Description

Hinge with Damper}

The present invention relates, for example, to a damper-attached hinge that is fitted between a case, such as a box, and a door thereof, and can be most suitably used to open and close the door bufferly.

Although various damper attachment hinges have been proposed from the prior art (see Patent Literatures 1 to 3), which are used for buffer opening and closing of the door, these damper attachment hinges of the prior art are assembled in the components of the hinge. Or (see Patent Documents 1 and 2), the hinge and the damper are configured completely independently, and the hinge and the damper are separately mounted between the case and the door (see Patent Document 3).

One example of a damper built-in hinge is disclosed in Patent Literature 1, and the hinge is assembled by inserting damper parts from both sides into the shaft supporting portions of the two hinge members.

However, such a structure, the structure of the hinge is complicated and the assembly is complicated, there is a defect that can not be applied to various types of hinges, such as the so-called slide hinge that the two hinge members are connected via a link mechanism.

Another example of a damper built-in hinge is disclosed in Patent Document 2, which has a piston-type bellows damper mounted between the free end of the lever axially supported by the hinge arm and the hinge arm.

Since the damper built-in hinge of this structure is a piston type damper provided between the hinge arm and the lever, the damper has a movement away from the linear movement because the damper movement direction and the damper movement direction are different. There was a drawback that became complicated and was not applicable to various types of hinges.

As shown in Patent Literature 3, when the hinge and the damper are completely independent, they must be separately installed between the case and the door, so that it takes a lot of time to attach and when it is out of the mounting position, Since the dampers interfere with each other and cannot be interlocked with each other, the setting of the mounting position is complicated, and there is a drawback in that the mounting work cannot be efficiently performed.

DETAILED DESCRIPTION OF THE INVENTION An embodiment of the present invention will be described in detail with reference to the drawings. Figs. 1 to 7 show a damper attachment hinge 10 according to one embodiment of the present invention. The damper hinge 10 includes a hinge 20 formed from the first and second hinge members 21 and 22 pivotally connected to each other, and a damper 30 for controlling the pivot movement of the first and second hinge members 21 and 22. .

As shown in Figs. 1 to 7, the first hinge member 21 of the hinge 20 has a pair of mounting flanges 21F which are coupled to the opening end surface 12E of the case 12 and fixed by screws (not shown), and the second hinge 20 In the form of illustration, the hinge member 22 has the form of the cup which fits into the recessed part 14R of the door 14, and similarly it has the mounting flange 22F fixed to the back 14B of the door with the screw which is not shown in figure.

In the form of the figure, the link arm 23 (refer FIG. 4) which consists of a pair of upper and lower arm parts is arrange | positioned between the 1st and 2nd hinge members 21 and 22 of hinge 20, One end of the link arm 23 is axially supported by the pivot pin 25 between the pair of side arms 24 and 24 'of the first hinge member 21, and the other end of the link arm 23 is connected to the second hinge member 22. It is axially supported by pivot pin 26 (see Fig. 7) in recess 22R.

As shown in Figs. 1 to 3, the hinge 20 has the link arm 23 in the cup-shaped second hinge member 22 when the door 14 is closed, so that the first and second hinge members 21 and 22 are substantially perpendicular to each other. 4 to 6, and as shown in Figs. 4 to 6, when the door 14 is open, the link arm 23 emerges from the cup-shaped second hinge member 22, and the first and second hinge members 21 and 22 are almost 180 degrees. To be developed.

The damper 30, in particular, as can be seen from FIGS. 4 to 6, has a first arm 32 having one end axially supported by a pivot pin 31 on a pair of side arms 24, 24 ′ of the first hinge member 21, and a second; A second arm 34 having one end axially supported by the pivot pin 33 on the mounting flanges 27 and 27 'of the hinge member 22 and a damper force generating means 40 provided between the other ends of these first and second arms 32 and 34; Since that time. In the form of illustration, one end of the first arm 32 is axially supported by the pivot portion of the lower arm portion of the link arm 23 and the pivot pin 31 also serves as the pivot pin 25 of the lower arm portion. The position may be different from the pivot portion of the link arm 23. In Fig. 7, reference numerals 24H and 24'H (24'H are not shown) are installed at the side arms 24 and 24 ', and the pin through holes through which the pivot pin 31 penetrates, and the reference numeral 31W are fitted to the pivot pin 31. Paper is a synthetic washer.

