  However, in the conventional hinge structure, the first support portion is integrally formed on the trunk through box side, and the second support portion is integrally formed on the trunk through door side. Together, the man-hours required for processing increased, and the use of hinge pins naturally increased the number of parts.

  The present invention was developed in order to effectively solve the problems of such a conventional hinge structure. The invention according to claim 1 is a fixed plate attached to the support body side and a movable plate attached to the opening / closing body side. A pair of shafts protruding in the same direction on one of the fixed plate and the movable plate, and one spring receiver protruding in the opposite direction and facing one shaft A seat is formed, and on the other side, a pair of bearing portions into which the pair of shaft portions are fitted is formed, and a movable plate is opened between the one shaft portion fitted into the corresponding one bearing portion and the spring receiving seat. A spring member for biasing in the direction is mounted.

  According to the second aspect of the present invention, on the premise of the first aspect, a cover portion is integrally extended on either the fixed plate or the movable plate, and the outer periphery of the shaft portion, the spring seat or the bearing portion is formed by the cover portion. It is characterized by covering less than half.

  According to a third aspect of the present invention, on the premise of the first and second aspects, a damper means for controlling the rotation of the movable plate in the opening direction is provided, and the mounting groove is formed in the other bearing portion corresponding to the other shaft portion. And the damper means is detachably supported in the mounting groove.

  According to a fourth aspect of the present invention, on the premise of the first to third aspects, the assembly position of the fixed plate and the movable plate is a position rotated further in the closing direction than the fully closed position in the use range of the movable plate. It is characterized by being.

  According to a fifth aspect of the present invention, on the premise of the third aspect, the assembly position of the damper means with respect to the mounting groove is a position rotated further in the opening direction than the fully opened position in the use range of the movable plate. .

  Therefore, in the invention described in claim 1, since it is not necessary to assemble the fixed plate and the movable plate using the hinge pin, the number of parts increases as in the conventional case, and the number of assembling steps is great. Since the fixed plate is attached to the support side and the movable plate is attached to the opening / closing body side, it is not necessary to perform complicated processing on the support body and the opening / closing body.

  In the invention described in claim 2, since the cover portion covers less than half of the outer periphery of the shaft portion, the spring seat or the bearing portion, it is particularly preferable to prevent the assembly of the solid plate and the movable plate. It is possible to effectively prevent the spring member attached between the shaft portion and the spring seat from falling off.

  In the invention according to claim 3, since the damping means can apply a braking force to the rotation of the movable plate in the opening direction, there is no fear of the opening / closing body opening suddenly, and other bearing portions Since the damper means can be supported in the formed mounting groove, the support space for the damper means can be greatly reduced.

  In the invention according to claim 4, since the assembly position of the fixed plate and the movable plate is a position rotated further in the closing direction than the fully closed position in the use position of the movable plate, the movable plate is set. In addition, there is no concern that the connection between the fixed plate and the movable plate is released within the operating range in which the fully closed position and the fully open position are rotated.

  In the invention of claim 5, since the assembly position of the damper means with respect to the mounting groove is a position rotated further in the opening direction than the fully opened position in the use position of the movable plate, all the movable plates are set. There is no fear that the damper means will come out of the mounting groove within the operating range in which the closed position and the fully open position are rotated.

  The present invention presupposes a hinge structure including a fixed plate and a movable plate, and forms a pair of shaft portions protruding in the same direction on either the fixed plate or the movable plate, and protrudes in the opposite direction. One spring receiving seat that faces the shaft portion is formed, and on the other side, a pair of bearing portions into which the pair of shaft portions are inserted is formed, and the one shaft portion that is inserted into the corresponding one bearing portion. By attaching a spring member that urges the movable plate in the opening direction between the spring receiving seat and the spring receiving seat, it is not necessary to assemble the fixed plate and the movable plate using a hinge pin.

  Hereinafter, the hinge structure according to the embodiment will be described in detail based on a preferred embodiment illustrated in the drawings. It was developed for use.

  Specifically, as shown in FIG. 1, the hinge structure according to the present embodiment includes a fixed plate 1 attached to a trunk through box side as a support and a movable plate attached to a trunk through door side as an opening / closing body. As shown in FIG. 2, two flange pieces 3a and 3b are integrally extended from the base 1a at a predetermined interval to the former fixing plate 1, A pair of shaft portions 4 and 5 having different sizes projecting in the same direction are integrally formed on one side surface of the flange pieces 3a and 3b, and a large shaft portion 4 is formed on the other side surface of the flange piece 3b in which the small shaft portion 5 is formed. A single spring receiving seat 6 facing each other is integrally formed, and a torsion coil spring 7 serving as a spring member for elastically biasing the movable plate 2 in the opening direction is mounted between the spring receiving seat 6 and the large shaft portion 4. It has a configuration.

  In addition to this, a bifurcated elastic claw 9 that holds the protrusion 8a of the damper means 8 that controls the rotation of the movable plate 2 in the opening direction is integrally formed on one end portion side of the fixed plate 1, A first cover portion 11 having an arcuate shape is integrally formed by interposing a slit 10 between the elastic claw 9 and the flange piece 3b on which the small shaft portion 5 is formed, and the small shaft portion 5 is formed. A second cover portion 12 having a circular arc shape is integrally extended between the flange piece 3b and the flange piece 3a formed with the large shaft portion 4 with a slit 10 interposed therebetween. The first and second cover portions 11 and 12 are set to have a dimension that covers less than half of the outer periphery of the pair of shaft portions 4 and 5 and one spring receiving seat 6.

