Specification

Hinge with damper

Technical field

The present invention relates to a hinge with a damper, for example, which is attached between a case such as a box and a door thereof and can be suitably used for opening and closing the door in a buffered manner. Background art

[0002] Various hinges with a damper used to open and close the door in a buffered manner have been conventionally proposed (see Patent Literatures 1 to 3). The force incorporated in the components (see Patent Documents 1 and 2), the hinge and the damper are completely independent, and the hinge and the damper are separately mounted between the case and the door (See Patent Document 3).

[0003] One example of a hinge with a built-in damper is disclosed in Patent Literature 1, and this hinge is assembled by inserting a damper part with a bilateral force into a pivot portion of two hinge members.

[0004] However, with such a structure, the structure of the hinge is complicated and the assembly is troublesome. In addition, various structures such as a so-called slide hinge connected via two hinge member counter mechanisms are provided. There is a disadvantage that it cannot be applied to the hinge of the form (1).

[0005] Another example of a hinge with a built-in damper is disclosed in Patent Document 2, and this hinge is a piston-type bellows mounted between a free end of a lever pivotally supported by a hinge arm and a hinge arm. With a damper.

[0006] The hinge with a built-in damper having this structure is a biston-type damper provided between the hinge arm and the lever. Therefore, the moving direction of the hinge and the moving direction of the damper are different, so that the damper can move from linear motion. With the dislodged movement, assembling of the hinge is troublesome, and there is a disadvantage that it cannot be applied to various types of hinges.

[0007] As shown in Patent Document 3, if the hinge and the damper are configured completely independently, they must be separately mounted between the case and the door, which requires a great deal of labor for mounting. If the mounting position is wrong, the movement of the hinge and the movement of the damper will interfere and interlock with each other. Therefore, setting the mounting position is troublesome, and the mounting work cannot be performed efficiently.

BEST MODE FOR CARRYING OUT THE INVENTION

[0025] Referring to the drawings, an embodiment of the present invention will be described in detail. Figs. 1 to 7 show a hinge 10 with a damper according to an embodiment of the present invention. The hinge 10 with a damper includes a hinge 20 including first and second hinge members 21 and 22 that are pivotally connected to each other, and a damper that controls the pivotal movement of the first and second hinge members 21 and 22. 30.

As shown in FIGS. 1 to 7, the first hinge member 21 of the hinge 20 includes a pair of mounting flanges 21F which are engaged with the open end surface 12E of the case 12 and fixed by screws (not shown). In the illustrated embodiment, the second hinge member 22 of the hinge 20 has a form of a cup that fits into the recess 14R of the door 14, and is similarly fixed to the back surface 14B of the door with a screw (not shown). It has a mounting flange 22F.

In the illustrated embodiment, a link arm 23 (see FIG. 4), which also has a pair of upper and lower arm partial forces, is disposed between the first and second hinge members 21 and 22 of the hinge 20. One end of the arm 23 is pivoted by a pivot pin 25 between a pair of side arms 24, 24 of the first hinge member 21. The other end of the link arm 23 is pivotally supported by a pivot pin 26 (see FIG. 7) in the recess 22R of the second hinge member 22.

As shown in FIG. 1 to FIG. 3, when the door 14 is closed, the link arm 23 enters the cup-shaped second hinge member 22 so that the first and second hinges 20 move. When the hinge members 21 and 22 are folded so as to be substantially perpendicular to each other, and as shown in FIGS. 4 to 6, when the door 14 is open, the link arm 23 is separated from the cup-shaped second hinge member 22. Then, the first and second hinge members 21 and 22 are unfolded so as to be substantially 180 degrees.

