DETAILED DESCRIPTION OF THE INVENTION
[0010] The opening / closing device 100 shown in FIGS. 1 to 7 will be described. The opening / closing device 100 is a hinge that connects one member of two members to the other member in an openable / closable manner. A base member and a rotating member are rotatably provided, and the rotating member rotates with respect to the base member to perform an opening / closing operation. The opening / closing device 100 is used, for example, in OA devices such as scanners, fax machines, copiers, or multifunction devices, automobiles, toilet seats, or various electronic devices such as rice cookers. As the opening / closing device 100 connects one member of two members to the other member in an openable / closable manner, for example, there are a door portion rotatably connected to the main body of a printer, a document pressing device rotatably connected to the main body of a multifunction device, a display rotatably connected to a stand, a toilet seat rotatably connected to a toilet seat, a bonnet rotatably connected to the vehicle body of an automobile, and the like.
[0011] When the rotating member is closed with respect to the base member, the rotation angle θ of the rotating member is set to 0°, and the rotation angle θ of the rotating member is defined such that the rotation angle θ increases when the rotating member rotates in the opening direction. Also, hereinafter, for convenience, the opening / closing device 100 will be described with reference to the vertical direction, front-rear direction, and left-right direction of the opening / closing device 100 when the rotating member is closed with respect to the base member.
[0012] As shown in FIGS. 1 to 6, the opening / closing device 100 includes a lower fixing member 10, an intermediate member 20, an upper fixing member 30, a slide member having a first slider 40 and a second slider 50, a spring member 60, a damper 62, a first rotation shaft 71, a second rotation shaft 72, a first pressure receiving member 75, and a second pressure receiving member 76. An embodiment of the base member according to the present invention includes the lower fixing member 10, the first rotation shaft 71, and the first pressure receiving member 75. An embodiment of the rotating member according to the present invention includes the intermediate member 20, the upper fixing member 30, the slide member (the first slider 40 and the second slider 50), the spring member 60, the damper 62, the second rotation shaft 72, and the second pressure receiving member 76.
[0013] The lower fixing member 10 is formed by appropriately bending a single metal plate. The lower fixing member 10 includes a bottom plate 11, left and right side plates 12·12, and a back plate 13.
[0014] The bottom plate 11 of the lower fixing member 10 is a plate-like member that constitutes the lower part of the lower fixing member 10. The shape of the bottom plate 11 is generally rectangular and slightly longer in the front-rear direction in plan view. The side plates 12·12 of the lower fixing member 10 are plate-like members that constitute the left and right side portions of the lower fixing member 10. The lower end portions of the side plates 12·12 are connected to the end portions of the bottom plate 11. Through holes for inserting the first rotation shaft 71 are opened at the rear upper end portions of the side plates 12·12. Through holes for inserting the first pressure receiving member 75 are opened at the front upper end portions of the side plates 12·12. The back plate 13 of the lower fixing member 10 is a plate-like member that constitutes the rear part of the lower fixing member 10. The shape of the back plate 13 is generally rectangular and slightly longer in the left-right direction in front view. The lower end portion of the back plate 13 is connected to the rear end portion of the bottom plate 11.
[0015] The intermediate member 20 is an embodiment of the first rotating member according to the present invention. The intermediate member 20 is formed by appropriately bending a single metal plate. The intermediate member 20 includes a top plate 21 and left and right side plates 22·22. In the intermediate member 20, the top plate 21 is disposed above the side plates 22·22, and the side plates 22·22 are bent downward from both left and right sides of the top plate 21, so that it is configured in a substantially U-shape when viewed from the front in the closed state of the opening / closing device 100. The intermediate member 20 is configured in a box shape with the lower left and right central portions opened by bending the lower end portions of the side plates 22·22 so as to extend toward the left and right central sides. The intermediate member 20 is rotatably supported by the lower fixing member 10 via the first rotating shaft 71 in a state where the first slider 40, the second slider 50, the spring member 60, the damper 62, etc. are accommodated. Through holes for inserting the first rotating shaft 71 are opened at the rear portions of the side plates 22·22 of the intermediate member 20. Through holes for inserting the second rotating shaft 72 are opened at the front end portions of the side plates 22·22.
