[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2004-000518 Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, some hinge devices are equipped with a so-called closer mechanism that automatically closes when a certain position is exceeded during the closing operation, and some are equipped with a damper mechanism that absorbs the impact of closing. When attempting to attach such a hinge device equipped with a closer mechanism or a damper mechanism to the rotating portion of the sleeve mirror in the above-mentioned makeup mirror unit, the dimension in the plate thickness direction is limited, so further improvements have been required to make the hinge device equipped with a closer function or a damper function more compact. In addition, when attaching the hinge device to the sleeve mirror side, it is undesirable for the hinge device to be exposed, so in this respect as well, further improvements have been required to make the hinge device equipped with a closer function or a damper function more compact.

[0008] In the present invention, it is preferable that the slider be capable of coming into contact with the outer periphery of the rotating part.

[0009] In the present invention, it is preferable that the motion transmission portion protrudes toward the first hinge portion, and the rotating portion has a first contact portion provided on the outer periphery and capable of contacting the motion transmission portion, and a second contact portion provided at a position different from the first contact portion in the circumferential direction of the outer periphery and capable of contacting the slider.

[0010] In the present invention, it is preferable that the valve includes a gear portion that is rotatable together with the rotating portion about the rotation axis, and the damper damps the closing operation via the gear portion and the rotating portion.

[0016] 1. Overview of the embodiment First, a typical embodiment of the invention disclosed in this application will be outlined. In the following description, as an example, reference numerals in the drawings corresponding to the components of the invention will be written in parentheses.

[0017] [1] In a typical embodiment of the present invention, a hinge device (1) comprises a first hinge portion (10) attached to a first member, and a second hinge portion (20) attached to a second member and pivotally supported on the first hinge portion so as to be capable of opening and closing. The second hinge portion has an operation transmission portion (22) that transmits a closing operation to the first hinge portion. The first hinge portion has a rotating portion (11) that rotates around a rotation axis (111) in response to the closing operation transmitted from the operation transmission portion, an elastic member (12) that applies a biasing force to the operation transmission portion, a slider (13) that is interposed between the operation transmission portion and the elastic member, and a damper (14) that damps the closing operation via the operation transmission portion.

[0018] [2] In the present invention, the slider is capable of contacting the outer periphery (112) of the rotating part.

[0019] [3] In the present invention, the motion transmission portion protrudes toward the first hinge portion, and the rotating portion has a first contact portion (113) provided on the outer periphery and capable of contacting the motion transmission portion, and a second contact portion (114) provided at a position different from the first contact portion in the circumferential direction of the outer periphery and capable of contacting the slider, in the hinge device described in [2].

[0020] [4] In the present invention, the rotating part is provided with a gear part (15) that can rotate around the rotation axis, and the damper damps the closing operation via the gear part, in the hinge device described in [1] to [3].

[0021] [5] In the present invention, the hinge device according to [1] and [2], wherein the motion transmission part is a link mechanism connected to the rotating part.

[0022] [6] In the present invention, the slider is capable of contacting the motion transmission part, in the hinge device according to [1].

[0023] [7] In the present invention, the first member is a panel (530R), and the second member is a mirror (540R).

[0024] 2. Specific examples of embodiments [First embodiment] Hereinafter, the configuration of a hinge device according to a first embodiment of the present invention will be described in detail with reference to the drawings.

[0025] 1 refers to the left side (arrow -x direction) of the hinge device 1, which is the hanging point side of the second hinge section 20 when the hinge device 1 is viewed from the front, and the right side refers to the right side (arrow +x direction) of the hinge device 1, which is the door edge side of the second hinge section 20 when the hinge device 1 is viewed from the front. Therefore, the left-right direction or horizontal direction is referred to as the arrow x direction.

[0026] Additionally, the upper side refers to the upward direction (arrow +z direction) when viewed from the front of the hinge device 1, and the lower side refers to the downward direction (arrow -z direction) when viewed from the front of the hinge device 1. Therefore, the vertical direction or the direction of gravity is the arrow z direction.

[0027] Furthermore, the depth direction or front-to-back direction, which is perpendicular to the x and z directions, is designated as the arrow y direction, and the back side of the hinge device 1 on the paper is designated as the arrow +y direction, and the front side is designated as the arrow y direction. Additionally, the closed side, where the second hinge unit 20 closes toward the first hinge unit 10, is the rotation direction in which the second hinge unit 20 closes toward the back side (arrow a direction) on the paper, and the open side, where the second hinge unit 20 opens toward the first hinge unit 10, is the rotation direction in which the second hinge unit 20 opens toward the front side (arrow b direction) on the paper. Therefore, the opening / closing direction is designated as the direction of the arrow ab in which the second hinge unit 20 describes an arc. However, the opening / closing direction, up-down direction, and left-right direction described above are used for convenience of explanation and may be defined as different directions depending on the usage situation in which the hinge device 1 is placed.