The damper force generating means 40 consists of the damper main body 41 which generate | occur | produces a damper force between the fixed part 42 and the movable part 43 which are demonstrated later in the figure, The rotating shaft 43S which is a part of the movable part 43 of this damper main body 41 (FIG. 8) is projected slightly from the fixing portion 42, and the other end of the second arm 34 is fixed to this projecting end 43SP of the rotary shaft 43S of the damper body 41 as described later, and the other end of the first arm 32 The silver is fixed integrally to the fixing portion 42 (see FIGS. 2, 5 and 11), and the damper force is generated by the relative rotation of the first and second arms 32 and 34.

In the form of illustration, the fixing part 42 of the damper main body 41 is comprised from the cylindrical case 42C, as shown in FIG. 8, and the movable part 43 of the damper main body 41 is a cylindrical part of the fixing part 42, as shown in FIG. 8 and FIG. A rotary shaft 43S freely disposed in the case 42C, a resistor 43R fixed to the rotary shaft 43S and extending in a wing shape around the rotary shaft 43S, and a viscous fluid (not shown) filled in the cylindrical case 42C. A hook-shaped fixing piece 43RP is integrally provided at one end of the resistor 43R, and the resistor 43R is fixed by coupling the fixing piece 43RP to the notch 43SN of the large-diameter portion 43SL provided at one end of the rotating shaft 43S. As already explained, one end 43SP of the rotating shaft 43S protrudes slightly from the corresponding end of the cylindrical case 42C (see Fig. 7).

The damper 30 generates a damper force so that when the movable portion 43 is about to rotate relative to the fixed portion 42, the resistor 43R of the movable portion 43 receives resistance in the viscous fluid and brakes the relative rotation.

As shown in Figs. 7 and 10, the second arm 34 is formed from a pair of arm portions 34A and 34'A interconnected at the connecting portion 34C, and the damper body 41 is between the pair of arm portions 34A and 34A '. It is attached to the spacer 35 via the spacer 35. This spacer 35 has a thickness substantially corresponding to the length of the protruding portion of the rotation shaft 43S.

As shown in FIGS. 7 and 10, one arm portion 34A of the second arm 34 has a non-circular fitting hole 34AH that engages with the non-circular outer surface of the protruding end 43SP of the rotary shaft 43S, and the second arm 34 and the rotary shaft 43S. In this case, the non-circular fitting is fixedly connected. Thus, if the engaging portion is a non-circular fitting hole, the second arm 34 is preferable because it can rotate together with the rotating shaft 43S without being fixed to the rotating shaft 43S by a screw or the like. The non-circular fitting hole 34AH and the "non-circular shape" of the non-circular fitting portion are typically "angular", but if both of them can rotate integrally, other than "angle" or "elliptical", Other circular forms including circles, and any other form.

As shown in FIGS. 7 and 8, the other arm portion 34A 'of the second arm 34 is freely rotated between the fixing cap 36 and the spacer 35 fixed to the fixing portion 42 of the damper body 41 via the spacer 35. do. In particular, as shown in Figs. 8 and 12, the fixing cap 36 has a through hole 35H (see Fig. 7) of the spacer 35 and a through hole 34A'H of the arm portion 34A 'of the second arm 34 (Figs. 8 and 10). A shaft portion 36S penetrating through the shaft, two rotary stop pins 36P projecting from the shaft portion 36S, and a through hole 36H extending through the center of the shaft portion 36S and through which the stop screw 37 penetrates. In the end portion corresponding to the portion 34A ', the screw barrel 42CT, to which the stop screw 37 is screwed, has a closing end plate 42CC which protrudes inward. Accordingly, the arm portion 34A 'of the first arm 34 is rotatably supported by the shaft portion 36S of the fixing cap 36.

