Description

Technical Field

[0001] The present invention relates to a storage box for electrical equipment and a cabinet for storing electrical equipment.

Background Art

[0002] Electrical equipment such as switchboards and control panels are provided with a drawing holder for storing circuit diagrams, operation manuals, etc. in a cabinet for storing electrical equipment that constitutes the electrical equipment. For example, Patent Document 1 discloses a structure in which an auxiliary storage housing is provided with respect to a housing main body, and drawings and the like can be taken out from the inside of the auxiliary storage housing by performing a rotation operation.

Patent Document 1

[0004] By the way, the technique described in Patent Document 1 is convenient because storage items can be taken out from both the inside and the outside of the cabinet for storing electrical equipment, but the work during assembly is troublesome. One reason for this is that part of the tightening and fixing work required for forming the auxiliary storage housing must be performed with the opening / closing part open. Also, the work of attaching the auxiliary storage housing to the main body of the cabinet for storing electrical equipment was troublesome. In addition, in order to remove dust and foreign matter that have entered the inside of the auxiliary storage housing, the assembled auxiliary storage housing may need to be disassembled, but this disassembly work was time-consuming. As a means of solving such problems, it is conceivable to adopt a structure in which the housing main body and the opening / closing part are assembled without using a fixing member. However, if the housing main body and the opening / closing part are simply assembled without using a fixing member, when taking out drawings and the like from the inside of the auxiliary storage housing, the opening / closing part may accidentally come off together and there is a risk of dropping.

Summary of the Invention

Problems to be Solved by the Invention

[0005] The inventor of the present invention has made earnest studies on this point and tried to solve it. The problem to be solved by the present invention relates to a storage box having a main body member and a movable member, and makes it possible to easily attach and detach a movable member capable of storing stored items, while suppressing the movable member from falling off the main body member when taking out the stored items from the movable member.

Means for Solving the Problem

[0006] In order to solve the above problems, there is provided a storage box for electrical equipment capable of partitioning a space for protecting stored items, which includes a main body member having a shaft portion and a movable member rotatably supported by the shaft portion of the main body member. The movable member is provided with a storage portion that can be accommodated in the storage box, a groove portion having a sliding contact portion at an end that slidably contacts the shaft portion, and an inclination maintaining portion that can contact the main body member so as to maintain the inclination of the movable member at an opening angle at which storage work can be performed on the storage portion. When the movable member is removed from the main body member, it is structured to move from a state where the shaft portion is located in the groove portion to a state where the shaft portion is located outside the groove portion. When the movable member is at the opening angle maintained by the inclination maintaining portion, it is a storage box for electrical equipment that can regulate the movable member from moving so as to be removed from the main body member.

[0007] Further, it is possible to regulate the movable member from moving so as to be removed from the main body member by engaging a main body engaging portion provided on the main body member and a movable engaging portion provided on the movable member. It is preferable to adopt a configuration in which the main body engaging portion and the movable member can be adjacent to each other by rotating the movable member around the shaft portion so that the inclination maintaining portion contacts the main body member.

[0008] Further, it is preferable to adopt a configuration in which the movable engaging portion contacts the main body member in a state where the main body member and the inclination maintaining portion are in contact with each other and the inclination of the movable member is maintained at an opening angle at which storage work can be performed on the storage portion.

[0009] Further, it is preferable that both side surfaces of the movable member are provided with the groove portions, and the storage portion is provided with a storage guide portion on the inner side of both side surfaces of the movable member.

[0010] Further, it is preferable that the electric equipment storage cabinet includes the storage box.

Effect of the Invention

[0011] In the present invention, regarding a storage box including a main body member and a movable member, it is possible to easily attach and detach a movable member capable of storing stored items, and to suppress the movable member from falling off the main body member when taking out the stored items from the movable member.