[0029] The damper 30 has a first end having one end pivotally supported by a pivot pin 31 on a pair of side arms 24, 24 of the first hinge member 21, as can be seen in particular from Figs. 4 to 6. An arm 32, a second arm 34 having one end pivotally supported by a pivot pin 33 on a mounting flange 27, 27 of the second hinge member 22, and the other of the first and second arms 32, 34. And damper force generating means 40 provided between the ends. In the illustrated form, one end of the first arm 32 is pivotally supported by the pivot portion of the lower arm portion of the link arm 23 so that the pivot pin 31 also serves as the pivot pin 25 of the lower arm portion. The pivot portion of the first arm 32 and the pivot portion of the link arm 23 may be located at different positions. In FIG. 7, reference numerals 24H and 24'H (24'H are not shown), pin through holes provided in the side arms 24 and 24 'and through which the pivot pin 31 passes, and reference numeral 31W designates a pivot pin 31 is a synthetic resin washer fitted to 31.

[0030] In the illustrated embodiment, the damper force generating means 40 includes a damper body 41 that generates a damper force between a fixed portion 42 and a movable portion 43, which will be described in detail later. One end of the rotating shaft 43S (see FIG. 8), which is a part, slightly protrudes from the fixing portion 42, and the other end of the second arm 34 is connected to the protruding end 43SP of the rotating shaft 43S of the damper body 41 later in detail. The first arm 32 is fixed as described, and the other end of the first arm 32 is fixed integrally to the fixing portion 42 (see FIGS. 2, 5 and 11), and the relative positions of the first and second arms 32 and 34 are adjusted. A proper rotation generates a damper force.

In the illustrated embodiment, the fixed portion 42 of the damper main body 41 has a cylindrical case 42C force as shown in FIG. 8, and the movable portion 43 of the damper main body 41 has a structure as shown in FIGS. 8 and 9. , A rotating shaft 43S rotatably arranged in a cylindrical case 42C that is a fixing portion 42, and the rotating shaft 4S. It consists of a resistance piece 43R fixed to 3S and spread like a blade around a rotation axis 43S, and a viscous fluid (not shown) filled in a cylindrical case 42C. A hook-shaped fixing piece 43RP is provided on one end of the resistor 43R, and the resistor 43R engages the fixing piece 43RP with a notch 43SN of a large diameter portion 43SL provided at one end of the rotation shaft 43S. And have been fixed. As already mentioned, one end 43SP of the rotating shaft 43S protrudes slightly from the corresponding end of the cylindrical case 42C (see FIG. 7).

[0032] In this damper 30, when the movable part 43 tries to rotate relatively to the fixed part 42, the resistor 43R of the movable part 43 receives resistance in the viscous fluid, and this relative rotation is rapidly made. Generates a damper force to brake what happens.

As shown in FIGS. 7 and 10, the second arm 34 is composed of a pair of arm portions 34A, 34A interconnected by a connecting portion 34C. It is attached via a spacer 35 between the arm portions 34A and 34A '. The spacer 35 has a thickness substantially corresponding to the length of the protruding portion of the rotating shaft 43S.

[0034] One arm portion 34A of the second arm 34 has a non-circular fitting hole 34AH that fits into the non-circular outer surface of the protruding end 43SP of the rotating shaft 43S, as shown in Figs. The second arm 34 and the rotating shaft 43S are fixedly connected by the non-circular fitting portion. As described above, it is preferable that the fitting portion be a non-circular fitting hole, because the second arm 34 can rotate together with the rotation shaft 43S without being fixed to the rotation shaft 43S by a screw or the like. The “non-circular” of the non-circular fitting hole 34AH and the non-circular fitting portion is typically a “square”, but if both can rotate together, it is not a “square”. In addition, the term includes an “elliptical shape”, a modified circular shape including a partly circular shape, and other arbitrary shapes.

As shown in FIGS. 7 and 8, the other arm portion 34 A of the second arm 34 has a fixing cap 36 fixed to the fixing portion 42 of the damper main body 41 via a spacer 35 and a speaker. It is disposed so as to be freely rotatable with the sub-35. 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 (see FIG. 7) of the arm portion 34A of the second arm 34. 8 and FIG. 10), two rotation stopper pins 36P that also project the force of the shaft portion 36S, and a through hole 36H that extends through the center of the shaft portion 36S and through which a set screw 37 penetrates. While the cylindrical case 42C has an end corresponding to the arm portion 34A, In addition, a screw cylinder 42CT into which the set screw 37 is screwed has a closed end plate 42CC protruding inward. Therefore, the arm portion 34A of the first arm 34 is rotatably supported by the shaft portion 36S of the fixed cap 36.