In addition, the rotary shaft 43S, which is a movable part, has a bearing concave portion 43SR in which the screw cylinder 42CT is coupled to support the rotation shaft 43S to the cylindrical case 42C freely, and the opposite end of the rotary shaft 43S is rotated in the end portion on the opposite side of the cylindrical case 42C. It has a bearing plate 42CB which supports freely, and this bearing plate 42CB has a groove 42CG in which an O-ring 38 surrounding the rotation shaft 43S is housed so as to prevent leakage of the internal viscous fluid. Therefore, it turns out that the rotating shaft 43S which is the movable part 43 of the damper 30 is freely supported with the screw cylinder 42CT of the cylindrical case 42C, the bearing plate 42CB, and rotation. In order to prevent the arm portion 34A of the second arm 34 from escaping from the rotation shaft 43S, as shown in Figs. 7 and 8, it is coupled to the outer surface of the arm portion 34A and fixed to the concave end of the protruding end 43SP of the rotation shaft 43S. The seal 39R of the cap 39 is press-fitted.

The damper 30 is assembled as follows. As shown in Fig. 7, the damper body 41 of the damper 30 is inserted between the pair of arm portions 34A and 34A 'of the second arm 34, and the movable portion 43 of the damper body 41 is inserted into the square fitting hole 34AH of the arm portion 34A. Engage the protruding end 43SP of the rotary shaft 43S, and attach the fixing cap 39 to the outside of the rotary shaft 43S and the arm part 34A. Thereafter, the spacer 35 is inserted into a gap formed between the arm portion 34A 'on the opposite side and the damper main body 41, and the fixing cap 36 is mounted from the outside of the arm portion 34A'. As already explained. Since the spacer 35 has a thickness substantially corresponding to the protruding length of the protruding end 43SP of the rotating shaft 43S, the spacer 35 corresponds to the gap between the arm portion 34A 'and the damper main body 41, and the damper main body 41 is the second arm. Can be easily attached to 34.

In the damper hinge 10 of the present invention, as shown in FIGS. 1 to 3 and 4 to 6, the damper 30 is attached to the hinge 20, so that the first and second hinge members 21 and 22 of the hinge 20 We can attach just to fix to 12 and door 14 respectively. When the door 14 is closed, as shown in Figs. 1 to 3, the link arm 23 enters into the cup-shaped portion of the second hinge member 22, and the first and second hinge members 21 and 22 are folded at almost right angles. When the door 14 is opened, as shown in Figs. The link arm 23 extends from the cup-shaped portion of the second hinge member 22 so that the first and second hinge members 21, 22 are almost 180 degrees. On the other hand, the damper 30 having the first and second arms 32 and 34 axially supported by the first and second hinge members 21 and 22 respectively according to this opening / closing operation is adapted to the relative rotation of the first and second arms 32 and 34. As a result, the viscous fluid is resisted between the fixed part 42 and the movable part 43, and the opening and closing operation is buffered.

As can be seen from FIGS. 1 to 3 and 4 to 6, the damper 30 slightly protrudes to the inside of the case between the right angled arrangements of the first and second hinge members 21 and 22 in the closed state of the door. In addition, in the open state of the door, since the first and second hinge members 21 and 22 are arranged in parallel with each other, the degree of occupancy in the case is reduced.

As described above, the damper 30 is mounted on the hinge 20 in the completed state, and as shown in the related art, the damper 30 is not embedded in the hinge members 21 and 22, and the assembly of the hinged damper becomes easy.

In addition, since the damper 30 is attached to the hinge members 21 and 22 via the two arms 32 and 34, the movement of the hinge members 21 and 22 is converted into the relative rotation of the two arms 32 and 34 of the damper 30. The rotation induces the damping action of the damper main body 41, so that the movement of the hinge 20 and the movement of the damper 30 do not interfere, and the hinge 23 can be smoothly moved.

