Furthermore, the wiring cover cover 5 is a rectangular plate which is smaller than the front door 4 and has substantially the same size as the opening 3B on the rear side of the frame 3 and is rotatably attached to the hinges 10 and 10 It is possible to open and close the opening 3B on the rear side of the frame 3 by making it half open independently of the front door 4.

Here, the half-opened structure and the holding structure in the closed posture of the wiring cover cover 5 which is an essential part of the present invention will be described in detail.
First, the structure relating to the single opening of the front door 4, that is, the hinge 10, the hinge 10 includes the first pin receiving member 11, the second pin receiving member 12, and the hinge pin 50. The first pin receiving member 11 is formed in a cylindrical shape extending in the vertical direction (the hole located at the center functions as an axial hole), and is provided inside the bent portion of the right side of the front door 4. Further, the second pin receiving member 12 is folded back to the right from the tip of the plate-like fixing portion 14, a pair of upper and lower arm pieces 15 and 15 bent forward from the left end of the fixing portion 14, and And the pin receiving portions 17a and 17b provided at the tip of each of the folded pieces 16. The pin receiving portion 17a provided at the tip of the upper folded piece 16 has a base 18a circular in top view and a shaft 19a protruding upward from the upper surface of the base 18a. The shaft portion 19a has a cylindrical shape smaller in diameter than the base portion 18a, and is coaxially disposed with the base portion 18a, and a pin hole 20 is bored so as to penetrate from the tip end surface of the shaft portion 19a to the bottom surface of the base portion 18a. ing. On the other hand, the pin receiving portion 17b provided at the tip of the lower folded piece 16 has a base 18b circular in top view and a shaft 19b protruding downward from the lower surface of the base 18b. The base 18 b is coaxially disposed with the base 18 a, and the bottom of the base 18 a and the upper surface of the base 18 b are separated by the same vertical length of the first pin receiving member 11. The shaft 19b is cylindrical with a diameter smaller than that of the base 18b, and is coaxial with the base 18b, that is, coaxial with the base 18a and the shaft 19a. Pin holes 20 are drilled so as to penetrate over the upper surface.

  Then, when assembling the hinge 10 and attaching the front door 4 so as to be freely openable, the fixing portion 14 of the second pin receiving member 12 is screwed and fixed at a predetermined position on the front surface of the frame 3. Further, with respect to the second pin receiving members 12, 12 fixed to the frame 3, while inserting the bent portion on the right side of the front door 4 between the folded pieces 16, 16 and the fixing portions 14, 14, The pin receiving member 11 is positioned between the bases 18 a and 18 b of the second pin receiving members 12. Then, the hinge pin 50 is inserted from the shaft portion 19a side of each second pin receiving member 12 to the pin hole 20 on the base 18a side, the shaft hole of the first pin receiving member 11, and the pin hole 20 on the base 19b side. Just do it. Then, as shown in FIG. 6, the front door 4 is attached to the frame 3 via the hinges 10 and 10, and can be opened in half with the hinge pin 50 as an axis.

  Next, the wiring cover cover 5 is mounted in such a manner as to pivotally support the shaft portions 19a and 19b of the hinges 10 and 10, respectively. That is, at the right end of the wiring covering cover 5, pivot support portions 30, 30 for pivotally supporting the pivot portions 19a, 19b are provided vertically separated by a distance corresponding to the hinges 10, 10. Each pivot portion 30 has a pair of arm pieces 31 31 provided at predetermined intervals in the upper and lower direction, and a pivot support claw 32 provided at the tip of each arm piece 31. Each arm piece 31 is formed in an L-shape in top view that protrudes forward from the surface of the wiring cover 5 and is bent to the right (outside) on the tip side. In addition, each pivotally supporting claw 32 is formed by curving a strip-like metal plate in a C-shape in top view, and in a posture in which the open portion where the end portions are separated is directed to the right (outside) It is fixed to On the other hand, on the tip end side of the shaft portion 19a, a pair of chamfered portions 21a, 21a whose peripheral surfaces are chamfered in the vertical direction over a predetermined width are provided to face each other across the center of the shaft portion 19a. The width of the shaft portion 19a at the chamfered portions 21a and 21a is the same as the distance between the end portions of the open portion of the pivot support claw 32. Further, on the peripheral surface of the shaft 19b, the portions in the same phase as the chamfers 21a and 21a of the shaft 18a are all chamfered from the tip to the base (chamfers 21b and 21b are provided) The width of the shaft portion 19 b is also the same as the distance between the end portions of the open portion of the shaft support claw 32. A circumferential surface portion 23 which is not chamfered is left below the lower ends of the chamfered portions 21a, 21a in the shaft portion 19a.

