In addition, in order to adjust the number of springs of the elastic member to an appropriate value, a slit-like groove 122a having an appropriate width dimension is formed in the bent part 122 as necessary.
[0045]
As shown in FIG. 18A, the elastic member 120 has a distal end side that covers the guide hole 113 and is disposed inside the bent portion 122. At this time, the upper surface of the flat portion 123 is located below the upper surface of the introduction portion 114, and the oblique side portion 124 is located behind the standing portion that connects the introduction portion 114 and the protruding portion 112, and the support shaft portion 125 at the front end. Is disposed between the upper and lower surfaces of the protrusion 112. In other words, the free end side of the elastic member 120 is disposed so as to be protected at a position where it cannot be directly viewed from the right side (introduction direction of the support shaft 135), and this collides with the side surface of the elastic member 120 when the support shaft 135 is introduced. For example, this member is configured not to be deformed or damaged.
[0046]
On the other hand, the upper swing metal fitting 130 hinged to the upper fixing metal fitting 110 is fixed to the back side of the front frame 2, the swing side base 131 is bent at a right angle from the swing side base 131, and horizontally forward. It consists of a swinging plate-like portion 132 that protrudes and a support shaft 135 that is fixed to the front end portion of the swinging plate-like portion 132 and protrudes downward. After that, the front frame 2 is fixed to the left upper surface of the front frame 2 by using fastening means such as screws.
[0047]
It should be noted that the distance between the upper surface of the fixed-side plate-like portion 22 in the lower fixing bracket 20 and the upper surface of the protruding portion 112 in the upper fixing bracket 110 (the interval between the upper and lower support surfaces), and the attachment attached to the lower surface side of the lower swing bracket 30. The distance between the lower surface of the auxiliary member 40 and the lower surface of the swing side plate-like portion 132 in the upper swing metal fitting 130 (the distance between the upper and lower supported surfaces) is set to be substantially the same. 110 and 20 are configured to swingably support the swing metal fittings 130 and 30, respectively, and to support the entire front frame 2 so as to be freely opened and closed.
[0048]
On the other hand, the protruding height of the support shaft 135 in the upper swing metal fitting 130 is set somewhat larger than the step between the upper surface of the protruding portion 112 and the upper surface of the introducing portion 114. In other words, the lower end surface of the support shaft 135 is set to be lower than the upper surface of the introduction portion 114 when the lower swing metal fitting 30 is supported on the lower fixing metal fitting 20. Thus, when the support shaft 135 is positioned in the guide hole 113 from the introduction portion 114, the support shaft 135 is held in the guide hole 113, and this does not come off to the introduction portion 114 side.
[0049]
Further, the length of the shaft portion 23 of the lower fixing bracket 20 is set longer than the length of the support shaft 135 of the upper swing bracket 130. Accordingly, when the support shaft 135 is positioned in the guide hole 113 from the introduction portion 114, the lower swing metal fitting 30 is difficult to come off from the shaft portion 23 of the lower fixing metal 20. Can be easily hinged.
[0050]
In the present embodiment, a guide member 128 that guides the support shaft 135 to the guide hole 113 may be provided in the introduction portion 114 as indicated by a two-dot chain line in FIG. In this way, when the support shaft 135 is engaged with the guide hole 113, the support shaft 135 is guided by the guide member 128 and guided into the guide hole 113, so that the connecting operation of the front frame 2 can be performed more easily and easily. It can be done lightly. Further, the left end of the guide member 128 is extended to protect the right edge of the bent portion 122, or the support shaft 135 is configured to cover the bent portion 122 and the fixed piece 121. The hinge device can be prevented from coming into contact with the elastic member 120 and more durable.
[0051]
Further, in this embodiment, as shown by a two-dot chain line in FIG. 17, the upper side portion 111a of the fixed side base portion 111 is protruded forward to form the flange portion 118, and the front frame 2 is closed with the front frame 2 closed. The portion 118 may be positioned so as to protrude above the upper swing metal fitting 130. If it does in this way, when the front frame 2 is lifted in the closed state, the flange portion 118 can restrict the upward movement of the upper swinging metal member 130 and maintain the hinge connection of the upper and lower hinge devices. Thereby, it is possible to effectively prevent an illegal act of releasing the hinge connection in a state where the front frame 2 is closed, and to provide a fair game.
[0052]
The hinge connection of the upper hinge mechanism 100 and the lower hinge mechanism 10 configured as described above will be described. In order to attach the front frame 2 to the outer frame 1 in a swingable (laterally open) open / close and detachable manner by the upper hinge mechanism 100 and the lower hinge mechanism 10 from the state in which the outer frame 1 and the front frame 2 are separated, In the hinge mechanism 10, the lower fixing bracket 20 and the lower swing bracket 30 configured in the lower hinge mechanism 10 are hinge-connected.
