  Next, the main part (hinge unit) and the related configuration of the present invention will be described with reference to FIGS.

  As shown in FIGS. 4 and 5, the housing body 21 has a front reinforcing plate 300 on the front side.

  The hinge unit 400 is attached and fixed to the front reinforcing plate 300. The lid 3 is supported by the hinge body 400 so that it can be opened and closed freely.

  As shown in FIGS. 6 to 9, the hinge unit 400 includes a hinge base 410 and a connecting hinge 450.

  The hinge base 410 includes an outer peripheral frame portion 415 having two vertical sides 411 and 412, an upper side 413 and a lower side 414, an intermediate support portion 416 protruding inward from the middle of one vertical side 411, and an upper side 413. An upper shaft support piece portion 417a, 417b provided to stand up; an intermediate shaft support piece portion 418a, 418b provided to stand up to the intermediate support portion 416; a lower shaft support piece portion 419a provided up to stand up to the lower side 414; 419b.

  The connection hinge 450 has two gripping portions 451 and 452 that grip the lid 3 at one end, and two support root portions 453 and 454 split at the other end.

  The connecting hinge 450 has a generally curved shape formed by bending a single steel plate except for the two gripping portions 451 and 452 and the two supporting root portions 453 and 454 that are divided into two forks at both ends.

  The two support root portions 453 and 454 of the connecting hinge 450 have root support piece portions 455a and 455b and root support piece portions 456a and 456b provided to stand.

  The base support piece portion of the connecting hinge 450 is placed between the upper side shaft support piece portions of the hinge base 410, and the pivot shaft 480 is inserted into the shaft holes of the upper side shaft support piece portion and the root support piece portion. Thereby, the connection hinge 450 and the hinge base 410 are rotatably connected.

  The hinge unit 400 is attached and fixed to the front reinforcing plate 300 of the housing body 21 as shown in FIGS. 3 and 4 by screws inserted into the screw through holes 420 of the hinge base 410 shown in FIGS. .

  Then, by attaching and fixing the lid body 3 to the two gripping portions 451 and 452 of the connecting hinge 450 using screws, the lid body 3 is supported by the housing body portion 21 so as to be opened and closed as shown in FIG. .

  Thus, the connecting hinge 450 of the hinge unit 400 is a single unit unlike the conventional (hinge unit having two separate connecting members), and has two gripping portions 451 and 452 and two supporting root portions at both ends. 453 and 454 are provided.

  For this reason, unlike the conventional one having two separate connecting members, the positional relationship between the two gripping portions 451 and 452 of the connecting hinge 450 and the lid 3 is uniquely determined. It is not necessary to adjust the position and the assembly is easy.

  Further, since the hinge base 410 has a single structure including an outer peripheral frame portion 415 having two vertical sides 411 and 412, an upper side 413 and a lower side 414, the positional relationship with the front reinforcing plate 300 is unambiguous. Therefore, it is not necessary to adjust the alignment when assembling, and it is easy to assemble.

  Further, the connecting hinge 450 has a single structure having two grip portions 451 and 452 and two support base portions 453 and 454 at both ends. For this reason, it is stronger than the conventional one (two separate connecting members), and the connection hinge 450 is not bent even if a somewhat excessive external force is applied to the lid 3, and malfunction does not occur. .

  Furthermore, the support structure for rotatably supporting the connecting hinge 450 on the hinge base 410 using the rotation shaft mandrel 480 is a two-stage support structure.

  That is, the support base portion 453 of the connection hinge 450 is between the upper side shaft support piece portion 417b of the upper side 413 and the intermediate shaft support piece portion 418a provided on the intermediate support portion 416, and the support root portion 454 of the connection hinge 450 is the intermediate support portion. The two-stage support structure is divided between an intermediate shaft support piece 418b and a lower shaft support piece 419a provided in 416.

  For this reason, it is stronger than the one-stage support structure, and even if a somewhat excessive external force is applied to the lid 3, the connecting hinge 450 is not bent and does not cause a malfunction.

  As shown in FIGS. 6 to 8, the stopper rod 500 is placed so as to be spanned over the upper side shaft support piece 417b, the intermediate shaft support piece 418a, the intermediate shaft support piece 418b, and the lower side shaft support piece 419a. It is burned.

  Then, the stopper rod 500 is attached and fixed to the hinge base 410 by screws inserted into the screw through holes 510 of the stopper rod 500. The stopper reinforcing member 511 is integrally formed so as to extend along the longitudinal direction of the stopper rod 500, and is bent in a hook shape with respect to the stopper rod 500.

  As shown in FIG. 8, the base support piece portions 455 a and 455 b and the base support piece portions 456 a and 456 b of the connection hinge 450 have a stopper portion 512 that comes into contact with the stopper rod 500. When the lid 3 is opened, the stopper portion 512 abuts against the stopper rod 500 and is restricted from being opened any further.

  Since the stopper portion 512 is provided using the base support piece portion of the connection hinge 450, the configuration is simplified. Further, since the stopper reinforcing member 511 is provided on the stopper rod 500, the stopper rod 500 is strong, and the opening of the lid 3 can be reliably restricted to a predetermined position.

  Further, bending claws 512 are provided at both ends of the stopper reinforcing member 511 so as to sandwich the upper side shaft support piece portion 417b, the intermediate shaft support piece portions 418a and 418b, and the lower side shaft support piece portion 419a.

  Therefore, the upper side shaft support piece portion 417b, the intermediate shaft support piece portions 418a and 418b, and the lower side shaft support piece portion 419a are reinforced, and the hinge unit can be sufficiently tolerated even if a somewhat excessive external force is applied to the lid 3. 3 smooth opening and closing is maintained.

  As shown in FIGS. 7, 9, and 10, the connecting hinge 450 includes an intermediate portion 457 having a flat shape along the pivot shaft 480 and both side portions 458 provided on both sides of the intermediate portion 457. . The both side portions 458 have an inclined shape that rises toward the end side.

  The reinforcing veins 459 are provided on both side portions 458. The reinforcing vein 459 formed so as to be continuous between the grip portions 451 and 452 and the support root portions 453 and 454 protrudes inward of the connecting hinge 450 having a curved shape.

  The reinforcing veins 459 provided so as to connect the grip portions 451 and 452 and the support base portions 453 and 454 exist separately on both sides of the connecting hinge with the intermediate portion 457 interposed therebetween.

  As described above, the connection hinge 450 has the reinforcing vein 459, so that the connection hinge 450 is reinforced and the connection hinge 450 is not deformed even when a somewhat excessive external force is applied to the lid 3, and the lid 3 can be smoothly opened and closed. Is maintained.

  The connecting hinge 450 has an inclined shape that rises toward the end on both sides of the intermediate portion 457. For this reason, the rigidity of the connecting hinge 450 is increased, and the connecting hinge 450 becomes strong.

  Further, the reinforcing vein 459 is provided on both side portions 458 connecting the grip portions 451 and 452 and the support root portions 453 and 454, avoiding the intermediate portion 457. For this reason, the length of the reinforcing vein 459 can be made longer than that provided in the intermediate portion 457, and the reinforcement of the connecting hinge 450 can be increased.

  Furthermore, since the reinforcing vein 459 is provided so as to protrude inward of the connecting hinge 450 having a curved shape, it is suitable for bending with a press.

  Moreover, in said Example, the height (raised height) of a reinforcement vein is the same over the full length. The strength of the connecting hinge can be further increased by making the height of the reinforcing vein higher on the support base portion side and lower on the gripping portion side.