[0028] Fig. 1 is a perspective view of a hinge device 1 according to a first embodiment of the present invention. Fig. 2 is an exploded perspective view of the hinge device 1 according to the first embodiment. Fig. 3 is a perspective view of a makeup mirror unit 500 equipped with a three-way mirror to which the hinge device 1 according to the first embodiment is attached. Fig. 4 is a perspective view showing a state in which panels 530R, 530L of the makeup mirror unit 500 equipped with a three-way mirror to which the hinge device 1 according to the first embodiment is attached are opened.

[0029] The hinge device 1 is used in a makeup mirror unit 500 that includes, for example, a cabinet 510, a primary mirror 520 as a three-way mirror, and side mirrors 540R and 540L, and has a storage section provided at the rear of the side mirrors 540R and 540L, as shown in Figures 3 and 4.

[0030] In the makeup mirror unit 500, the side mirrors 540R, 540L are attached to the cabinet 510 via panels 530R, 530L. The panels 530R, 530L are attached to the left and right sides of the main mirror 520 on the front side by panel hinge devices 550 so as to be rotatable horizontally.

[0031] The hinge device 1 is used to rotatably mount side mirrors 540R, 540L to panels 530R, 530L in the makeup mirror unit 500. Specifically, the hinge device 1 shown in FIGS. 1 and 2 rotatably mounts the upper side of the side mirror 540R on the right side as viewed from the primary mirror 520 to the panel 530R. In the makeup mirror unit 500, the lower side of the side mirror 540R is rotatably mounted to the panel 530R by a hinge device 1RL. The upper side of the side mirror 540L is rotatably mounted to the panel 530L by a hinge device 1LU, and the lower side is rotatably mounted to the panel 530L by a hinge device 1LL. In other words, the side mirrors 540R, 540L are rotatably mounted to the left and right sides of the primary mirror 520 by the hinge devices 1, 1RL, 1LU, and 1LL in the horizontal direction. In the following explanation, the hinge device 1 will be mainly described.

[0032] As shown in FIGS. 1 and 2, the hinge device 1 includes a first hinge portion 10 and a second hinge portion 20.

[0033] The second hinge portion 20 is attached to a second member, for example, the sleeve mirror 540R of the makeup mirror unit 500, and is pivotally supported so as to be openable and closable relative to the first hinge portion 10. The second hinge portion 20 has a second hinge body 21 and an operation transmission portion 22.

[0034] The second hinge body 21 is a member that serves as a base for attaching the second hinge part 20 to the sleeve mirror 540R and for attaching the motion transmission part 22. The second hinge body 21 has a shaft hole 212 and screw holes 213 and 214.

[0035] The shaft hole 212 is a hole for inserting a shaft pin 164 and a shaft bush 165 to pivotally support the second hinge section 20 relative to the first hinge section 10 so that the second hinge section 20 can be opened and closed. The second hinge section 20 is pivotally supported in the hinge shaft hole 163 of the base section 16 of the first hinge section 10 by the shaft pin 164 and the shaft bush 165, and is thereby attached to the first hinge section 10 so as to be rotatable about the axis A1. The screw hole 213 is a hole for inserting a screw that attaches the second hinge section 20 to the sleeve mirror 540L. The screw hole 214 is a hole for inserting a screw that attaches the motion transmission section 22. The second hinge body 21 is not limited to the shape shown in Figures 1 and 2, etc., as long as it has the above functions.

[0036] The motion transmitting unit 22 transmits the closing motion of the sleeve mirror 540R to the first hinge unit 10. Specifically, the motion transmitting unit 22 has, for example, a convex cam shape that protrudes toward the first hinge unit 10, i.e., toward the closing direction of the opening and closing direction.

[0037] The first hinge portion 10 is attached to a first member, specifically, for example, a panel 530R of the makeup mirror unit 500. The first hinge portion 10 has a rotating portion 11, an elastic member 12, a slider 13, a damper 14, a gear portion 15, a base portion 16, and a casing 17.

[0038] The base portion 16 has a top surface portion 161, a base portion main body 162, a hinge shaft hole 163, and a rotation shaft support hole 166. The base portion 16 has the top surface portion 161 provided on the upper end portion of the flat plate-shaped base portion main body 162, and is formed in an L-shape or a nearly L-shape when viewed from the side.