In addition, as described above, the rotation shaft 43S of the damper 30 has a portion that slightly protrudes from one side of the damper body 41, and the spacer 35 has a thickness almost corresponding to the length of the protruding portion 43SP of the rotation shaft 43S. The damper main body 41 including the portion 43SP is inserted between the pair of arm portions 34A and 34A 'of the second arm 34, and the protruding portion 43SP of the rotating shaft 43S is one arm portion 34A of the pair of arm portions 34A and 34A'. The damper body 41 and the first arm 34 can be easily assembled by arranging the spacer 35 between the other arm portion 34A 'and the damper body 41. I can do it well.

And in the said embodiment, although the hinge 20 has the link arm 23 between the 1st and 2nd hinge members 21 and 22, in this invention, the 1st and 2nd hinge members 21 and 22 are directly axially supported. The same applies to the form.

The damper attachment hinge 10 which concerns on other embodiment of this invention is shown below FIG. 13, The same code | symbol is attached | subjected to the same part.

In this embodiment, the fixing part 42 of the damper main body 41 is made from the cylindrical case 42 like the previous embodiment, but the movable part 43 of the damper main body 41 is a cylindrical part which is the fixing part 42, as shown to FIG. 13 and FIG. From a rotating shaft 43S whose rotation is freely supported by the inner cylinder portion 42CI of the case 42C, a resistor 43R fixedly fixed to the rotating shaft 43S, and a viscous fluid 43F filled in the cylindrical case 42C as described later (see Fig. 15 to 18). It is.

In the form shown, the inner cylinder 42CI of the cylindrical case 42C is integrally formed in the main body part 42CB of the cylindrical case via the end wall 42CW, and one end of the rotating shaft 43S rotates in the recess 42CR of the inner cylinder part 42CI of the cylindrical case 42C. Falling out is prevented by this freely supported fall stop plate 43W, and a resistor 43R is attached to the other end of the rotation shaft 43, and the resistor 43R has a fall stop function as opposed to the fall stop plate 45. As can be seen from Fig. 14, the end of the resistor 43R side of the rotating shaft 43S has a head 43SH that couples to the recess 43RR of the resistor 43R, and the end of the opposite side of the rotary shaft 43S is a recess of the missing stop plate 43W. It consists of a caulking part 43ST which is fastened to contact the bottom of 43WR. Therefore, when the second arm 34 rotates in response to the opening and closing of the door 14, the rotating shaft 43S also rotates while receiving the resistance of the viscous fluid 43F with respect to the fixing part 42 together with the resistor 43R to impart a damper action to the opening and closing of the door 14, Will be explained later.

In this embodiment, the resistor 43R of the damper 30 is provided with the switching mechanism 44 which switches between the damper stroke part which gives a damper action to opening and closing of the door 14, and the pre stroke part which cancels a damper action.

This switching mechanism 44 is as shown in FIG. It is disposed between the cylindrical part 42CM mounted in the cylindrical case 42C in parallel with the inner cylinder part 42CI and the main body part 42CB of the cylindrical case 42C, and the main body part 42CB of the cylindrical case 42C by O-rings 42IB and 42OB. And the intermediate annular member 44M freely supported by the inner cylindrical portion 42CI and the coupling groove 44ME penetrating in the radial direction of the intermediate annular member 44M, and the intermediate annular member 44M to either the cylindrical case 42C side or the resistor 43R side. The switching displacement consists of a pair of key members 44K. 13 and 14, reference numeral 42BM is an inner cylinder portion on the movable part 43 side which is fixedly mounted to the intermediate annular member 44M and is disposed between the inner cylinder portion 42CI of the fixing portion 42 and the intermediate cylinder portion 42CM. The viscous fluid 43F is also filled between the inner cylinder portion 42BM and the inner cylinder portion 42CI and the middle cylinder portion 42CM on both sides thereof.