[0036] The rotating shaft 43S, which is a movable portion, has a bearing concave portion 43SR in which the screw cylinder 42CT is engaged to rotatably support the rotating shaft 43S on the cylindrical case 42C. The end on the side has a bearing plate 42CB that rotatably supports the opposite end of the rotating shaft 43S. The bearing plate 42CB is arranged around the rotating shaft 43S so as to prevent the viscous fluid inside from leaking. It has a groove 42CG in which an O-ring 38 is housed. Therefore, it is understood that the rotating shaft 43S, which is the movable portion 43 of the damper 30, is rotatably supported by the screw cylinder 42CT of the cylindrical case 42C and the bearing plate 42CB. In order to prevent the arm portion 34A of the second arm 34 from slipping out of the rotation shaft 43S force, as shown in FIGS. 7 and 8, the arm portion 34A engages with the outer surface of the arm portion 34A and protrudes from the rotation shaft 43S. The rod 39R of the fixing cap 39 is press-fitted into the recess at the end of.

[0037] 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, 34A of the second arm 34, and is inserted into the square fitting hole 34AH of the arm portion 34A. The projecting end 43SP of the rotating shaft 43S, which is the movable portion 43 of 41, is fitted, and the fixed cap 39 is attached to the outside of the rotating shaft 43S and the arm portion 43A. Thereafter, the spacer 35 is inserted into a gap formed between the arm part 34A 'on the opposite side and the damper body 41, and the fixing cap 36 is attached from the outside of the arm part 34A. As described above, 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 is provided between the arm portion 34A 'and the damper body 41. The damper main body 41 can be easily attached to the second arm 34 in accordance with the gap of.

In the hinge 10 with a damper of the present invention, as shown in FIGS. 1 to 3 and FIGS. 4 to 6, since the damper 30 is attached to the hinge 20, the first and second hinges of the hinge 20 are provided. The members 21 and 22 can be attached simply by fixing them to the case 12 and the door 14, respectively. When the door 14 is closed, as shown in FIGS. 1 to 3, the link arm 23 enters the cup-shaped portion of the second hinge member 22 so that the first and second hinge members 21 and 22 are substantially at right angles. Fold as Rarely, when the door 14 is opened, as shown in FIGS. 4 to 6, the link arm 23 comes out of the cup-shaped portion of the second hinge member 22 and the first and second hinge members 21 and 22 are almost It unfolds to 180 degrees. On the other hand, the damper 30 having the first and second arms 32 and 34 pivotally supported by the first and second hinge members 21 and 22, respectively, in accordance with the opening / closing operation, provides the first and second arms. Due to the relative rotation of the arms 32 and 34, the viscous fluid resists between the fixed part 42 and the movable part 43, and the opening / closing operation is buffered.

As can be seen from FIGS. 1 to 3 and FIGS. 4 to 6, when the door is closed, the damper 30 is disposed between the right-angled arrangement of the first and second hinge members 21 and 22 inside the case. When the door is in the open state, it is arranged almost in parallel with the first and second hinge members 21 and 22 in the open state. It can be seen that the degree of decrease is small.

[0040] As described above, the damper 30 is attached to the hinge 20 in a completed state, and it can be understood that the assembly of the damper with the hinge is easier than the conventional one built in the hinge member. .

Further, since the damper 30 is attached to the hinge members 21, 22 via the two arms 32, 34, the movement of the hinge members 21, 22 is relative to the two arms 32, 34 of the damper 30. Since the rotation is converted into a proper rotation, and this rotation induces a damping action of the damper body 41, it can be seen that the hinge 23 can be moved smoothly without interfering with the movement of the hinge 20 and the movement of the damper 30.