[0016] The first rotating shaft 71 is a member having a substantially cylindrical shape. The first rotating shaft 71 is inserted into the through holes at the rear portions of the side plates 22·22 of the intermediate member 20 and the through holes at the upper rear end portions of the side plates 12·12 of the lower fixing member 10. The intermediate member 20 is rotatably connected to the lower fixing member 10 via the first rotating shaft 71.
[0017] The upper fixing member 30 is an embodiment of the second rotating member according to the present invention. The upper fixing member 30 is formed by appropriately bending a single metal plate. The upper fixing member 30 includes a top plate 31 and left and right side plates 32·32. In the upper fixing member 30, the top plate 31 is disposed above the side plates 32·32, and the side plates 32·32 are bent downward from both left and right sides of the top plate 31, so that it is configured in a substantially U-shape when viewed from the front in the closed state of the opening / closing device 100. The upper fixing member 30 is rotatably supported by the intermediate member 20 via the second rotating shaft 72. The upper fixing member 30 is fixed to the other member of the two members. Through holes for inserting the second rotating shaft 72 are opened at the upper front end portions of the side plates 32·32. Through holes for attaching the second pressure receiving member 76 are opened at the lower front end portions of the side plates 32·32.
[0018] The second rotating shaft 72 is a member generally in a cylindrical shape. The second rotating shaft 72 is inserted into the through holes at the front upper ends of the side plates 32·32 of the upper fixing member 30 and the through holes at the front parts of the side plates 12·12 of the intermediate member 20. The upper fixing member 30 is rotatably connected to the intermediate member 20 via the second rotating shaft 72.
[0019] The first pressure receiving member 75 is made of a metal material and is configured in a pin shape. The first pressure receiving member 75 is inserted into the through hole at the front upper end of the side plates 12·12 and fixed to the lower fixing member 10 in front of the first rotating shaft 71. The surface of the first pressure receiving member 75 on the side of the first slider 40 is formed as a curved surface and contacts the first cam portion 41 of the first slider 40. Note that the first pressure receiving member 75 is not limited to a pin shape, and can also be configured in other forms such as a block shape or by bending a plate-shaped member.
[0020] The second pressure receiving member 76 is an embodiment of the pressure receiving member according to the present invention. The second pressure receiving member 76 is configured in a pin shape. The second pressure receiving member 76 is inserted into the through hole at the front lower end of the side plates 32·32 and fixed to the upper fixing member 30. The surface of the second pressure receiving member 76 on the side of the second slider 50 contacts the second cam portion 51 of the second slider 50. Note that the second pressure receiving member 76 is not limited to a pin shape, and can also be configured in other forms such as a block shape or by bending a plate-shaped member.
[0021] The first slider 40 is made of a resin material. The front of the first slider 40 is open and it has a bottom at the rear. The first slider 40 is provided with a first cam portion 41 formed by a curved surface on the rear surface of the bottom. The first slider 40 is configured to contact the first pressure receiving member 75 at the rear surface of the first cam portion 41. A spring receiving hole for accommodating the rear end portion of the spring member 60 is formed in the first slider 40. The first slider 40 is slidably accommodated in the rear part inside the intermediate member 20 in the front-rear direction. The first slider 40 is movable in a direction approaching and separating from the first pressure receiving member 75 and is pressed toward the first pressure receiving member 75 side so that the first cam portion 41 contacts the first pressure receiving member 75. A lubricant such as grease is applied to the contact portion between the first cam portion 41 and the first pressure receiving member 75 to suppress wear.
[0022] The second slider 50 is made of a resin material. The rear of the second slider 50 is open and it has a bottom at the front. The second slider 50 is provided with a second cam portion 51 on the front surface of the bottom. The second slider 50 is configured to contact the second pressure receiving member 76 at the second cam portion 51. A spring receiving hole for accommodating the front end portion of the spring member 60 is formed in the second slider 50. The second slider 50 is slidably accommodated in the rear part inside the intermediate member 20 in the front-rear direction. The second slider 50 is movable in a direction approaching and separating from the second pressure receiving member 76 and is pressed toward the second pressure receiving member 76 side so that the second cam portion 51 contacts the second pressure receiving member 76. A lubricant is applied to the contact portion between the second cam portion 51 and the second pressure receiving member 76 to suppress wear.