As shown in Figs. 15 to 18, the resistor 43R has a pair of engaging pieces 43RP coupled to a pair of arc grooves 44MG provided inside the intermediate annular member 44M, and the intermediate annular member 44M is formed on the inner surface of the cylindrical case 42C. It has a pair of coupling pieces 44MP which couple | bond with the formed pair of arc groove 42CG. These coupling pieces 43RP, 44MP and circular groove 44MG, 42CG have a predetermined angle range between the resistor 42R and the intermediate annular member 44M or the intermediate annular member 44M and the cylindrical case 42C by the direction of relative rotation between the fixed part 42 and the movable part 43, respectively. Allow to rotate relative to

Further, the pair of key members 44K is composed of a cylinder having an outer diameter slightly larger than the thickness of the intermediate annular member 44M (see Fig. 15). These key members 44K are a pair of arc-shaped cam recesses provided on the outer surface of the resistor 43R. It is set to enter either one of the pair of arc-shaped cam recesses 42CC provided on the inner surface of the cylindrical case 42C, slightly away from the surface 43RC and the cam recesses 43RC in the circumferential direction. When the key member 44K enters the arc-shaped cam recessed surface 43RC of the resistor 43R of the movable portion 43 (see Figs. 15 and 16), the intermediate annular member 44M is coupled with the resistor 43R, and the key member 44K is a cylindrical case of the fixing portion 42. When entering the 42C arc cam recessed surface 42CC, the intermediate annular member 44M is joined to the cylindrical case 42C of the fixed part 42. As shown in FIG.

The viscous fluid 43F of the damper 30 is filled between the cylindrical case 42C of the fixing part 42 and the intermediate annular member 44M of the switching mechanism 44 (see Fig. 15 to 18). Thus, the cylindrical case 42C and the intermediate annular member 44M If the relative movement in the circumferential direction occurs between, the damper acts under the resistance of the viscous fluid 43F, but even if there is a relative rotational movement between the first and second arms 21 and 22, the cylindrical case 42C and the intermediate annular member 44M and There is no damper action unless there is a relative movement between.

The damper attachment hinge 10 which concerns on this embodiment is assembled as follows. In the cylindrical case 42C on the side and damper 30, the intermediate cylinder 42CM, the annular backup member 42BM, and the intermediate annular member 44M having the key member 44K, which is a component of the switching mechanism 44, are inserted. Is inserted between the pair of arm portions 34A and 34A 'of the second arm member 34, and then the stop plate 43W and the resistor 43R are coupled from the outside of the pair of arm portions 34A and 34A', and the rotary shaft 43S is finally The head 43SH is inserted into the resistor 43R, the end of the opposite caulking side is fastened to form the caulking end 43ST, and the assembly is completed.

The damper hinge 10 according to this embodiment has the door 14 closed, as shown in FIG. When the link arm 23 enters the cup-shaped portion of the second hinge member 22, the first and second hinge members 21 and 22 are folded at almost right angles, and when the door 14 is opened, as shown in Fig. 18, the link arm 23 is Out of the cup-shaped portion of the second hinge member 22, the first and second hinge members 21, 22 are developed such that they are nearly 180 degrees. These states are the same as those of Figs. 1 and 4 of the damper attachment hinge 10 according to the embodiment of Figs.

On the other hand, the damper 30 having the first and second arms 32 and 34 axially supported by the first and second hinge members 21 and 22 in accordance with the opening and closing operation, respectively, is adapted to the relative rotation of the first and second arms 32 and 34. As a result of the resistance of the viscous fluid 43F between the fixed portion 42 and the movable portion 43, the opening and closing operation is buffered, but this operation varies depending on the opening position of the door.

That is, as shown in Fig. 15, in the fully closed state of the door, the key member 44K of the switching mechanism 44 is coupled to the arc-shaped cam recessed surface 43RC of the resistor 43R. Therefore, when the door is opened from this state, since the second hinge member 22 moves away from the first hinge member 21 in the inclined right direction, the second arm 34 of the damper 30 is centered on the axis of the rotary shaft 43S from the state of FIG. 15. It rotates counterclockwise and becomes the position of FIG.