Further, as described above, the rotation shaft 43S of the damper 30 has a portion slightly protruding from one side of the damper body 41, and the spacer 35 has a length of the protrusion 43SP of the rotation shaft 43S. The damper body 41 including the projecting portion 43SP of the rotating shaft 43S is inserted between the pair of arm portions 34A, 34A of the second arm 34, and then the projecting portion of the rotating shaft 43S is formed. The part 43SP fits into one arm part 34A of the pair of arm parts 34A, 34A ', and the spacer 35 is arranged between the other arm part 34A' and the damper body 41, thereby forming the damper body. The 41 and the first arm 34 can be easily assembled, so that the armed damper 10 can be efficiently assembled.

In the above embodiment, the hinge 20 is linked between the first and second hinge members 21 and 22. Force Having Arm 23 The present invention can be similarly applied to a configuration in which the first and second hinge members 21 and 22 are directly pivotally supported.

[0044] A hinge 10 with a damper according to another embodiment of the present invention is shown in Fig. 13 and subsequent figures, and the same portions are denoted by the same reference numerals.

In this embodiment, the fixed portion 42 of the damper main body 41 has a cylindrical case 42C force, similar to the previous embodiment. The movable portion 43 of the damper main body 41 has a structure similar to that of FIGS. As shown in the figure, a rotating shaft 43S rotatably supported by an inner cylindrical portion 42CI of a cylindrical case 42C, which is a fixing portion 42, a resistor 43R fixedly attached to the rotating shaft 43S, and a cylindrical case. 42C and a viscous fluid 43F (see FIGS. 15 to 18) filled as described later.

In the illustrated embodiment, the inner cylinder 42CI of the cylindrical case 42C is formed integrally with the main body portion 42CB of the cylindrical case via an end wall 42CW, and one end of the rotating shaft 43S is connected to the cylindrical case 42C. The stopper 43W rotatably supported by the concave part 42CR of the inner cylinder part 42CI of the inner cylinder part 42C prevents it from coming off, and a resistor 43R is attached to the other end of the rotary shaft 43. It has a retaining function opposite to the stopper plate 45. As can be seen from FIG. 14, the end of the rotating shaft 43S on the resistor 43R side has a head portion 43SH that engages with the recess 43RR of the resistor 43R, and the opposite end of the rotating shaft 43S is pulled out. The crimping portion 43ST is crimped to abut against the bottom of the recess 43WR of the retaining plate 43W. Therefore, when the second arm 34 rotates with the opening and closing of the door 14, the rotating shaft 43S also rotates together with the resistor 43R while receiving the resistance of the viscous fluid 43F against the fixed part 42, and A damper action is given to the opening and closing, and the details will be described later.

[0047] In this embodiment, the resistor 43R of the damper 30 includes a switching mechanism 44 that switches between a damper stroke portion that imparts a damper action to the opening and closing of the door 14 and a free stroke portion that cancels the damper action. .

As shown in FIG. 14, the switching mechanism 44 includes a middle cylinder part 42CM fixed inside the cylindrical case 42C parallel to the inner cylinder part 42CI and a main body part 42CB of the cylindrical case 42C. And an intermediate annular member 44M rotatably supported by the inner and outer O-rings 42IB and 420B on the main body portion 42CB and the inner cylindrical portion 42CI of the cylindrical case 42C. A pair of keys that are displaced by being engaged with the engagement groove 44ME penetrating in the radial direction of the intermediate annular member 44M and switching the intermediate annular member 44M to either the side between the cylindrical case 42C side and the resistor 43R side. Member 44K is also strong. In FIGS. 13 and 14, reference numeral 42BM denotes a movable 43-side inner cylinder fixedly attached to the intermediate annular member 44M and disposed between the inner cylinder portion 42CI and the intermediate cylinder portion 42CM of the fixed portion 42. Part. The viscous fluid 43F is also filled between the inner cylinder part 42BM and the inner cylinder part 42CI and the middle cylinder part 42CM on both sides thereof.