[0023] The state in which the rotating member is closest to the base member is defined as the "closed state" of the rotating member. The closed state refers to the state where the rotation angle θ from the closed state of the rotating member with respect to the base member is 0° (see FIGS. 1 to 2). Also, the state in which the rotating member is separated from the base member is defined as the "open state" of the rotating member. The open state refers to the state that satisfies the relationship 0° < θ < 95° for the rotation angle θ (see FIGS. 3 to 4). Note that the closed state of the rotating member is not limited to the rotation angle θ being 0°, and the open state of the rotating member is not limited to satisfying the relationship 0° < θ < 95° for the rotation angle θ. Regarding the rotation angle θ of the closed state of the rotating member or the rotation angle θ of the open state of the rotating member, it can be appropriately set to other angles according to specifications, applications, etc.
[0024] As shown in FIGS. 5 to 6, a lift state can be set in which the intermediate member 20 is open with respect to the lower fixing member 10 and the upper fixing member 30 is open with respect to the intermediate member 20.
[0025] The spring member 60 is composed of a metal coil spring. The spring member 60 is housed in the spring receiving holes of the first slider 40 and the second slider 50 inside the intermediate member 20. The rear end portion of the spring member 60 is inserted into the spring receiving hole formed in the first slider 40 and contacts the bottom surface of the spring receiving hole. Also, the front end portion of the spring member 60 is inserted into the spring receiving hole formed in the second slider 50 and contacts the bottom surface of the spring receiving hole.
[0026] Due to the elastic force of the spring member 60, the first slider 40 is pressed in a direction approaching the first pressure receiving member 75 in the longitudinal direction of the intermediate member 20, and the second slider 50 is pressed in a direction approaching the second pressure receiving member 76 in the longitudinal direction of the intermediate member 20.
[0027] The stopper 61 is a metal member having a substantially rectangular shape when viewed from the rear, and is fixed to the back plate 13 of the lower fixing member 10 by screws or the like. The stopper 61 is disposed on the rear surface of the back plate 13 of the lower fixing member 10. The upper end of the stopper 61 is located above the upper end of the back plate 13 of the lower fixing member 10. The stopper 61 restricts the rotation of the upper fixing member 30 in the opening direction by the upper end portion of the stopper 61 coming into contact with the top plate 31 of the upper fixing member 30 rotated in the opening direction. The stopper 61 is set such that the upper end portion of the stopper 61 comes into contact with the upper fixing member 30 when the rotation angle θ of the rotating member is 60°. Note that, instead of providing the stopper 61, a configuration may be adopted in which the back plate 13 of the lower fixing member 10 comes into contact with the upper fixing member 30 rotated in the opening direction to restrict the rotation of the upper fixing member 30 in the opening direction.
[0028] The damper 62 is housed in the spring receiving holes of the first slider 40 and the second slider 50. The main body portion of the damper 62 is fixed to the bottom of the first slider 40, and its tip projects toward the second rotation shaft 72 side. The damper 62 generates a reaction force when the tip is pressed by the bottom of the second slider 50. For this reason, the reaction force reduces the speed at which the first slider 40 and the second slider 50 move, and a buffering effect by the damper 62 occurs. The damper 62 is constituted by a general fluid damper.
[0029] When the rotating member is in the closed state, the first cam portion 41 of the first slider 40 comes into contact with the first pressure receiving member 75, and the second cam portion 51 of the second slider 50 comes into contact with the second pressure receiving member 76. In such a state, the first slider 40 is pressed by the elastic force of the spring member 60, and the intermediate member 20 is pressed so as to rotate in the opening direction with respect to the lower fixing member 10. Further, the second slider 50 is pressed by the elastic force of the spring member 60, and the upper fixing member 30 is pressed so as to rotate in the closing direction with respect to the intermediate member 20. At this time, the tip of the damper 62 is pressed by the bottom of the second slider 50 and is pushed into the main body portion side of the damper 62.
