  Since the conventional hinge 100 is configured as described above, there is a problem that the L-shaped plate 102 has a wide lateral width W and requires space. In the case of a ceiling-mounted in-vehicle electronic device in which the chassis 2 is fixed to the ceiling of a vehicle or the like, there are few restrictions on the lateral width. Is desired.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a positioning structure with good workability while reducing the size of the hinge.

In the hinge positioning structure according to the present invention, the fixed body has a projecting piece for screwing the plate, a first notch groove formed inward from the edge of the projecting piece, and a closing of the first notch groove. And a second notch groove formed inwardly from the edge of the protruding piece on the circumference centered on the end on the other side, and the plate is slidable in the first notch groove. When the projection is provided with a second projection that can slide in the second notch groove, and the hinge is fixed to the chassis, the first projection slides in the first notch groove and closes to the end. Abutting against it, it becomes the rotation fulcrum of the plate, and when the plate rotates, the second protrusion slides into the second notch groove and hits the closed end, and the first protrusion fits into the first notch groove. At the same time, the second projection fits into the second notch groove to position the hinge relative to the fixed body. A structure for determining the first cutout groove is obtained by near the center of gravity of the movable member from the second notched groove, as formed in a direction crossing the opening and closing direction of the closing body.

  According to the present invention, since the protrusion is provided on the fixed body and the plate is screwed, a flat plate can be used and the hinge can be downsized. Further, when the plate is fixed to the fixed body, the hinge is positioned by fitting the first notch groove and the first protrusion and fitting the second notch groove and the second protrusion. Furthermore, since the first notch groove and the second notch groove guide the movement of the plate, workability is good.

  FIG. 3 is a plan view showing the configuration of the plate 12 and the protruding piece 17. 2 and 3, the short direction of the monitor 1 and the chassis 2 is X, the longitudinal direction is Y, and the direction orthogonal to X and Y is Z. A first notch groove 18 extending in the X direction from the edge of the projecting piece 17 is formed in the projecting piece 17 of the chassis 2. Further, a second portion extending in the Z direction inward from the edge of the projecting piece 17 on the circumference (indicated by a one-dot chain line in FIG. 3) around the end portion 18a on the closed side of the first cutout groove 18. A cutout groove 19 is formed. Furthermore, two screw holes 20 and 21 are formed in the projecting piece 17. The number and position of the screw holes may be arbitrary.

  The plate 12 is formed with a first protrusion 13 that is slidable in the first notch groove 18 and a second protrusion 14 that is slidable in the second notch groove 19. The first protrusion 13 and the first notch groove 18 are fitted to be positioned in the Z direction, and the second protrusion 14 and the second notch groove 19 are fitted to be positioned in the X direction.

Yes. The plate 12 is formed with two screw holes 15 and 16. The number and position of the screw holes may be arbitrary.

  The L-shaped plate 102 of FIG. 8 described above requires a lateral width W for fixing the L-shaped plate 102 to the chassis 2. On the other hand, since the plate 12 of the first embodiment is a flat plate, the lateral width can be reduced, and the hinge 10 can be downsized.

Next, the attachment procedure of the hinge 10 is demonstrated using FIG.
The operator first fixes the monitor 1 to one end side of the shaft 11 and attaches the plate 12 to the other end side so as to be rotatable. Thereafter, as shown in FIG. 4A, the operator slides the first protrusion 13 of the plate 12 along the first notch groove 18 of the projecting piece 17 in the direction of the arrow B, It abuts against the end 18a. Subsequently, as shown in FIG. 4B, the operator uses the plate 12 as the direction of the arrow C, with the first protrusion 13 abutting against the closed end 18 a of the first notch groove 18 as a rotation fulcrum. Rotate to As a result, the second protrusion 14 fits in the first notch groove 18 and slides and hits the end 19a on the closed side. The first protrusion 13 fits in the first notch groove 18 and the second protrusion 14 fits in the second notch groove 19, whereby the X direction and the Z direction of the plate 12 are positioned. Finally, as shown in FIG. 4C, the operator fastens the screw 22 to the screw holes 15 and 20 and fastens the screw 23 to the screw holes 16 and 21 to fix the plate 12 and the projecting piece 17. . Thus, the first notch groove 18 guides the slide of the plate 12 and the second notch groove 19 guides the rotation of the plate 12, so that the assembling work is easy.

  When the screws 22 and 23 are fastened, the direction of the monitor 1 and the chassis 2 may be changed so that the surfaces of the plate 12 and the projecting piece 17 face upward so that the work can be easily performed. At this time, the center of gravity G of the monitor 1 is at a position away from the hinge 10, so it tries to open with its own weight. However, since the first notch groove 18 intersects the opening / closing direction of the monitor 1, the first protrusion 13 is restricted by the first notch groove 18 and the monitor 1 does not open. Therefore, workability is good.

  As described above, according to the first embodiment, the positioning structure of the hinge 10 includes the first notch groove 18 formed inward from the edge of the projecting piece 17 and the closed side of the first notch groove 18. A second notch groove 19 formed inward from the edge of the projecting piece 17 on the circumference centering on the end portion 18a, and a first protrusion of the plate 12 slidable in the first notch groove 18 13 and the second protrusion 14 of the plate 12 slidable in the second notch groove 19. When the hinge 10 is fixed to the chassis 2, the first protrusion 13 slides in the first notch groove 18 and abuts on the closed end 18 a to become a rotation fulcrum of the plate 12, and the plate 12 rotates. The second protrusion 14 slides in the second notch groove 19 and hits the end 19a on the closed side, the first protrusion 13 fits into the first notch groove 18 and the second protrusion 14 The hinge 10 is positioned with respect to the chassis 2 by fitting into the two notch grooves 19. Thus, since the projection piece 17 is provided in the chassis 2 and the plate 12 is screwed, the flat plate 12 can be used and the hinge 10 can be reduced in size. Moreover, since the 1st notch groove 18 and the 2nd notch groove 19 guide the motion of the plate 12, workability | operativity is good.

  Further, according to the first embodiment, the first notch groove 18 is formed closer to the center of gravity G of the monitor 1 than the second notch groove 19 and in a direction crossing the opening / closing direction of the monitor 1.