[0049] As shown in Figs. 15 to 18, the resistor 43R has a pair of engagement pieces 43RP that engage with a pair of arc grooves 44MG provided inside the intermediate annular member 44M. The intermediate annular member 44M has a pair of engagement pieces 44MP that engage with a pair of arc grooves 42CG formed on the inner surface of the cylindrical case 42C. The engagement pieces 43RP and 44MP and the arc grooves 44MG and 42CG are respectively formed by the resistor 42R and the intermediate annular member 44M or the intermediate annular member 44M and the cylindrical shape depending on the relative rotation direction of the fixed portion 42 and the movable portion 43. The case 42C is allowed to rotate relatively within a predetermined angle range.

[0050] Further, the pair of key members 44K is formed of a cylindrical body having an outer diameter slightly larger than the thickness of the intermediate annular member 44M (see FIG. 15), and these key members 44K are formed of the resistor 43R. The pair of arcuate cam concave surfaces 43RC provided on the outer surface and the V of the pair of arcuate cam concave surfaces 42CC provided on the inner surface of the cylindrical case 42C are slightly shifted in the circumferential direction from the cam concave surface 43RC. It is set to enter! When the key member 44K enters the arcuate cam concave surface 43RC of the resistor 43R of the movable portion 43 (see FIGS. 15 and 16), the intermediate annular member 44M is connected to the resistor 43R, and the key member 44K is fixed to the fixed portion 42. The intermediate annular member 44M is connected to the cylindrical case 42C of the fixing portion 42 when the intermediate annular member 44M enters the arcuate cam concave surface 42CC of the cylindrical case 42C.

[0051] The viscous fluid 43F of the damper 30 is filled between the cylindrical case 42C of the fixed part 42 and the intermediate annular member 44M of the switching mechanism 44 (see Figs. 15 to 18). When the relative movement in the circumferential direction occurs between the upper arm 42C and the intermediate annular member 44M, the viscous fluid 43F receives the resistance to act as a damper, but between the first and second arms 21 and 22. Despite the relative rotational movement, the relative movement between the cylindrical case 42C and the intermediate annular member 44M No damper action will occur unless there is movement!

[0052] The hinge 10 with a damper according to this embodiment is assembled as follows. That is, an intermediate annular member 44M having a middle cylindrical portion 42CM, an annular backup member 42BM, and a key member 44K, which is a component of the switching mechanism 44, is inserted into the cylindrical case 42C of the damper 30. Of the second arm member 34 is inserted between the pair of arm portions 34A, 34A, and then the outer force of the pair of arm portions 34A, 34A, is released. The stopper plate 43W and the resistor 43R are engaged, and finally the rotating shaft 43S is inserted, the head 43SH is engaged with the resistor 43R, and the opposite crimping end is crimped to secure the crimped end. 43ST is formed and assembly is completed.

When the door 14 is closed, the link arm 23 enters the cup-shaped portion of the second hinge member 22 when the door 14 is closed, as shown in FIG. When the hinge members 21 and 22 of the second hinge member 22 and 22 are folded so as to be substantially at right angles, and the door 14 is opened, the link arm 23 comes out of the cup-shaped portion of the second hinge member 22 as shown in FIG. And the second hinge members 21 and 22 are deployed so as to be substantially 180 degrees. These states are the same as the states of FIGS. 1 and 4 of the hinge with damper 10 according to the embodiment of FIGS.

On the other hand, the damper 30 having the first and second arms 32 and 34 pivotally supported by the first and second hinge members 21 and 22 with the opening and closing operation, respectively, The resistance of the viscous fluid 43F between the fixed part 42 and the movable part 43 due to the relative rotation of the arms 32 and 34, and the force to buffer the opening / closing operation This operation changes according to the opening position of the door .

That is, as shown in FIG. 15, when the door is fully closed, the key member 44K of the switching mechanism 44 is engaged with the arcuate cam concave surface 43RC of the antibody 43R. Therefore, when the door is opened, the second hinge member 22 moves obliquely rightward away from the first hinge member 21, so that the second arm 34 of the damper 30 rotates from the state shown in FIG. It rotates counterclockwise about the axis of the shaft 43S to reach the position shown in FIG.