[0053]
In order to make the lower fixing bracket 20 and the lower swing bracket 30 hinge-connected, first, the lower swing bracket 30 is positioned to the right of the shaft portion 23 of the lower fix bracket 20 to accommodate the shaft in the lower swing bracket 30. The direction of the hole 33 is directed to the shaft portion 23 (the front frame 2 is directed substantially perpendicular to the outer frame 1). Then, the lower swing metal fitting 30 is moved leftward toward the shaft portion 23, and the shaft hole 33 a and the shaft portion 23 are connected to the guide hole 33 b by passing the shaft portion 23 through the guide hole 33 b of the lower swing metal fitting 30. Engage.
[0054]
At this time, when the shaft portion 23 is introduced into the guide hole 33b, the shaft portion 23 comes into contact with the guide portion 42 of the engagement assisting member 40, and the shaft portion 23 relatively moves rearward along the guide hole 33b as shown in FIG. When this is done, the guide portion 42 is pressed by the shaft portion 23 and elastically deforms so that the engagement assisting member 40 is pushed to the left and right. As shown in FIGS. 9, 10, and 13, when the shaft portion 23 is positioned in the shaft hole 33 a, the engagement assisting member 40 is restored and the shaft engaging portion 41 of the engagement assisting member 40 is replaced with the shaft portion 23. And the relative movement of the shaft portion 23 to the guide hole 33b in the lower swing metal fitting 30, that is, the movement of the lower swing metal fitting 30 in the direction of releasing the hinge connection with the lower fixing metal fitting 20 is restricted.
[0055]
In this manner, the shaft portion 23 of the lower fixing metal fitting 20 is engaged with the shaft hole 33a of the upper swing metal fitting 30 and the shaft engagement portion 41 of the engagement assisting member 40, and the side portion of the shaft portion 23 is held. In this state, the lower fixing bracket 20 and the lower swing bracket 30 are easily hinged, and the front frame 2 can swing with respect to the outer frame 1 with the shaft portion 23 serving as a swing shaft. Therefore, the front frame 2 can be easily attached to the outer frame 1, and once attached, the front frame 2 is firmly held without being detached from the outer frame 1 regardless of the swinging position. Can do. The front frame 2 is supported by the lower fixing bracket 20 of the lower hinge mechanism 10. Further, the swing axis of the front frame 2 relative to the outer frame 1 in the lower hinge mechanism 10 is the same as the swing axis of the front frame 2 relative to the outer frame 1 in the upper hinge mechanism 100.
[0056]
Next, in the upper hinge mechanism 100, the upper fixing bracket 110 and the upper swing bracket 130 configured in the upper hinge mechanism 100 are hinge-connected. In order to make the upper fixing bracket 110 and the upper swing bracket 130 hinge-connected, first, the front frame 2 supported by the lower hinge mechanism 10 is tilted so that the upper swing bracket 130 is moved from the right side of the upper fixing bracket 110. The support shaft 135 is moved in the direction of the introduction portion 114.
[0057]
At this time, the height of the lower end surface of the support shaft 135 is set to be slightly lower than the upper surface of the introduction portion 114 in a state where the lower swing metal fitting 30 is supported on the lower fixing metal fitting 20. The shaft 135 is guided by a chamfered portion 114 s formed at the side edge of the introduction portion 114 and enters the introduction portion 114. As a result, the upper end side of the front frame 2 that is supported in one piece by the lower hinge mechanism 10 is supported by the upper fixing bracket 110, and the wobbling (free tilting) of the front frame 2 is suppressed.
[0058]
Next, the front frame 2 is tilted in the upright direction so that the support shaft 135 passes through the introduction portion 114 and enters the guide hole 113, and the support shaft 135 is positioned in the guide hole 113. At this time, since the left edge of the guide hole 113 is formed higher than the upper surface of the introduction portion 114, when the front frame 2 tries to tilt to the left beyond the upright position (for example, the front frame 2 vigorously left Even when the support shaft 135 is tilted in the direction, the outer peripheral surface of the support shaft 135 comes into contact with the left edge of the guide hole 113 to restrict the movement, and the support shaft 135 is held in the guide hole 113. When the support shaft 135 enters the guide hole 113 in this way, the support shaft 135 that is guided by the chamfered portion 114 s and rides on the introduction portion 114 moves down in the guide hole 113 and is locked and held in the guide hole 113. Thus, the state cannot return through the introduction part 114 (see FIG. 18A).