  Then, when the wiring cover cover 5 is attached in an openable manner, the positions of the open portion of the upper shaft support claw 32 of each shaft support portion 30 and the chamfered portions 21a and 21a of the shaft portion 19a are aligned (FIG. 7) The shaft portion 19a is inserted into the shaft support claw 32. At this time, the lower pivoting claw 32 is also fitted with the axial portion 19b inside. Then, the wiring cover cover 5 may be moved downward in the above state, and the upper shaft support claw 32 may be placed on the base 18a exposed around the base end of the shaft portion 19a (that is, the shaft portion 19a The upper surface of the base 18a exposed around the proximal end of the lower end functions as a support step 22 for supporting the pivot 32 from below. Then, the wiring cover cover 5 is attached to the hinges 10, 10 with the shaft portions 19a, 19b fitted in the upper and lower pivot support claws 32, 32, respectively. It can be opened. In addition, since the circumferential surface portion 23 wider than the chamfered portions 21a and 21a is fitted in the pivot support claw 32 placed on the base portion 18a, the shaft portion 19a is dropped from the pivot support claw 32 It is not supposed to. When it is desired to remove the wiring covering cover 5, the wiring covering cover 5 is lifted until the locations of the chamfered portions 21a and 21a are located in the pivotal support pawl 32, and the opening of the pivotal support pawl 32 and the chamfered portion 21a. , And 21a, and the shaft 19a may be removed from the shaft support claw 32.

  However, it is conceivable that the wiring cover 5 may be inadvertently moved upward and the wiring cover 5 may come off the hinges 10. Then, the regulation member 40 as shown in FIG. 5 is attached. The restricting member 40 includes a main body 41 formed in a C-shape into which the shaft portion 19 b can be inserted similarly to the pivot support claw 32, and a knob 42 extending from the main body 41. Then, after the wiring cover cover 5 is attached to the hinges 10 and 10, the restriction member 40 is a main body between the lower pivoting claw 32 and the shaft portion 19b in each of the pivoting portions 30 as shown in FIG. You can insert 41. Then, the upward movement of the wiring cover cover 5 is restricted by the restriction member 40, and the careless removal of the wiring cover cover 5 is prevented.

Further, a structure relating to the holding of the wiring covering cover 5 in the closed posture will be described.
The upper and lower portions at the left end of the wiring cover 5 are provided with locking members 51 for holding the wiring cover in the closed position. Each locking member 51 includes a casing member 54 fixed to the rear surface of the wiring cover 5 and a claw member 53 attached to the casing member 54. The claw member 53 is a block body which is long in the left-right direction, and the left end portion thereof is formed in a tapered shape whose rear surface is an inclined surface. In addition, the claw member 53 is provided with a knob 52 projecting forward. And such a claw member 53 is attached to the casing member 54 in a state in which the knob 52 is protruded to the front of the wiring cover cover 5 through an operation window opened in the wiring cover cover 5. Further, the claw member 53 is slidable in the left-right direction with respect to the casing member 54, and a projecting position (locking position) in which the left end portion of the claw member 53 protrudes leftward from the casing member 54 It is biased to. On the other hand, the left end of the claw member 53 can be fitted into the left bent portion 8 of the frame 3 at the position corresponding to the locking members 51 when the wiring cover 5 is attached. 7, 7 are formed.

  Then, in order to hold the wiring covering cover 5 in the closing posture covering the opening 3B on the rear side of the frame 3, it is only necessary to set the wiring covering cover 5 in the opening posture to the closing posture. That is, when the left end portion of the claw member 53 abuts on the peripheral edge of the opening 3B of the frame 3 when the wiring cover 5 moves to the closed posture, the inclined surface of the claw member 53 is the peripheral edge of the opening 3B of the frame 3 The claw member 53 is pushed to the right from the projecting position in such a manner that the part moves relatively. Then, when the claw member 53 reaches the notch 7, the urging force of the urging member causes the claw member 53 to return to the projecting position, and the left end of the claw member 53 is fitted into the cutout 7, thereby covering the wiring cover 5 will be held in the closed position (FIG. 8). In order to open the wiring cover 5, the knob 52 may be extracted from the inside of the notch 7 by operating the knob 52 (it may be positioned at the release position).

