Can be pivotally supported.
[0034]
In order to manufacture the upper front frame hinge 17, the hinge main body 23, the bearing body 24, the lock body 25, the guide plate 26, the support body 28, and the abutting plate 50 are formed by pressing (punching, bending, etc.) a sheet metal. Form. Therefore, the hinge body 23, the bearing body 24, the lock body 25, the guide plate 26, the support body 28, and the contact plate 50 can be easily manufactured by pressing without performing complicated processing such as die casting. The thickness of the sheet metal is preferably 0.5 to 10 mm, more preferably 1 to 8 mm, and most preferably 2 to 5 mm. If the thickness is less than 2 mm, the upper front frame hinge 17 may not be sufficiently durable. On the other hand, if it exceeds 5 mm, press working may be difficult.
[0035]
Next, to assemble the upper front frame hinge 17, first, the guide plate 26 and the contact plate 50 are fixed to the pedestal portion 32. Next, the bearing body 24 and the lock body 25 are disposed on the upper surface of the pedestal portion 32, and the compression coil spring 29 is fitted into the first spring mounting hole 35 and the second spring mounting hole 36. Subsequently, the support body 28 is disposed on the upper surface of the bearing body 24 and the lock body 25, and the rivet 27 is disposed between the first rivet insertion hole 37, the first rivet insertion recess 38, and the second rivet insertion recess 39. The two rivet insertion holes 40 are inserted in this order and crimped to the pedestal 32.
[0036]
Subsequently, in order to attach the upper front frame hinge 17 to the front frame 15, the lower surface of the pedestal plate 30 is brought into contact with the upper surface of the upper left corner portion of the front frame 15, and the front surface of the fixed plate 31 is placed at the upper left corner of the front frame 15. The fixing plate 31 is affixed to the front frame 15 with screws or the like.
[0037]
Next, in order to attach the front frame 15 to the outer frame 14, as shown in FIG. 2, first, the front frame 15 is arranged so that the front surface of the front frame 15 is substantially orthogonal to the front surface of the outer frame 14. Next, the lower support shaft insertion hole 56 is inserted into the lower support shaft 53 while the upper portion of the front frame 15 is inclined forward, and the lower bearing portion 55 is overlapped with the lower shaft attachment portion 52. Subsequently, the sliding surfaces 45 and 46 are brought into contact with the tip of the upper support shaft 22, and the upper part of the front frame 15 is pressed toward the outer frame 14. At this time, as shown in FIGS. 3A and 3B, the sliding surfaces 45 and 46 are slid by the upper support shaft 22. The bearing body 24 moves horizontally in front of the front frame 15 against the urging force of the compression coil spring 29, and the lock body 25 moves horizontally in the rear of the front frame 15. At this time, the bearing body 24 is guided to the inner surface of the lock body 25, and the lock body 25 is guided to the inner surface of the guide plate 26 and the inner surface of the bearing body 24. At the same time, the inner surface of the first elongated hole 43 is pressed in the moving direction of the bearing body 24 by the first pin 41, and the inner surface of the second elongated hole 44 is pressed in the moving direction of the lock body 25 by the second pin 42. Is done. Then, the inner surfaces of the long holes 43 and 44 are slid by the pins 41 and 42, and the support 28 is rotated clockwise with the rivet 27 as an axis when viewed from above.
[0038]
With the horizontal movement of the lock body 25 and the support body 28, the left side of the first shaft support recess 33 is opened as shown in FIG. 3B, and the upper support shaft 22 extends from the opening portion to the first shaft support recess 33. Get in. Then, as shown in FIG. 3C, the pressing of the sliding surfaces 45, 46 by the upper support shaft 22 is released, and the bearing body 24 moves horizontally behind the front frame 15 by the urging force of the compression coil spring 29. To do. At the same time, the inner surface of the first long hole 43 is pressed in the moving direction of the bearing body 24 by the first pin 41. Then, the inner surface of the first elongated hole 43 is slid by the first pin 41, and the support 28 is rotated counterclockwise as viewed from above with the rivet 27 as an axis. As the support body 28 rotates, the inner surface of the second elongated hole 44 slides on the second pin 42, and the lock body 25 moves horizontally in front of the front frame 15. At this time, the opening portion of the first shaft support recess 33 is closed by the second shaft support recess 34, and the upper support shaft 22 is sandwiched between the first shaft support recess 33 and the second shaft support recess 34. Further, the biasing force of the compression coil spring 29 maintains the second shaft support recess 34 in a state where the opening portion of the first shaft support recess 33 is closed.
[0039]
Subsequently, in order to remove the front frame 15 from the outer frame 14, the front frame 15 is first opened so that the front frame 15 is substantially orthogonal to the outer frame 14 as shown in FIG. 4. Next, the upper part of the front frame 15 is pressed to the right, and the inner side surface of the first shaft support recess 33 is pressed to the upper support shaft 22. Then, the inner surface of the first shaft support recess 33 receives a reaction force from the upper support shaft 22, and the bearing body 24 resists the biasing force of the compression coil spring 29 as shown in FIG. Move horizontally forward. At the same time, the inner surface of the first long hole 43 is pressed in the moving direction of the bearing body 24 by the first pin 41. Then, while the inner surface of the first long hole 43 is slid by the first pin 41, the support 28 is rotated in the clockwise direction when viewed from above with the rivet 27 as an axis. As the support body 28 rotates, the inner surface of the second elongated hole 44 slides on the second pin 42, and the lock body 25 moves horizontally behind the front frame 15. As the bearing body 24 and the lock body 25 move horizontally, the left side of the first shaft support recess 33 is opened.
[0040]
At this time, the longitudinal directions of the first long hole 43 and the second long hole 44 are provided so as to be orthogonal to the direction in which the bearing body 24 and the lock body 25 linearly move. Therefore, when the first pin 41 linearly moves with the horizontal movement of the bearing body 24, the first pin 41 can slide in the longitudinal direction of the first long hole 43. In addition, when the second long hole 44 rotates with the rotation of the support 28, the second pin 42 can slide in the longitudinal direction of the second long hole 44. Therefore, the linear motion of the bearing body 24 can be smoothly transmitted to the linear motion of the lock body 25 through the rotation of the support body 28.
[0041]
In this open state, the upper part of the front frame 15 is inclined forward of the outer frame 14, and the upper support shaft 22 is removed from the first support recess 33. Subsequently, the lower support shaft insertion hole 56 is removed from the lower support shaft 53 by lifting the front frame 15.
[0042]

Further, a support body 28 is pivotally supported on the hinge body 23 by a rivet 27 so that the linear motion of the bearing body 24 and the lock body 25 is interlocked by the support body 28. Further, the bearing body 24 is biased by the compression coil spring 29, and the first shaft support recess 33 and the second shaft support recess 34 sandwich the upper support shaft 22 by the biasing force of the compression coil spring 29. In this case, the sliding surfaces 45 and 46 are brought into contact with the upper support shaft 22 and the upper portion of the front frame 15 is pressed toward the outer frame 14 by pressing the upper portion of the front frame 15 toward the upper support shaft 22. Can be attached. Further, in a state where the upper support shaft 22 is supported by the first support recess 33 and the second support recess 34, the upper front frame hinge 17 is pushed from the upper support shaft 22 by pressing the bearing body 24 against the upper support shaft 22. Can be removed. Therefore, the upper front frame hinge 17 can be attached and detached without manually operating an operation member such as a lever piece, and the front frame 15 can be easily attached and detached from the outer frame 14.
