Yes.
[0053]
As described above, the outer frame 12 of this embodiment is made of aluminum die-casting. In the molding, the frame main body 150 and the rectangular tube portion 240 are die-cut in the front-rear direction, and the bearing portion 210, the rib 212, and the support shaft are cut out. The hinge portion 16 and the flange portion 174 having 218 are formed by a slide die that is vertically cut.
[0054]
Next, the assembly / disassembly method of the hinge mechanism according to the present embodiment, the method of attaching and detaching the inner frame, and the operation will be described.
[0055]
In order to assemble the hinge mechanism having the above-described configuration, first, the through hole 224 is inserted into the support shaft 218 of the hinge portion 16 with the release lever 220 in the orientation shown in FIG. When the release lever 220 is arranged on the lower surface 16A of the hinge portion 16, the left side of the front surface of the lock portion 222 of the release lever 220 is substantially in contact with the rear surface 210B of the bearing portion 210 as shown in FIG. On the lower side, the lever portions 226 are hidden under the flange portions 174, respectively.
[0056]
Next, the U-shaped portion 234 is inserted into the through hole 242 of the rectangular tube portion 240 with the spring member 232 in the orientation shown in FIG. During the insertion of the U-shaped portion 234, the arc-shaped portion 238 of the spring member 232 hits the lower surface of the lock portion 222 of the release lever 220, and the front side of the spring member 232 is elastically deformed downward. When the convex portion 236 is inserted until it abuts against the front edge of the through hole 242 (the front surface of the rectangular tube portion 240), the arc-shaped portion 238 passes through the lock portion 222. Immediately after this passage, the front side of the spring member 232 is restored to its original state by the elastic force, and the arcuate portion 238 is accommodated in the concave portion 228 and engaged.
[0057]
Thus, in the spring member 232, the U-shaped portion 234 is inserted into the through hole 242 of the rectangular tube portion 240, the convex portion 236 abuts on the front surface of the rectangular tube portion 240, and the arc-shaped portion 238 is a concave portion. By being engaged with 228, it is prevented from coming off from the rectangular tube portion 240. Accordingly, the release lever 220 is supported by the rib 230 by the arc-shaped portion 238 engaged with the concave portion 228 and is sandwiched between the spring member 232 and the hinge portion 16 (see FIG. 9). As a result, the spring member 232 is attached to the outer frame 12 without coming out of the square tube portion 240, and the release lever 220 is attached to the lower surface 16A of the hinge portion 16 without coming off from the support shaft 218, thereby completing the assembly. .
[0058]
Furthermore, in this assembled state, as shown in FIG. 10A, one of the U-shaped portions 234 of the spring member 232 is separated from the inner surface of the through hole 242, and the U-shaped portion 234 is slightly elastic in the reduction direction. Deform. Since this elastic force acts on the concave portion 228 via the arc-shaped portion 238, the release lever 220 is biased in the clockwise direction in the bottom view around the support shaft 218 (in the direction of arrow C in FIG. 7), and the lock portion The front corner 244 of 222 is brought into contact with the rear surface 210A of the bearing 210, and the opening 216 of the groove 214 is closed by the lock 222 (closed position).
[0059]
Further, when the lever portion 226 is operated to be pulled forward against the biasing force of the spring member 232 (in the direction of arrow D in FIG. 10A), the release lever 220 rotates counterclockwise as viewed from the lower side around the support shaft 218. While rotating in the direction, the opening 216 of the groove 214 closed by the lock portion 222 is opened (open position). Along with this, the U-shaped portion 234 of the spring member 232 is further elastically deformed in the reduction direction, and when the above operation is stopped, the release lever 220 is urged by the urging force of the spring member 232 (elastic force of the U-shaped portion 234). It is rotated and returned to its original position.
[0060]
Further, when removing the release lever 220 and the spring member 232, the release lever 220 and the spring member 232 are removed from the spring member 232 in the reverse order of the attachment. First, an exposed portion of the spring member 232, for example, the convex portion 236 or the like is picked with a finger and pulled downward against the elastic force to separate the arc-shaped portion 238 from the concave portion 228. And the U-shaped part 234 is extracted and removed from the through-hole 242 of the square tube part 240 as it is. When the spring member 232 is removed, the release lever 220 is not supported and can be easily removed by being pulled out from the support shaft 218.

The upper side of the inner frame 14 can be moved relatively easily.
[0062]
Then, as shown in FIGS. 5A and 10A, the hinge pin 162 is moved closer to the hinge portion 16 from the right side (inner side) and moved to the left side (outer side) along the rear surface 210A of the bearing portion 210. Then, the hinge pin 162 contacts the curved surface 226A of the release lever 220. Further, when the hinge pin 162 is moved to the left side, the hinge pin 162 presses the curved surface 226A while slidingly contacting the curved surface 226A. As a result, the release lever 220 rotates counterclockwise when viewed from the bottom, and opens the opening 216 of the groove 214 as shown in FIG. Further, when the hinge pin 162 is moved to the left side, the hinge pin 162 passes through the curved surface 226A and enters the groove 214 as shown in FIG. Then, the release lever 220 is rotated in the clockwise direction in the bottom view by the urging force of the spring member 232, and the opening 216 of the groove 214 is closed by the lock portion 222 as shown in FIG. As a result, the hinge pin 162 cannot be detached from the groove 214 and is held in this state, and is supported rotatably on the bearing portion 210 of the hinge portion 16. By the above procedure, the inner frame 14 is attached to the outer frame 12 so that it can be opened and closed.
[0063]
On the other hand, when the inner frame 14 is removed from the outer frame 12, the release lever is normally biased rearward (in the direction of arrow R in FIG. 5A) by the spring member 232 and hidden under the flange 174. The lever portion 226 of 220 is hooked on the fingertip and operated so as to be pulled forward (in the direction of arrow F in FIG. 5A) against the biasing force of the spring member 232. Then, the opening 216 of the groove 214 that has been blocked by the lock portion 222 is opened, and the holding state of the hinge pin 162 is released. In this state, when the upper portion of the inner frame 14 is moved to the right side, the hinge pin 162 comes out of the groove portion 214 and is detached from the bearing portion 210 of the hinge portion 16. Then, the inner frame 14 can be removed from the outer frame 12 by lifting the inner frame 14 and detaching the lower hinge plate 180 from the hinge pin 200.