Embodiments for Carrying Out the Invention

[0013] Embodiments for carrying out the invention are shown below. As can be understood from FIGS. 1 to 6, the storage box 1 for electric equipment of the present embodiment can partition a space for protecting stored items with a main body member 10 having a shaft portion 11 and a movable member 30 rotatably supported on the shaft portion 11 of the main body member 10. Further, the movable member 30 is provided with a storage portion 31 that can be accommodated in the storage box 1, a groove portion 32 having a sliding contact portion 32a that slidably contacts the shaft portion 11 at an end portion, and an inclination maintaining portion that can contact the main body member 10 so as to maintain the inclination of the movable member 30 at an opening angle at which storage work can be performed on the storage portion 31. Furthermore, when the movable member 30 is removed from the main body member 10, it is a structure that moves the shaft portion 11 from a state where it is located in the groove portion 32 to a state where it is located outside the groove portion 32, and when the movable member 30 is at an opening angle maintained by the inclination maintaining portion, it is possible to regulate the movement of the movable member 30 so as to be removed from the main body member 10. For this reason, regarding the storage box 1 including the main body member 10 and the movable member 30, it is possible to easily attach and detach the movable member 30 capable of storing stored items, and to suppress the movable member 30 from falling off from the main body member 10 when taking out the stored items from the movable member 30.

[0014] Hereinafter, a storage box 1 capable of storing drawings such as a circuit diagram of a switchboard will be described as an example. In addition to the drawings, the storage box 1 in this example can also store operation manuals (for example, operation manuals for devices installed inside the switchboard and devices installed on the outer surface), measuring instruments or tools used for inspection work, and the like.

[0015] As can be understood from FIGS. 1 to 4, the storage box 1 of the embodiment includes a main body member 10 having a shaft portion 11 and a movable member 30 rotatably supported by the shaft portion 11. The movable member 30 is provided with a storage portion 31 capable of storing drawings and the like. By rotating the movable member 30, it is possible to switch between a state where objects can be put in and taken out of the storage portion 31 and a state where they cannot. When the state is such that objects cannot be put in and taken out of the storage portion 31, a space for protecting the stored objects is partitioned by the main body member 10 and the movable member 30, and the storage portion 31 is accommodated in the storage box 1. In order to easily maintain this state, connecting members 51 are provided on each of the movable member 30 and the main body member 10.

[0016] Since it is preferable that the connecting member 51 can release the connected state when a slightly strong force is applied, in the embodiment, a member that can maintain the connected state by using elastic force or magnetic force, such as a spring catch or a magnet catch, is used. Since the storage box 1 is provided with the connecting member 51, when the connecting members 51 are connected to each other when the movable member 30 is closed, it is possible to suppress the movable member 30 from rotating and opening due to the weight or impact of the stored objects. In the example shown in FIG. 1, a finger hook portion 33 on which a finger can be hooked is provided at the upper end of the movable member 30 so that a slightly strong force can be easily applied to the movable member 30.

[0017] Also, if a packing 12 is interposed between the main body member 10 and the movable member 30 when the movable member 30 is closed, it is possible to prevent water and dust from entering through the gap between the main body member 10 and the movable member 30, and the waterproof and dustproof effect can be enhanced. The packing 12 is preferably disposed at a portion located above the storage portion 31 when the storage box 1 is closed, and may be attached to either the main body member 10 or the movable member 30, but is preferably attached to the main body member 10 that does not hinder the putting in and taking out of the stored items in the storage portion 31. In the example shown in FIG. 2, the packing 12 is provided beside the connecting member 51.

[0018] Incidentally, the main body member 10 shown in FIGS. 1 to 3 is configured to form a substantially rectangular parallelepiped-shaped space inside, and includes a main body back plate 21, main body side plates 22 extending from the right end and the left end of the main body back plate 21, a main body top plate 23 provided to connect the main body back plate 21 and both main body side plates 22 on the upper side of the main body member 10, and a main body bottom plate 24 provided to connect the main body back plate 21 and both main body side plates 22 on the lower side of the main body member 10.