As described above, since the resistor 43R and the intermediate annular member 44A are connected to each other by the key member 44K, the second arm 34R moves from the position in FIG. 15 to the position in FIG. With the rotation of, the resistor 43R and the intermediate annular member 44A rotate counterclockwise along the inner surface of the cylindrical case 42C of the fixed portion 42 while receiving the resistance of the viscous fluid 43F. The key member 44K of the structure 44 is opposed to the arcuate cam concave surface 42CC of the cylindrical case 42C of the fixing portion 42.

[0057] For this reason, the key member 44K that has been engaged with the arcuate cam concave surface 43RC of the resistor 43R until now has an outer cam due to the rising cam surface portion of the arcuate cam concave surface 43RC on the resistor 43R side of the movable part 43. As shown in FIG. 17, the key member 44K enters the arcuate cam concave surface 42CC on the cylindrical case 42C side of the fixing portion 42 as shown in FIG. Therefore, since the resistor 43R is released from the intermediate annular member 44M of the switching mechanism 44, when the first and second arms 21 and 22 rotate relative to each other, the resistor 43R becomes the intermediate annular member of the switching mechanism 44. Move along member 44M. At this time, there is no relative movement between the cylindrical case 42C of the fixed part 42 and the intermediate annular member 44M of the switching mechanism 44, so that the viscous fluid 43F acts as a damper that does not receive resistance. There is no.

This switching state is maintained from the position in FIG. 17 to the position in FIG. 18 (the position corresponding to the fully open position of the door) of the first and second hinge members 21 and 22. It can be opened without.

When the door is fully closed as shown in FIG. 18, when the door is closed, the force is applied to the position shown in FIG. 17 and the position shown in FIG. 16 to become the door fully closed position shown in FIG. 15, for the same reason as described above. The damper function works up to the position of, but the damper function works from the position in FIG. 16 to the fully closed position of the door in FIG. 15 to prevent the door from being closed by shock.

The angle to the half-open position in FIG. 16 in which the door fully closed position force in FIG. 15 also acts on the damper can be set to, for example, 30 °. In this case, when the door starts to open, Although some resistance is received, when the door is closed, the door closes without resistance at first, and the damper works just before the door closes, so that the door can be opened and closed smoothly, which is preferable.

[0061] In the hinge 10 with a damper according to the embodiment shown in Fig. 13 and subsequent figures, similarly to the hinge 10 with the damper according to the embodiment in Figs. 1 to 12, the damper 30 reduces the volume occupied in the case. Since the damper 30 is mounted on the hinge 20 in a completed state, the assembling of the hinged damper becomes easy.

[0062] The same applies to the case where the damper 30 is attached to the hinge members 21 and 22 via the two arms 32 and 34, and the movement of the hinge members 21 and 22 corresponds to the two arms 32 and 32 of the damper 30. The rotation is converted into the relative rotation of 34, and this rotation induces the damping action of the damper body 41, so that the hinge 23 can be smoothly driven without the movement of the hinge 20 and the movement of the damper 30 interfering with each other. I understand.

[0063] Further, the damper 30 inserts a rotating shaft 43S that is a component of the movable part, an intermediate annular member 44M including a key member 44K of the switching mechanism 44, and the like into a cylindrical case 42C that is a fixed part 42, Finally, by inserting the rotating shaft 43S and caulking, the damper 10 with the arm can be assembled efficiently.

[0064] In the above two embodiments, the force in which the hinge 20 has the link arm 23 between the first and second hinge members 21 and 22 is not limited to the first and second hinge members. The present invention can be similarly applied to a configuration in which the members 21 and 22 are directly pivoted.

Industrial applicability

[0065] According to the hinge with a damper of the present invention, the damper is attached to the hinge member in a completed state, and it is easy to assemble a damper with a hinge that is not built in the hinge member. The work of attaching the arm can be performed efficiently, and a hinge with a damper can be provided at a low cost, so that industrial applicability is improved.
