It is formed so as to be substantially concentric with the surface.
[0012]
Next, a method for assembling the main body 1 and the lid 2 will be described below with reference to FIGS.
First, as shown in FIG. 2, the hinge shaft 20 and the hinge receiver 10 are arranged to face each other, the lid portion 2 is positioned approximately 90 degrees with respect to the opening surface 19, and the hinge shaft 20 is moved in the direction of the arrow A. Move and place in the receiving part 11. FIG. 3 is a perspective view showing this state. At this time, one end of the screw hole 24 provided in the shaft portion 22 is located on the lower end 16 side of the main body portion 1.
Next, with the shaft portion 22 as the center of rotation, the lid portion 2 is rotated approximately 90 degrees in the direction of arrow B, the opening surface 19 is covered with the lid portion 2, and the main body portion 1 and the lid portion 2 are closed. To do. FIG. 4 is a perspective view showing the vicinity of the hinge receiver 10 and the hinge shaft 20 in this state.
[0013]
As shown in FIG. 4, by rotating the lid portion 2, the convex portion 18 of the main body portion 1 and the convex portion 18 of the lid portion 2 overlap, and the insertion hole 17 and the insertion hole 27 are aligned. . At this time, the shaft portion 22 rotates approximately 90 degrees, so that the screw hole 24 is positioned at the position of the long hole 14 on the extending portion 12 side of the receiving portion 11.
Then, a screw 25 is screwed into the screw hole 24 through the long hole 14. FIG. 5 is a perspective view showing this state. At this time, the lower surface of the head 25 b of the screw 25 does not necessarily have to contact the seat portion 15.
In this state, the screw 25 contacts the end portion 14a of the long hole 14, and in the open state, the screw 25 contacts the end portion 14b. FIG. 6 is a cross-sectional view showing a contact state between the screw 25 and the end portion 14b in the open state. As can be seen in this drawing, the screw 25 abuts against the end portion 14b, whereby the main body portion 1 and the lid portion 2 can be held at a predetermined angle. In this embodiment, the lid portion 2 is held at an angle of about 90 degrees with respect to the main body portion 1. As a result, the main body 1 and the lid 2 are rotated within a range where the ends 14 a and 14 b of the long hole 14 and the screw 25 are in contact with each other. When in this rotation range, the shaft portion 22 and the inner wall surface of the receiving portion 11 abut against the force in the direction of separating them, so that the shaft portion 22 falls off the receiving portion 11 by the force in that direction. There is nothing.
Further, after the screw 25 is screwed, the bolt 4 is inserted into the insertion holes 17 and 27 through the washer 3, and the bolt 4 and the nut (not shown) are screwed together, whereby the main body 1 and the lid 2 are connected. To fix. FIG. 7 is a schematic diagram showing this state.
[0014]
By adopting the above configuration, in the state where each bolt 4 is loosened, the screw 25 is screwed into the screw hole 24 of the shaft portion 22 disposed in the receiving portion 11 via the long hole 14. It is possible to prevent the lid 2 from falling off. Further, since the long hole 14 is provided along the rotation direction, it is possible to rotate the shaft portion 22 around the lid portion 2 in a state where the lid portion 2 is locked to the main body portion 1, and the screw 25 is long. The lid 2 can be held at a position in contact with the end 14 b of the hole 14.
Further, since the opening / closing mechanism of the main body 1 and the lid 2 can be constituted by only the hinge shaft 20, the hinge receiver 10 and the screw 25, the structure can be simplified, the number of parts can be reduced, and the cost and weight can be reduced.
Further, since the main body 1 and the lid 2 can be rotatably assembled simply by mounting the hinge shaft 20 to the hinge receiver 10 and screwing the screw 25 into the screw hole 24, the work efficiency of the assembly Is significantly improved.
[0015]
In the above embodiment, the screw hole 24 penetrates the shaft portion 22, but the screw hole 24 does not have to penetrate the shaft portion 22.
In the above embodiment, the main body 1 is provided with the hinge receiver 10 and the lid 2 is provided with the hinge shaft 20 correspondingly. However, the main body 1 is provided with the hinge shaft, and the lid 2 is hinged. A receptacle may be provided. Moreover, in the said Example, although the main-body part 1 and the cover part 2 provided only one kind among the hinge members which make a pair, respectively, you may provide both types of hinge members in each.
In the above embodiment, the screw 25 is used as the locking means, and the screw 25 is screwed into the screw hole 24. However, the lid 2 can be prevented from falling off, and the hinge shaft 20 is attached to the hinge receiver 10. Other members may be used as long as they can be rotatably supported. For example, it is good also as a structure which provides a hole part in the axial part 22, and attaches a latching means to this hole part by fitting. In particular, as in this embodiment, when the main body 1 and the lid 2 are within the rotation range, the shaft 22 and the inner wall surface of the receiving portion 11 come into contact with the force in the direction of separating the two. Since the hinge shaft 20 and the hinge receiver 10 are in the locked state, the locking means need not have a head. In this case, if the protruding amount of the locking means from the outer surface of the hinge receiver 10 is larger than the movable amount of the shaft portion 22 in the receiving portion 11, the hinge receiver 10 and the hinge shaft 20 are sufficiently locked. Yes.
[0016]
Moreover, in the said Example, when the main-body part 1 and the cover part 2 are in the rotation range, with respect to the force of the direction which separates both, the axial part 22 and the inner wall face of the receiving part 11 contact | abut. Although the opening part of the receiving part 11 was formed in the direction opposite to the opening surface 19, this opening part may be formed in arbitrary directions. For example, by forming the opening of the receiving portion 11 in the direction of the lower end 16 of the main body 1, it is possible to widen the rotation range of the main body 1 and the lid 2. Further, when the opening portion of the receiving portion 11 is formed in the same direction as the opening surface 19 of the main body portion 1 and the shaft portion 22 is in the range of rotation when the main body portion 1 and the lid portion are within the rotation range, the force in the direction to separate them from each other However, the shaft portion 22 and the inner wall surface of the receiving portion 11 may not be in contact with each other. However, in this case, it is necessary to prevent the hinge shaft 20 from coming off by providing the locking means with a head and locking the head to the hinge receiver 10.
Moreover, in the said Example, although it was set as the structure by which the cover part 2 is hold | maintained at about 90 degree | times with respect to the main-body part 1 in the open state, this angle may be arbitrary. The angle formed between the lid 2 and the main body 1 in the open state can be adjusted by changing the end 14b of the long hole 14.
In the above embodiment, the screw 25 is in contact with the end portion 14a in the closed state, but the screw 25 may not be in contact with the end portion 14a in the closed state.
Moreover, in the said Example, although it was set as the structure by which the hinge receiver 10 was continuously provided in the convex part 18, the hinge receiver 10 may be provided in arbitrary positions.
Moreover, in the said Example, although it provided so that the direction from the arm part 21 in the hinge axis | shaft 20 to the front-end | tip part of the axial part 22 might become opposite, this direction may be the same direction or the direction which opposes.