[0019] Shaft portions 11 are provided on the main body side plates 22 located on the left and right of the main body member 10 shown in FIG. 3. Further, a main body engaging portion is provided by bending a portion continuous with the main body bottom plate 24 to form a bent portion 25. The main body engaging portion is a portion that can engage with a movable engaging portion provided on the movable member 30. By forming the main body engaging portion by bending a part of the member forming the outer contour of the main body member 10 in this way, even when forming the main body engaging portion, there is no need for an operation such as welding and fixing a separate member, so the workability during manufacturing can be improved. In the example shown in FIG. 3, the bent portion 25 serving as the main body engaging portion is provided to continue from both the left and right ends of the main body bottom plate 24, and each has a portion protruding forward from the main body bottom plate 24 at a position higher than the main body bottom plate 24.

[0020] Next, the movable member 30 will be described. The movable member 30 shown in Fig. 4 is a member having a substantially L-shaped portion in side view that forms a front plate portion 41 and a bottom plate portion 42, and a substantially U-shaped member in plan view that forms a back plate portion 43 and side plate portions 44 located on the right and left sides of the back plate portion 43, which are welded and formed (see Figs. 4 and 5). The space partitioned by these two members in the storage box 1 is a storage portion 31 capable of storing a circuit diagram.

[0021] Further, the side plate portion 44 provided on the movable member 30 is provided with a sliding contact portion 32a that engages with the shaft portion 11 provided on the main body member 10. In the example shown in Fig. 4, the upper end of the groove portion 32 extending upward from the lower end of the side plate portion 44 is the sliding contact portion 32a. In this example, the groove portion 32 is linear, but the groove portion 32 may be in a form that continues from the end of the plate-like portion to the sliding contact portion 32a, and is not necessarily limited to a linear shape. For example, a curved groove portion 32 or a zigzag-shaped groove portion 32 may also be used. In the example shown in Fig. 4, since the sliding contact portion 32a contacts the upper portion of the shaft portion 11, it is difficult for foreign objects or the like to be caught between the sliding contact portion 32a and the shaft portion 11.

[0022] Also, in the movable member 30 of the example shown in Fig. 4, a bottom plate portion 42 is formed so as to extend from the front plate portion 41 to the vicinity of the back plate portion 43. Further, in the example shown in Fig. 4, a movable engagement portion capable of engaging with the main body engagement portion is provided at a position adjacent to the bottom plate portion 42. Specifically, the movable engagement portion is provided by forming flat plate portions 45 extending from the left and right ends on the front side of the bottom plate portion 42.

[0023] Incidentally, the movable member 30 of the embodiment can be detached from the main body member 10 by simply moving it appropriately. When attaching the movable member 30 to the main body member 10, the shaft portion 11 of the main body member 10 is fitted into the groove portion 32 formed in the side plate portion 44 of the movable member 30, and the movable member 30 is moved downward from above, so that the sliding contact portion 32a located on the closed end side of the groove portion 32 and the shaft portion 11 come into contact, and the movable member 30 is set on the main body member 10. In this state, the movable member 30 can rotate about the shaft portion 11 of the main body member 10 (see Figs. 6 to 8).

[0024] When removing the movable member 30 from the main body member 10, by moving the movable member 30 upward with a predetermined inclination, the shaft portion 11 is disengaged from the groove portion 32, and the movable member 30 is also removed from the main body member 10. Note that this predetermined inclination is the inclination of the angle between the completely closed state (see FIG. 6) and the completely open state (see FIG. 8), and the inclination in the state as shown in FIG. 7 can be exemplified.

[0025] In the example shown in FIG. 4, the length of the bottom plate portion 42 of the movable member 30 in the left - right direction is formed to be equal to or less than the length between the bent portions 25 provided at both left and right ends of the main body bottom plate 24. Therefore, when attaching the movable member 30 to the main body member 10, the bottom plate portion 42 of the movable member 30 can be attached without contacting the bent portion 25.