As described above, the resistor 43R and the intermediate annular member 44A are coupled by the key member 44K, and when moving from the position of FIG. 15 to the position of FIG. The annular member 44A rotates counterclockwise along the inner surface of the cylindrical case 42C of the fixing part 42 while being subjected to the resistance of the viscous fluid 43F. The key member 44K of the switching mechanism 44 is the arc-shaped cam of the cylindrical case 42C of the fixing part 42. It faces the concave surface 42CC.

For this reason, the key member 44K, which has been coupled to the arc-shaped cam recessed surface 43RC of the resistor 43R, is pushed outward by the rising cam face portion of the arc-shaped cam recessed surface 43RC on the resistor 43R side of the movable part 43, and thus the arc-shaped cam recessed surface. Freed from 43RC, as shown in FIG. 17, the key member 44K enters the arc-shaped cam recessed surface 42CC on the cylindrical case 42C side of the fixing portion 42. As shown in FIG. Accordingly, the resistor 43R is released from the intermediate annular member 44M of the switching mechanism 44. When there is a relative rotation of the first and second arms 21 and 22, the resistor 43R moves along the intermediate annular member 44M of the switching mechanism 44. At this time, since there is no relative movement between the cylindrical case 42C of the fixing part 42 and the intermediate annular member 44M of the switching mechanism 44, the viscous fluid 43F does not receive a resistance and does not act as a damper.

This switching state is maintained until the first and second hinge members 21 and 22 reach the position of FIG. 18 from the position of FIG. 17 (the position corresponding to the fully open position of the door), so that the door can be opened without resistance.

When the door is closed from the door opening position in Fig. 18, the door is closed in Fig. 15 through the position in Fig. 17 and the position in Fig. 16, but for the same reason as described above, the damper acts from the position in Fig. 18 to the position in Fig. 17. However, the damper acts from the position of Fig. 16 to the door closing position of Fig. 15 to prevent the door from being shockedly closed.

The angle from the fully closed position of the door of FIG. 15 to the half-opened position of FIG. 16, which is acting as a damper, can be set, for example, to 30 °. In this way, there is a slight resistance when starting to open the door. When the door is closed, the door is initially closed without resistance, and the damper acts immediately before the door is closed, so that the door can be opened and closed smoothly.

Similar to the damper-attached hinge 10 of the embodiment of FIG. 13 or less, and the damper-attached hinge 10 of the embodiment of FIGS. 1 to 12, the damper 30 has a small degree of decreasing the occupancy volume in the case. Since the damper 30 is mounted on the hinge 20 in a completed state, the assembly of the hinged damper is facilitated.

The same applies to the case where the damper 30 is mounted to the hinge members 21 and 22 via the two arms 32 and 34, and the movement of the hinge members 21 and 22 is converted to the relative rotation of the two arms 32 and 34 of the damper 30. As the rotation induces the damping action of the damper main body 41, it can be seen that the hinge 23 can be smoothly moved without interfering with the movement of the hinge 20 and the movement of the damper 30.

In addition, the damper 30 inserts the rotary shaft 43S, which is a component of the movable part, the intermediate annular member 44M including the key member 44K of the switching mechanism 44, and the like, and finally the rotary shaft 43S is inserted into the cylindrical case 42C that is the fixing part 42. By processing, the assembling of the armed damper 10 can be performed efficiently.

In the above two embodiments, the hinge 20 has a link arm 23 between the first and second hinge members 21 and 22, but in the present invention, the first and second hinge members 21 and 22 are directly supported by the shaft. The same applies to the form in which it is made.

According to the damper attachment hinge of the present invention, the damper is attached to the hinge member in a completed state, and is not embedded in the hinge member, and the assembly of the hinge attachment damper is facilitated, and in particular, the operation of attaching the arm to the damper is more efficient. This can be done well, and since the damper hinge can be provided at a low price, industrial usability is improved.