[0039] The hinge shaft hole 163 and the rotation shaft support hole 166 are through holes provided in the top surface portion 161. The above-mentioned shaft pin 164 and shaft bush 165 are attached to the hinge shaft hole 163 and the shaft hole 212 of the second hinge portion 20. The shaft bush 165 is inserted (press-fitted) into the hinge shaft hole 163. The shaft pin 164 is inserted into the shaft hole 212 of the second hinge portion 20, and its tip portion is crimped by the shaft bush 165. In this manner, the second hinge portion 20 is rotatably attached to the first hinge portion 10. The rotation shaft 111 of the rotating portion 11 is rotatably inserted into the rotation shaft support hole 166. The mounting screw 167 is fastened to the casing 17, thereby fixing the casing 17 to the base portion 16.

[0040] The rotating part 11 has a rotating shaft 111 , an outer circumferential part 112 , and a gear part 15 .

[0041] Fig. 5 is a partially transparent plan view showing the hinge device 1 in the open state, and Fig. 6 is a partially transparent plan view showing the hinge device 1 operating in the closing direction.

[0042] The rotary shaft 111 is a shaft that enables the rotating unit 11 to rotate, and its axis A2 is disposed in the vertical direction. As shown in Figures 1 and 2, in the rotating unit 11, the rotary shaft 111 is rotatably supported in the rotary shaft support hole 166 of the base unit 16. Therefore, the rotating unit 11 rotates around the rotary shaft 111 due to the closing movement of the sleeve mirror 540R in the direction of arrow ab transmitted from the motion transmitting unit 22.

[0043] 5 and 6, in the rotating part 11, the outer circumferential part 112 is provided so as to protrude radially outward from the rotating shaft 111. The outer circumferential part 112 has a first contact part 113 and a second contact part 114.

[0044] The first contact portion 113 is provided on the outer circumferential portion 112. The first contact portion 113 is configured to be able to come into contact with the motion transmitting portion 22. Specifically, the first contact portion 113 is formed in a concave shape so as to be able to receive the motion transmitting portion 22 formed in a convex shape so as to protrude from the second hinge body 21 when the second hinge portion 20 is rotated in the closing direction toward the first hinge portion 10 and closed.

[0045] The second contact portion 114 is provided at a different position from the first contact portion 113 in the circumferential direction of the outer circumferential portion 112. The second contact portion 114 is configured to be able to come into contact with the slider 13. Specifically, the second contact portion 114 comes into contact with the slider 13 in the vicinity of a center line C1 in the y direction on the contact surface portion 131 of the slider 13, for example.

[0046] The gear unit 15 is provided on the rotating part 11 below the outer circumferential part 112. Therefore, the gear unit 15 is rotatable around the rotation shaft 111. The gear unit 15 has teeth that protrude radially outward from the rotation shaft 111 and that mesh with a damper gear 142 that is provided on the rotation shaft of the damper 14.

[0047] As shown in FIG. 5 , the elastic member 12 is provided to the side of the rotating part 11, for example, inside the elastic member accommodating portion 132 of the right slider 13. The elastic member 12 is, for example, a coil spring. The slider 13 is interposed between the elastic member 12 and the motion transmitting part 22 and the rotating part 11. The elastic member 12 applies a biasing force to the motion transmitting part 22 in the closing direction, for example, via the slider 13 and the rotating part 11. Specifically, the elastic member 12 exerts an elastic force in the leftward direction indicated by arrow e, and applies a biasing force to the slider 13 in the direction indicated by arrow e. The slider 13 also applies a biasing force to the rotating part 11 when the contact surface portion 131 comes into contact with the second contact portion 114.

[0048] 6, when the second hinge portion 20 moves in the closing direction indicated by the arrow a and the motion transmission portion 22 comes into contact with the first contact portion 113, the rotating portion 11 rotates about the rotation axis 111 in the direction of the arrow c. As the rotating portion 11 rotates, the contact position between the second contact portion 114 and the contact surface portion 131 moves downward from the center line C1 in the y direction of the contact surface portion 131, that is, in the -y direction. At this time, because a biasing force in the e direction is applied to the slider 13, this biasing force causes the rotating portion 11 to further rotate in the c direction, and the biasing force is transmitted to the second hinge portion 20 via the motion transmission portion 22, thereby performing a closer function that assists the rotation of the second hinge portion 20 in the closing direction.

[0049] FIG. 7 is a partially enlarged plan view showing a rotating portion and a damper in the hinge device 1 that operates in the closing direction.

[0050] 2 and 7, the damper 14 has a damper body 141 and a damper gear 142. The damper body 141 is, for example, a rotary damper that damps the rotational force of a rotating shaft. The damper gear 142 is attached to the rotating shaft of the damper body 141. The damper gear 142 meshes with the gear portion 15 of the rotating portion 11.

