Description

The present invention relates to a retractable cabinet.

BACKGROUND ART In housing complexes such as condominiums, a lead-in board is installed at the lead-in position of a power line from the power grid in order to supply power to each unit. The lead-in board is equipped with a power meter and a circuit breaker at each branch of the power line that supplies power to each house. In many cases, power distribution equipment such as a power meter and a circuit breaker for a retractable panel are housed in a retractable panel cabinet and installed on the premises.

The intake panel cabinet is equipped with a box-shaped cabinet base that is open on the front side and in which a power meter, a circuit breaker, etc. are installed, and an opening/closing door that closes the opening of the cabinet base in an openable/closable manner. The opening/closing door is locked with the opening of the cabinet base closed, so that only specific people can access the inside.
In addition, the opening and closing doors have a confirmation window for visually checking the meter of the watt-hour meter at a position corresponding to each watt-hour meter in the cabinet base (a position in front of each watt-hour meter). Further, a light-transmitting plate member such as a glass plate is attached to each confirmation window of the opening and closing doors.

However, in the case of this retractable cabinet, a number of confirmation windows corresponding to each watt-hour meter must be formed on the opening/closing door, and a light-transmitting plate member must be individually attached to each confirmation window. For this reason, in this retractable cabinet, the structure of the opening/closing door is complicated, and the number of man-hours for assembling parts during manufacturing increases.

As a countermeasure to this problem, a retractable cabinet was devised in which a continuous large opening was formed in the area spanning multiple watt-hour meters on the opening/closing door, and a single light-transmitting plate member was attached to the opening. (For example, see Patent Document 1).

Patent No. 7100443

The conventional retractable cabinet mentioned above has a structure that allows multiple watt-hour meters to be viewed from the outside through a continuous opening, which simplifies the structure of the opening/closing door and reduces the number of man-hours required to assemble parts during manufacturing. be done.
However, in the conventional retractable cabinet described above, a continuous opening is formed in the opening and closing door so as to span the front of multiple watt-hour meters, so the electric wires placed around each watt-hour meter pass through the opening and are exposed to ultraviolet light. There are concerns that the wires will be exposed to sunlight and deteriorate due to ultraviolet rays. Furthermore, in the case of the above-mentioned conventional retractable panel cabinet, electric wires and other attached equipment arranged around each watt-hour meter are visible from the outside through the opening, and the appearance from the outside is likely to deteriorate.

Therefore, the present invention aims to simplify the structure of the opening/closing door and reduce the number of man-hours required for assembling parts, while also preventing deterioration of the electric wires placed around the watt-hour meter due to ultraviolet rays. It is an object of the present invention to provide a cabinet for a retractable panel that can suppress deterioration in appearance due to attachment equipment being visible from the outside.

The retractable cabinet according to the present invention employs the following configuration in order to solve the above problems.
That is, the retractable panel cabinet according to the present invention includes a cabinet base in which a plurality of watt-hour meters that display the integrated power of each unit of an apartment complex is housed, and an opening in an area spanning the front surface of the plurality of watt-hour meters. an opening/closing door that has a confirmation window and is attached to the front side of the cabinet base so as to be openable and closable; a light-transmitting plate member attached to the confirmation window; The electric power meter is characterized by comprising a light-shielding film attached to a region surrounding each of the watt-hour meters when viewed from the front.

With the above configuration, the front surfaces of the plurality of watt-hour meters housed inside the cabinet base can be visually recognized from the outside through the light-transmitting plate member attached to the confirmation window of the opening/closing door. Since the confirmation window is formed continuously so as to span the front surfaces of the plurality of watt-hour meters, there is no need to individually install a plurality of light-transmitting plate members corresponding to each watt-hour meter. Therefore, the structure of the opening/closing door can be simplified, and the number of man-hours for assembling parts to the opening/closing door can also be reduced.
In addition, since a light-shielding film is attached to the area surrounding each watt-hour meter when viewed from the front of the light-transmitting plate member, the wiring placed around each watt-hour meter is This makes it difficult for UV rays (sunlight) to hit directly. Furthermore, electric wires and other attached devices placed around each watt-hour meter are hidden by the light-shielding film, making it difficult to see the attached devices from the outside.