  For the latter movable plate 2, as shown in FIG. 3, a large shaft portion 4 and a small shaft portion 5 are individually provided on the side edges of the base 2 a corresponding to the shaft portions 4 and 5 and the spring seat 6. A pair of bearing portions 13 and 14 that are fitted to each other are erected integrally with a certain interval, and the shaft portions 4 and 5 that correspond to the respective bearing portions 13 and 14 are fitted, whereby the fixed plate 1 and the movable plate 1 are movable. It has the structure connected with the board 2 so that rotation is possible. A mounting groove 15 that supports the rib wall 8b provided on the rotating shaft of the damper means 8 is formed on one side surface of the bearing portion 14 into which the small shaft portion 5 is inserted. To do.

  In this embodiment, when the fixed plate 1 and the movable plate 2 are assembled to be rotatable, the assembly position X is set to the normal use range A of the movable plate 2 as shown in FIG. As a result, the assembled state of the fixed plate 1 and the movable plate 2 is erroneously released within the operating range in which the movable plate 2 is rotated. We are actively adopting a configuration that prevents this.

When the damper means 8 is supported by the mounting groove 15 and the elastic claw 9 or released from the support, the assembly position Y is set to the fully open position in the normal use range A of the movable plate 2 as shown in FIG. In addition, a configuration that prevents the damper means 8 from being detached from the mounting groove 15 and the elastic claw 9 within the range of use in which the movable plate 2 is rotated is adopted in addition to the position C in the opening direction. ing.

  Therefore, when assembling the hinge device according to the present embodiment, first, the slits of the first and second cover portions 11 and 12 are set at the assembly position X that is further rotated in the closing direction than the above-described fully closed position B. 10, the shafts 4 and 5 of the fixed plate 1 are fitted into the corresponding bearings 13 and 14 of the movable plate 2 while relatively sliding the fixed plate 1 and the movable plate 2. As shown in FIG. 4, the fixed plate 1 and the movable plate 2 can be pivotably assembled without using any conventional hinge pin, so that the movable plate 2 is now rotated further in the opening direction than the fully open position C. If the torsion coil spring 7 is mounted between the large shaft portion 4 and the spring seat 6 while the damper means 8 is supported by the mounting groove 15 and the elastic claw 9 by rotating to the assembled position Y, As shown in FIG. 5, the damper means 8 and the torsion coil The fact that the root 7 is housed in a compact. When the torsion coil spring 7 is attached, the torsion coil spring 7 is attached while compressing the entire length thereof to prevent the torsion coil spring 7 itself from falling off and to prevent unnecessary rattling.

  Therefore, finally, as shown in FIG. 6, if the damper cover 16 is put on the outer periphery of the damper means 8 and at the same time the spring cover 17 is put on the outer periphery of the torsion coil spring 7, the hinge structure can be simplified. In particular, in this case, as shown in the figure, a pair of restricting claws 16 a provided on the damper cover 16 are provided with a pair of elastic claws 9 that support the protrusions 8 a of the damper means 8. Therefore, the damper cover 16 can be prevented from inadvertently dropping off during use even with the damper cover 16, but the outer periphery of the damper means 8 is less than half of that, but the first of the first circular arc shape. Since it is also covered with the cover part 11, it will never fall out between the bearing part 14 and the elastic claw 9 during use.

  Further, the torsion coil spring 7 also has no fear of being accidentally dropped from the shaft portion 4 and the spring seat 6 by the spring cover 17, but in this case as well, the outer periphery of the torsion coil spring 7 is less than half of that. However, since it is also covered by the second cover portion 12 having an arc shape, it will never fall out between the shaft portion 4 and the spring seat 6 during use.

  Therefore, in actual use, although not specifically illustrated, the fixed plate 1 is attached to the trunk through box side that is the support body, and the movable plate 2 is attached to the trunk through door side that is the opening and closing body. If the trunk through door is locked against the spring pressure of the torsion coil spring 7 on the trunk through box side, the communication window defined between the rear seat and the trunk room of the automobile is closed, so the normal use of the rear seat Is guaranteed. In this state, the trunk through door is locked at the fully closed position B in the use range A as the movable plate 2 rotates, so that the fixed plate 1 and the movable plate 2 are locked. It does not rotate to the assembly position X from which the assembly is removed.

When a long ski or the like is mounted in the vehicle compartment from the trunk room through the communication window, when the trunk through door is unlocked, the trunk through door is immediately opened in the opening direction by the spring pressure of the torsion coil spring 7. In this case, the braking force of the damper means 8 works, and the trunk through door slowly rotates to completely open the communication window. It is possible to mount a ski board. In this state, the trunk through door rotates to the fully open position C in the use range A as the movable plate 2 rotates, so that the support position of the damper means 8 can be released. It does not rotate to Y.

  The hinge structure according to the present invention makes it unnecessary to use a hinge pin, and can reduce the number of parts and the number of assembling steps. If it is used for a trunk through door or the like, it is very convenient.