[0026] In the examples shown in FIG. 3 and FIG. 6, in the state where the storage box 1 is closed, the shaft portion 11 of the main body member 10 is configured to be located in front of the center of gravity of the movable member 30. Therefore, when the movable member 30 is slightly open, the self - weight of the movable member 30 acts so that the storage box 1 closes. Also, since the sliding contact portion 32a of the groove portion 32 is arranged near the front plate portion 41 of the movable member 30, even if the stored item is relatively heavy, the movable member 30 is suppressed from moving in the opening direction. With such a configuration, it becomes easier to maintain the state where the storage box 1 is closed even in a state where the connecting members 51 are not connected or in a case where the connecting members 51 are not provided.

[0027] Further, the movable member 30 is configured such that the center of gravity can be located in front of the shaft portion 11 in a state where the movable member 30 is slightly tilted. For this reason, until the angle of rotating the movable member 30 forward (that is, in the opening direction) reaches a predetermined angle, the self - weight of the movable member 30 acts so that the storage box 1 closes, and when rotated beyond that angle, the self - weight of the movable member 30 acts so that the storage box 1 opens. Therefore, since the angle by which the operator needs to tilt the movable member 30 when opening the storage box 1 is about the above - mentioned predetermined angle, the burden on the operator can be suppressed.

[0028] In the example shown in FIG. 1, when the movable member 30 is rotated by a certain amount in the opening direction of the storage box 1, the lower end at the rear of the movable member 30 abuts against the main body back plate 21 of the main body member 10, and the opened angle can be maintained (see FIG. 9). That is, in the example shown in FIG. 9, the lower end at the rear of the movable member 30 serves as the inclination maintaining portion. When the main body member 10 and the inclination maintaining portion come into contact, the storage box 1 is maintained in an opened state at a predetermined angle, so that the circuit diagram and the like stored in the storage portion 31 can be easily taken out.

[0029] In the examples shown in FIGS. 4 and 9, resin contact members 34 are provided on the left and right of the lower end at the rear of the movable member 30. This contact member 34 serves as the inclination maintaining portion and abuts against the main body back plate 21 of the main body member 10 when the movable member 30 is rotated. In this example, since the resin contact member 34 is used, the impact when the movable member 30 abuts against the main body member 10 can be absorbed. Also, scratches, dents, and deformations due to the contact between the movable member 30 and the main body member 10 can be suppressed.

[0030] Also, in the examples shown in FIGS. 8 and 9, when the movable member 30 is rotated and the main body member 10 and the inclination maintaining portion are in contact, and the opened angle of the movable member 30 is maintained, the main body engaging portion and the movable member are adjacent to each other. More specifically, the flat plate portion 45 that functions as the movable engaging portion is located below the bent portion 25 that functions as the main body engaging portion. Even if an attempt is made to move the movable member 30 upward to remove it from the main body member 10 while maintaining this angle, the flat plate portion 45 will abut against the bent portion 25, so that the separation of the movable member 30 from the main body member 10 is restricted. Therefore, when taking out the stored items placed in the storage portion 31, it is possible to prevent the movable member 30 from coming off and falling.

[0031] Note that when the main body member 10 and the inclination maintaining portion are in contact and the opened angle of the movable member 30 is maintained, the flat plate portion 45 and the bent portion 25 do not necessarily have to be in contact. For example, when the movable member 30 is moved to be removed while maintaining the angle, if the flat plate portion 45 and the bent portion 25 come into contact and restrict the movement of the movable member 30, that is sufficient.