The light-shielding film may be partially or entirely removable from the light-transmitting plate member.

In this case, even if there is a change in the number of installed watt-hour meters or a change in the arrangement of the watt-hour meters in the cabinet base, the light-shielding film can be peeled off as appropriate, and a new light-shielding film can be attached to the light-transmitting plate member as necessary. Can be installed. Therefore, when this configuration is adopted, it is possible to flexibly respond to changes in the internal design of the cabinet base.

A plurality of stud bolts are provided protruding from a peripheral edge on the back side of the confirmation window of the opening/closing door to guide an outer peripheral end surface of the light-transmitting plate member that is overlapped with the peripheral edge of the confirmation window from the back direction, A supporting metal fitting that presses down the outer peripheral edge from the back side is stacked on the outer peripheral edge of the light-transmitting plate member, and the supporting metal fitting is attached to the light-transmitting plate member by a fixing nut tightened to each of the stud bolts. It may also be fixed to the opening/closing door.

In the retractable cabinet of this embodiment, when attaching a light-transmitting plate member to the confirmation window of the opening/closing door, the light-transmitting plate member is first inserted and placed inside the multiple stud bolts from the back side of the opening/closing door. do. At this time, the outer circumferential end surface of the light-transmitting plate member is guided by the stud bolt, so that the light-transmitting plate member is overlapped at a proper position on the outer circumferential edge portion on the back side of the confirmation window. Thereafter, the supporting metal fittings are stacked on the outer peripheral edge of the light-transmissive plate member from the back side, and fixing nuts are tightened onto each stud bolt, thereby fixing the supporting metal fittings together with the light-transparent plate member to the opening/closing door.
As a result, the light-transmitting plate member can be accurately and easily attached to the proper position on the back side of the confirmation window. Further, when the light-transmitting plate member is attached to the back side of the confirmation window in this manner, the outer peripheral edge of the light-transmitting plate member is reinforced with high rigidity by the support metal fittings. Since the light-transmissive plate member is attached to the periphery of the confirmation window, which has a large opening area and spans the front surfaces of the plurality of watt-hour meters, the overall rigidity and strength are likely to decrease. However, with this configuration, the outer peripheral edge on the back side of the light-transmissive plate member can be efficiently reinforced with the highly rigid support metal fittings, so the overall rigidity and strength of the light-transmissive plate member cannot be maintained sufficiently high. can.

A bent wall having approximately the same height as the thickness of the light-transmitting plate member may be provided at the outer peripheral edge of the support fitting.

In this case, when the support fitting is fixed to the door together with the light-transmitting plate member by tightening the fixing nut to the stud bolt, the bent wall of the support fitting will come into contact with the back surface of the door on the outside of the light-transmitting plate member. I will come into contact with you. As a result, it is possible to prevent the support fitting from being pressed against the light-transmitting plate member with excessive force by tightening the fixing nut, and it is also possible to prevent foreign matter from entering the peripheral edge of the light-transmitting plate member. This can be prevented by curved walls.

The retractable panel cabinet according to the present invention is provided with a confirmation window in the area extending over the front surface of the plurality of watt-hour meters of the opening/closing door, and a light-transmitting plate member is attached to the confirmation window, so that the structure of the opening/closing door is It is possible to simplify the process and reduce the number of man-hours required to assemble parts. Moreover, in the retractable cabinet according to the present invention, a light-shielding film is attached to a region of the light-transmissive plate member that is the area around each watt-hour meter when viewed from the front of the opening/closing door. Therefore, it is possible to prevent deterioration of electric wires arranged around the watt-hour meter due to ultraviolet rays, and to suppress deterioration in appearance due to attachments around the watt-hour meter being visible from the outside.