[0030] Also, even when the rotating member is in the open state, the first cam portion 41 of the first slider 40 contacts the first pressure receiving member 75, and the second cam portion 51 of the second slider 50 contacts the second pressure receiving member 76. In such a state, the first slider 40 is pressed by the elastic force of the spring member 60, and the intermediate member 20 is pressed to rotate in the opening direction with respect to the lower fixing member 10. Also, the second slider 50 is pressed by the elastic force of the spring member 60, and the upper fixing member 30 is pressed to rotate in the closing direction with respect to the intermediate member 20.
[0031] That is, regardless of the rotation angle θ of the rotating member, the first slider 40 is pressed toward the first pressure receiving member 75 so that the first cam portion 41 continuously contacts the first pressure receiving member 75 in both the closed state and the open state of the rotating member. In both the closed state and the open state of the rotating member, the first cam portion 41 of the first slider 40 contacts the first pressure receiving member 75, and the second cam portion 51 of the second slider 50 contacts the second pressure receiving member 76. Due to the elastic force of the spring member 60, the intermediate member 20 is pressed to rotate in the opening direction with respect to the lower fixing member 10, and the upper fixing member 30 is pressed to rotate in the closing direction with respect to the intermediate member 20.
[0032] When the rotating member is in the lifted state where the intermediate member 20 is open with respect to the lower fixing member 10 and the upper fixing member 30 is open with respect to the intermediate member 20, the first cam portion 41 of the first slider 40 contacts the first pressure receiving member 75, and the second cam portion 51 of the second slider 50 contacts the second pressure receiving member 76. In such a state, the first slider 40 is pressed by the elastic force of the spring member 60, and the intermediate member 20 is pressed to rotate in the opening direction with respect to the lower fixing member 10. Also, the second slider 50 is pressed by the elastic force of the spring member 60, and the upper fixing member 30 is pressed to rotate in the opening direction with respect to the intermediate member 20. At this time, the tip of the damper 62 is pressed by the bottom of the second slider 50 and is pushed into the main body portion side of the damper 62.
[0033] As shown in FIG. 4 or FIG. 6, when the upper fixing member 30 rotates in the opening direction with respect to the intermediate member 20, the second slider 50 is pressed by the second pressure receiving member 76 and moves in a direction away from the second pressure receiving member 76. When the upper fixing member 30 rotates in the closing direction with respect to the intermediate member 20, the second slider 50 is pressed by the spring member 60 and the damper 62 and moves in a direction approaching the second pressure receiving member 76. As shown in FIGS. 5 to 7, the second slider 50 includes an interference avoidance portion 53. The interference avoidance portion 53 avoids interference between the second slider 50 and the trailing edge portion of the external member 101 provided on the upper fixing member 30 when the upper fixing member 30 rotates in the opening direction with respect to the intermediate member 20. For example, in the case where the opening / closing device 100 is configured to rotatably connect a document pressing plate to the main body of the multifunction machine, the "external member 101 provided on the upper fixing member 30" is configured as a housing frame of the document pressing plate or the like. The housing frame is configured in a plate shape and is disposed so as to extend between the left and right side plates 32, 32 of the upper fixing member 30. The housing frame protrudes forward from the front lower ends of the side plates 32, 32 of the upper fixing member 30 in the closed state or the lifted state of the rotating member.
[0034] The second slider 50 is provided with a notch portion 54 configured as an interference avoidance portion 53. The notch portion 54 is notched such that a predetermined space is formed in a portion that interferes with the external member 101 of the second slider 50 on the rotation locus of the external member 101 when the upper fixing member 30 rotates with respect to the intermediate member 20. The notch portion 54 is formed at a boundary portion between the front portion and the lower portion of the second slider 50 in the closed state or the lifted state of the rotating member. The notch portion 54 is formed across the left and right of the second slider 50. The notch portion 54 is configured such that the boundary portion between the front portion and the lower portion of the second slider 50 in the closed state of the rotating member is notched in a substantially rectangular shape in a side view. The interference avoidance portion 53 of the second slider 50 avoids interference with the trailing edge portion of the external member 101 provided on the upper fixing member 30 when the upper fixing member 30 rotates in an opening direction with respect to the intermediate member 20 by forming the notch portion 54. Note that the notch portion 54 is not limited to such a configuration, and can be configured in an appropriate shape or formed at an appropriate location according to the specifications.