[0032] However, in a state where the main body member 10 and the inclination maintaining portion are in contact with each other and the inclination of the movable member 30 is maintained at an opening angle at which the storage operation into the storage portion 31 is possible, if the flat plate portion 45 functioning as the movable engaging portion comes into contact with the main body member 10, a contact portion can be provided in addition to the inclination maintaining portion in contact with the main body back plate 21. Therefore, the force applied from the movable member 30 to the main body member 10 can be dispersed, and the deformation of the inclination maintaining portion in contact with the main body back plate 21 can be suppressed. Note that, instead of providing the inclination maintaining portion in contact with the main body back plate 21, the flat plate portion 45 functioning as the movable engaging portion may also function as the inclination maintaining portion.

[0033] Incidentally, the storage portion 31 in the example shown in FIG. 4 is provided with a storage guide portion 46 located inward of both side surfaces of the movable member 30. In the example shown in FIG. 4, the both side plate portions 44 of the movable member 30 are provided with groove portions 32, but the storage guide portion 46 extending in the vertical direction is located inward of the both side plate portions 44 provided with the groove portions 32. For this reason, it is possible to guide the stored items such as circuit diagrams to be stored near the center of the storage portion 31, and it is possible to prevent the stored items from coming into contact with the shaft portions 11, the sliding contact portions 32a, the main body engaging portions, and the movable engaging portions arranged at both left and right ends of the storage box 1 (see FIG. 10). Therefore, it is possible to prevent the stored items from being pinched by them during rotation.

[0034] Note that the storage guide portion 46 in the example shown in FIG. 4 is provided only at the upper portion of the storage portion 31, but it may be formed to continue to the bottom plate portion 42 of the movable member 30. With such a structure, even when storing not only drawings such as circuit diagrams with a certain height but also small tools, it is possible to prevent them from coming into contact with the shaft portions 11 and the like.

[0035] Further, the storage box 1 does not necessarily have to be limited to the configuration described above. For example, the main body back plate 21 of the main body member 10 may be provided with an engaging protrusion 27 functioning as the main body engaging portion. In the example shown in FIG. 11, the engaging protrusion 27 formed of a separate member is welded and fixed to the main body member 10, but it does not necessarily have to be limited to such a configuration.

[0036] In the example shown in FIG. 11, an engagement groove 48 that functions as a movable engagement portion is provided in a back plate portion 43 of a movable member 30. The engagement protrusion 27 is disposed on an orbit along which the engagement groove 48 moves when the rotating member rotates so that the storage box 1 opens (see FIG. 12). Therefore, by rotating the movable member 30, the engagement protrusion 27 can be fitted into the engagement groove 48. In a state where the engagement protrusion 27 is fitted into the engagement groove 48, the engagement protrusion 27 does not necessarily abut so as to restrict the movement of the movable member 30 so as to be removed from the main body member 10. For example, when the movable member 30 is moved so as to be removed while maintaining the inclination, the lower end of the engagement groove 48 may be configured to abut against the engagement protrusion 27.

[0037] Note that the engagement protrusion 27 may be provided on the movable member 30 and the engagement groove 48 may be provided on the main body member 10. Further, the engagement protrusion 27 or the engagement groove 48 does not need to be provided on the back side of the storage box 1 and may be provided on the side surface of the storage box 1.

[0038] Incidentally, the storage box 1 of the embodiment can be attached to an electric equipment storage cabinet 8 that constitutes a distribution board (see FIGS. 13 and 14). In order to enable such a thing, mounting holes 13 are provided in a main body back plate 21 of the main body member 10. Therefore, for example, it is possible to tighten and fix the door or side surface of the electric equipment storage cabinet 8 using bolts and nuts.

[0039] Note that the storage box 1 of the embodiment does not necessarily need to be attached to the electric equipment storage cabinet 8. For example, if the storage box 1 is attached to a wall surface or a mounting base so as to be provided together with the electric equipment storage cabinet 8, a circuit diagram or the like can be taken out and used immediately. Of course, also in this case, electric equipment and communication equipment can be stored and used in the storage box 1.

[0040] As described above, the present invention has been described by taking the embodiment as an example, but the present invention is not limited to the above embodiment and can be variously modified.