  According to the storage box 1 having the above configuration, the frame 3 fixed to the front surface of the box body 2 along the opening of the box body 2 is interposed between the wiring cover cover 5 and the box body 2 I am doing it. Then, when the wiring cover cover 5 is in the closed position, the frame 3 is provided with the notches 7 and 7 which can be locked by the locking members 51 provided on the wiring cover cover 5. . Therefore, even if distortion occurs in the box body 2, the deformation of the frame 3 is suppressed to a small degree, so that the positional relationship between the locking members 51, 51 and the notches 7, 7 is difficult to shift. Can be held securely in the closed position.

  Further, the locking member 51 is provided with a casing member 54 fixed to the wiring covering cover 5 and a claw member 53 attached to the casing member 54, and the claw member 53 protrudes from the casing member 54 and is notched. The slide position between the projecting position to be fitted in 7 and the release position to be extracted from the notch 7 is slidable, so that the workability relating to the opening and closing of the wiring covering cover 5 is good.

  Furthermore, the hinge 10 is provided with shaft portions 19a and 19b extending in a direction parallel to the axial direction of the front door 4, while the wire support cover 5 supports the shaft support portion 30 for axially supporting the shaft portions 19a and 19b. The wiring cover cover 5 is mounted on the same side as the front door 4 so as to be able to open in a single-piece direction with the vertical direction as an axis by pivotally supporting the shaft portions 19a and 19b by the shaft support portion 30. That is, since the wiring cover cover 5 is attached to the frame 3 via the hinges 10, 10 instead of the box body 2, even if the box body 2 is distorted, the distortion is for the wiring cover It does not transmit to the cover 5. Therefore, the clearance between the frame 3 and the peripheral portion of the wiring cover cover 5 is kept uniform, and there is no hindrance to opening of the wiring cover cover 5, and the frame 3 can not be attached. Can not happen.

  Further, while the chamfers 21a and 21b whose peripheral surfaces are chamfered are provided in the shaft portions 19a and 19b, the same distance as the width of the shaft portions 19a and 19b at the location of the chamfers 21a and 21b in the shaft support 30 Since the pivot support claws 32 and 32 having a C-shaped top view having an open portion that is opened only is provided, the shaft support portion 30 axially supports the shaft portion 19a, that is, the hinge 10 of the wiring cover cover 5, The work relating to the attachment to 10 can be simplified.

  In addition, the structure which concerns on the storage box of this invention is not limited at all by the aspect as described in the said embodiment, The structure which concerns on the box main body, a front door, a hinge, a frame, and the cover for wiring coverings It can change suitably as needed in the range which does not deviate from the meaning of invention.

For example, in the above embodiment, the front door and the cover for the wire cover can be opened at one side about the right side, but it goes without saying that there is no problem if the left side can be opened at the other side. The positions, the number, etc. of the locking portions and the locked portions can be changed as appropriate depending on whether the one-side opening is possible.
In the above embodiment, the hinge is provided with the shaft so that the axis of the front door is coaxial with the axis of the wiring cover, but if the axis of the front door is parallel to the axis of the wiring cover It is also possible to configure so as not to be coaxial (for example, providing the shaft portion at the eccentric position of the base).
Furthermore, in the above embodiment, although the chamfered portion is provided in the shaft portion and the pivoting claw is provided in the shaft support portion, for example, after not providing the chamfered portion in the shaft portion, the shaft hole is provided at the tip of the arm It is also possible to adopt another configuration in which the shaft is supported by inserting the shaft into the shaft hole, or the shaft support is provided slidably in the vertical direction, and the shaft is supported by the shaft support. It is also possible to configure to slide the support.
In addition, although the front door and the cover for wiring cover are hinged to the frame in the above embodiment, they may be hinged to the box body as in the prior art instead of the frame.
