crimping the end portion of the second shaft portion 11b of the shaft body 11, and the side wall 5a of the slide hinge 2 is arranged between the crimped portion 11b1 and the flange portion 11c. 11b can be firmly fixed to the side wall 5a.

The rotary damper component 12 is not particularly limited, but it is desirable to include a case 13 and a rotor 14. Further, it is desirable that the rotary damper component 12 includes a damper force adjusting mechanism 15. Since the distance from the flange portion 11c of the shaft body 11 to the retaining 11a1 can be managed with high accuracy, the relative position of the case 13 with respect to the rotor 14 in the axial direction can also be managed with high accuracy.
(Second Embodiment)

In the second embodiment, a U-shaped elastically deformable hook 52 is fixed to the second shaft portion 11b side of the flange portion 11c of the shaft body 11 of the rotary damper 3, and the hook 52 is used to fix the second shaft body 11. The biaxial portion 11b is attached to the side wall 5a of the slide hinge 2. A mounting hole 8 into which the second shaft portion 11b of the shaft body 11 is inserted is formed in the side wall 5a. Further, on the side wall 5a, a pair of

fitting holes

53a and 53b are formed in which the

claw portions

52a and 52b at the tip of the U-shaped hook 52 snap-fit. By inserting the second shaft portion 11b of the shaft body 11 into the mounting hole 8 and snap-fitting the

claw portions

52a and 52b of the hook 52 to the

fitting holes

53a and 53b, the second shaft portion 11b of the shaft body 11 is slid. It is attached to the side wall 5a of the hinge 2. Since the other configurations are the same as those in the first embodiment, the same reference numerals are given and the description thereof will be omitted.