[0059]
Subsequently, the front frame 2 is tilted so that the support shaft 135 moves along the guide hole 113 toward the front end of the protruding portion 112. At this time, since the guide hole 113 is formed in a taper shape having a width in the plan view that is wide on the base side and narrows from the intermediate portion toward the tip side, the support shaft 135 is guided to the left and right edges of the guide hole 113. So as to move toward the shaft support hole 115. Further, in this movement process, the lower end portion of the support shaft 135 contacts and presses the oblique side portion 124 of the elastic member 120, and moves forward while elastically deforming the elastic member 120 downward (see FIG. 18B). .
[0060]
When the support shaft 135 moves forward until it is positioned in the shaft support hole 115, the contact between the lower end portion of the support shaft 135 and the upper surface of the elastic member 120 is released, and the elastic member 120 is engaged by elastic force. Return to the previous shape. As a result, the support shaft 135 is sandwiched between the shaft support hole 115 formed at the front end portion of the guide hole 113 and the support shaft portion 125 formed at the distal end portion of the elastic member 120, and the support shaft 135 is rotatably held. (See FIG. 17 and FIG. 18 (c)).
[0061]
As a result, the support shaft 135 of the upper swing metal fitting 130 is positioned in the shaft support hole 115 of the upper fixing metal fitting 110 and engages with the support shaft portion 125 of the elastic member 120, and the shaft support hole 115 and the support shaft portion 125 are engaged with each other. With the side portion of the support shaft 135 held, the upper fixing bracket 110 and the upper swing bracket 130 are hinge-connected, and the front frame 2 can swing with respect to the outer frame 1 with the support shaft 135 as a swing shaft. become. As described above, the swing axis of the front frame 2 relative to the outer frame 1 in the upper hinge mechanism 100 is the same as the swing axis of the front frame 2 relative to the outer frame 1 in the lower hinge mechanism 10.
[0062]
With the upper hinge mechanism 100 and the lower hinge mechanism 10 connected in this manner, the front frame 2 can swing (open sideways) to the outer frame 1 while the weight of the front frame 2 is supported substantially evenly. Installed. As can be seen from the above, in the upper hinge mechanism 100, the direction in which the upper swing metal fitting 130 is hinged to the upper fixing metal 110 is the front-rear direction, and in the lower hinge mechanism 10, the lower swing metal fitting 30 is connected to the lower fixing metal 20. The direction in which the hinges are connected is the left-right direction, and the connection directions of the upper hinge mechanism 100 and the lower hinge mechanism 10 are different from each other, so that the front frame 2 is forcibly pulled in one direction and the upper hinge mechanism 100 and the lower hinge mechanism 10 The hinge connection is released, and the front frame 2 can be prevented from being inadvertently removed from the outer frame 1.
[0063]
In order to remove the front frame 2 from the outer frame 1, first, the upper fixing bracket 110 and the upper swing bracket 130 are separated in the upper hinge mechanism 100, and then the lower fixing bracket 20 and the lower portion in the lower hinge mechanism 10. The swing metal fitting 30 may be separated. In order to separate the upper fixing bracket 110 and the upper swing bracket 130 from each other, the front frame 2 is lifted up and swinged while the front frame 2 is opened at a predetermined angle with respect to the outer frame 1. That's fine. In order to separate the lower fixing bracket 20 and the lower swing bracket 30 from each other, the front frame 2 may be lifted upward as in the case of the upper fixing bracket 110 and the upper swing bracket 130.
[0064]

Thus, the relative movement of the shaft portion 23 to the guide hole 33b, that is, the movement of the lower swing metal fitting 30 in the direction of releasing the hinge connection with the lower fixing metal fitting 20 is restricted. The frame 2 can be easily mounted, and once mounted, the front frame 2 can be firmly held without being detached from the outer frame 1 regardless of the swinging position.
[0065]
Further, in the upper hinge mechanism 100, the support shaft 135 of the upper swing metal fitting 130 is made to enter the guide hole 113 from the side from the introduction portion 114 of the upper fixing metal fitting 110, and then the support shaft 135 is moved forward. With the simple operation, the support shaft 135 is positioned in the shaft support hole 115 of the upper fixing bracket 110 and is held rotatably and without detachment. Therefore, the front frame 2 can be easily attached to the outer frame 1. In addition, once mounted, the front frame 2 can be firmly held without being detached from the outer frame 1 regardless of the swinging position.
[0066]
Further, since the connection directions of the upper hinge mechanism 100 and the lower hinge mechanism 10 are different from each other, the front frame 2 is forcibly pulled in one direction, and the hinge connection between the upper hinge mechanism 100 and the lower hinge mechanism 10 is released. Can be prevented from being inadvertently removed from the outer frame 1.