[0035] As described above, the notch portion 54 configured as the interference avoidance portion 53 of the second slider 50 is notched such that a predetermined space is formed in a portion that interferes with the external member 101 of the second slider 50 on the rotation locus of the external member 101 when the upper fixing member 30 rotates with respect to the intermediate member 20, thereby avoiding interference with the external member 101. Therefore, when the upper fixing member 30 rotates in an opening direction with respect to the intermediate member 20, interference between the second slider 50 and the external member 101 provided on the upper fixing member 30 can be avoided with a simple configuration.
[0036] As the upper fixing member 30 rotates in the opening and closing directions with respect to the intermediate member 20, the second slider 50 is pressed by the spring member 60, so that a part of the second cam portion 51 contacts the surface of the second pressure receiving member 76 and reciprocates along a direction orthogonal to the axial direction of the second rotation shaft 72 with respect to the surface of the second pressure receiving member 76.
[0037] The second cam portion 51 of the second slider 50 is configured as an interference avoidance portion 53. The second cam portion 51 has a portion that protrudes toward the second pressure receiving member 76 when the upper fixing member 30 is open with respect to the intermediate member 20, compared to a portion that contacts the second pressure receiving member 76 when the upper fixing member 30 is closed with respect to the intermediate member 20. The second cam portion 51 is configured to have a linear inclined surface that inclines forward, upward, backward, and downward in the closed state of the opening / closing device 100. The portion of the second cam portion 51 that contacts the second pressure receiving member 76 when the upper fixing member 30 is open with respect to the intermediate member 20 is configured to be thicker than the portion that contacts the second pressure receiving member 76 when the upper fixing member 30 is closed with respect to the intermediate member 20. By configuring the portion of the second cam portion 51 that contacts the second pressure receiving member 76 when the upper fixing member 30 is open with respect to the intermediate member 20 to be thicker, the interference avoidance portion 53 increases the amount of movement of the second slider 50 toward the first slider 40 when the upper fixing member 30 rotates with respect to the intermediate member 20. In this way, the interference avoidance portion 53 moves the second slider 50 toward the first slider 40 so that a predetermined space is formed in a portion where the external member 101 and the second slider 50 interfere on the rotation locus of the external member 101 when the upper fixing member 30 rotates with respect to the intermediate member 20. Note that the second cam portion 51 may be configured to have a curved inclined surface instead of having a linear inclined surface.
[0038] As described above, in the second slider 50, the portion where the upper fixing member 30 contacts the second pressure receiving member 76 in the open state with respect to the intermediate member 20 protrudes toward the second pressure receiving member 76 side compared to the portion where the upper fixing member 30 contacts the second pressure receiving member 76 in the closed state with respect to the intermediate member 20. In this way, the interference avoidance portion 53 of the second slider 50 moves the second slider 50 toward the first slider 40 side so that a predetermined space is formed in a portion where the external member 101 and the second slider 50 interfere on the rotation locus of the external member 101 when the upper fixing member 30 rotates with respect to the intermediate member 20. Therefore, when the upper fixing member 30 rotates with respect to the intermediate member 20, it is possible to avoid interference between the second slider 50 and the external member 101 provided on the upper fixing member 30 with a simple configuration.
[0039] Note that the opening / closing device 100 may be configured such that the lower fixing member 10 is not provided, and the first rotation shaft 71 is directly provided on a connection target such as the main body of an OA device, and the intermediate member 20 is rotatably provided on the connection target such as the main body of the OA device via the first rotation shaft 71. Further, the opening / closing device 100 may be configured such that the upper fixing member 30 is not provided, and the second rotation shaft 72 is directly provided on a connection target such as a document pressing device of an OA device, and the connection target such as the document pressing device of the OA device is rotatably provided on the intermediate member via the second rotation shaft 72.