[0051] As shown in FIG. 7 , when the second hinge portion 20 moves in the closing direction indicated by arrow a and the motion transmission portion 22 comes into contact with the first contact portion 113, the gear portion 15 provided on the rotating portion 11 rotates in the direction of arrow c around the rotation axis 111. As the gear portion 15 rotates, the rotation axes of the meshed damper gear 142 and damper main body 141 rotate in the direction of arrow f around axis A3. The damper main body 141 damps the rotational force in the direction f. The damping force of the damper main body 141 is transmitted to the second hinge portion 20 via the damper gear 142, the gear portion 15, the first contact portion 113, and the motion transmission portion 22. In other words, the damper 14 performs a damping function that damps the closing motion of the second hinge portion 20 via the gear portion 15 and the motion transmission portion 22.

[0052] The casing 17 is attached to the base portion 16 and houses components such as the rotating portion 11, the elastic member 12, the slider 13, the damper 14, and the gear portion 15. The casing 17 has an opening around the first contact portion 113 so that the first contact portion 113 of the rotating portion 11 can come into contact with the motion transmission portion 22 of the second hinge portion 20.

[0053] 8 is a perspective view of the hinge device 1RL according to the first embodiment of the present invention, in which the hinge device 1RL is upside down from the state in which it is attached to the makeup mirror unit 500 shown in FIGS.

[0054] The hinge device 1RL is attached to the underside of the side mirror 540R in the makeup mirror unit 500. The side mirror 540R is rotatably attached to the panel 530R by the hinge device 1RL. The hinge device 1RL differs from the similar components of the hinge device 1 shown in FIG. 1 in the shapes of the base portion 16RL and casing 17RL of the first hinge portion 10RL and the second hinge body 21RL of the second hinge portion 20RL. The hinge device 1RL has the same configuration and performs the same operation as the hinge device 1 described above, except for the differences in the shapes of the first hinge portion 10RL and the second hinge portion 20RL due to the difference in the attachment positions relative to the panel 530R, and the attachment position and rotation direction of the second hinge portion 20 relative to the first hinge portion 10RL. 3. Other embodiments [Second embodiment] A hinge device 1B according to a second embodiment of the present invention will be described below. Only the configurations that differ from the hinge device 1 according to the first embodiment will be described below.

[0055] Fig. 9 is a perspective view of a hinge device 1B according to a second embodiment of the present invention, and Fig. 10 is a partially see-through plan view showing the hinge device 1B in an open state.

[0056] 9 and 10, like the hinge device 1, the upper side of the right-hand side mirror 540R as viewed from the primary mirror 520 is rotatably attached to the panel 530R. Hinge device 1B differs from the previously described hinge device 1 mainly in the configuration of the motion transmission part 22B of the second hinge part 20B and the rotation part 11B that receives the motion of the motion transmission part 22B.

[0057] The motion transmitting unit 22B has a first rod 222, a connecting pin 223, and a second rod 224. The first rod 222 is rotatably attached to a pin 225. The second rod 224 is attached to the rotating unit 11B so as to be rotatable together with the rotation shaft 111B. The connecting pin 223 connects the first rod 222 and the second rod 224. In other words, the motion transmitting unit 22B is a link mechanism connected to the rotating unit 11B.

[0058] The rotating part 11B has a cam-shaped outer circumferential part 112B, which is in contact with a contact surface part 131 of the slider 13. Therefore, similar to the hinge device 1, the elastic member 12 applies a biasing force in the closing direction to the motion transmitting part 22B via the slider 13 and the rotating part 11B. The elastic member 12 exerts an elastic force in the direction of arrow e to the left, and applies a biasing force to the slider 13 in the direction of arrow e. The slider 13 also applies a biasing force to the rotating part 11B as the contact surface part 131 comes into contact with the outer circumferential part 112B.

[0059] In the hinge device 1B, when the second hinge portion 20B moves in the closing direction indicated by the arrow a, the motion transmitting portion 22B causes the rotating portion 11B to rotate in the direction of the arrow c around the rotation shaft 111B.

[0060] Rotation of rotating part 11B moves the contact position between cam-shaped outer circumferential part 112B and contact surface part 131. At this time, since a biasing force in the direction e is applied to slider 13, this biasing force causes rotating part 11B to further rotate in the direction c, and the biasing force is transmitted to second hinge part 20B via motion transmission part 22B, thereby exerting a closer function that assists the rotational movement of second hinge part 20B in the closing direction.

[0061] Furthermore, the rotating part 11B is configured so that the rotating shaft 111B can rotate together with the rotating shaft of the damper body 141 of the damper 14. Therefore, when the motion transmitting part 22B causes the rotating part 11B to rotate around the rotating shaft 111B in the direction of arrow c, the rotational force of the rotating shaft 111B is damped by the damper body 141. The damping force of the damper body 141 is transmitted to the second hinge part 20B via the rotating part 11B and the motion transmitting part 22B. In other words, the damper 14 exhibits a damping function that damps the closing operation of the second hinge part 20B via the rotating part 11B and the motion transmitting part 22B.

[0062] [Third embodiment] A hinge device 1C according to a third embodiment of the present invention will be described below. Only the configurations that differ from the hinge devices 1 and 1B according to the first and second embodiments will be described below.

[0063] FIG. 11 is a perspective view of a hinge device 1C according to the third embodiment of the present invention.

[0064] 11, like the hinge devices 1 and 1B, the upper side of the right-hand side mirror 540R (as viewed from the front) is rotatably attached to the panel 530R. The hinge device 1C differs from the previously described hinge devices 1 and 1B mainly in that the second hinge portion 20C has a motion transmission portion 22C, and that the rotating portion that receives the motion of the motion transmission portion 22C is a damper gear 142.

[0065] The motion transmitting portion 22C has a slider contact portion 226 and a gear portion 227. The slider contact portion 226 is formed so as to be able to come into contact with the slider 13 of the first hinge portion 10C, and transmits the closing motion of the sleeve mirror 540R.

[0066] The slider contact portion 226 has a convex cam shape that protrudes toward the first hinge portion 10C, i.e., toward the closing direction of the opening and closing direction. Due to this shape, the contact surface portion 131 of the slider 13 can come into contact with the motion transmitting portion 22C when the second hinge portion 20C moves in the closing direction.

[0067] The gear part 227 is an arc-shaped gear that protrudes toward the first hinge part 10C, i.e., toward the closing direction of the opening and closing directions. Due to this shape, the gear part 227 can mesh with the damper gear 142 of the first hinge part 10 when the second hinge part 20C moves in the closing direction.

[0068] In hinge device 1C, second hinge portion 20C moves in the closing direction, and first slider contact portion 226 of motion transmission portion 22C abuts against engaging portion 133 that is engaged with engaging groove 171 of casing 17 of slider 13, causing engaging portion 133 to move in the -z direction and disengage slider 13 from casing 17. Because a biasing force in the left direction is applied to slider 13, this biasing force presses slider contact portion 226, causing second hinge portion 20C to rotate further in the closing direction, thereby exerting a closer function that assists the rotational movement of second hinge portion 20C in the closing direction.

[0069] Furthermore, when the second hinge portion 20C moves in the closing direction and the gear portion 227 meshes with the damper gear 142, the damper gear 142 rotates. As the damper gear 142 rotates, the rotation axis of the damper main body 141 rotates, damping the rotational force. The damping force of the damper main body 141 is transmitted to the second hinge portion 20C via the damper gear 142 and the gear portion 227. In other words, the damper 14C exerts a damping function that damps the closing operation of the second hinge portion 20C via the operation transmission portion 22C.

[0070] <Action and effect> In the hinge device 1, 1B, 1C, the second hinge portion 20, 20B, 20C attached to the second member such as the side mirror 540R has a motion transmission portion 22, 22B, 22C that transmits the closing motion to the first hinge portion. The first hinge portion 10, 10B, 10C attached to the first member such as the panel 530R has a rotating portion 11, 11B, 11C that rotates around a rotating shaft 111, 111B, 111C, an elastic member 12 that applies a biasing force to the motion transmission portion 22, 22B, 22C, a slider 13, and a damper 14 that damps the closing motion via the motion transmission portion 22, 22B, 22C.

[0071] According to the above configuration, by providing components that perform the closer function and the damper function to the first hinge portion 10, 10B, 10C attached to the first member side, which has a relatively large dimensional margin in the thickness direction, it is possible to reduce the number of components provided to the second hinge portion 20, 20B, 20C attached to the mirror surface side of the sleeve mirror 540R.

[0072] In other words, the hinge devices 1, 1B, and 1C described above can provide a compact configuration while being equipped with a closer function and a damper function. Also, the hinge devices 1, 1B, and 1C described above can be attached to the side mirror 540R without being exposed.

[0073] In addition, those skilled in the art can appropriately modify the switching device of the present invention in accordance with conventionally known knowledge. As long as such modifications still include the configuration of the present invention, they are of course included in the scope of the present invention. [Explanation of symbols]
