DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a front view, a side view, and a bottom view showing an embodiment of the present invention. In the figure, reference numeral 1 denotes a cabinet body, which is molded from a synthetic resin in a box shape, and includes a circuit board and electronic components therein, and the back surface is fixed to a wall surface of a building. Reference numeral 2 denotes a cabinet door formed of synthetic resin in a box shape, which is provided with an operation panel 3, a handset body 4, a handset cover 5, a button 6 and a display panel 7 on the front surface, and a circuit board and electronic components are provided inside. It is provided so that it can be opened and closed by a hinge 9 facing the cabinet body 1. A coin key 8 locks the cabinet body 1 and the cabinet door 2. Reference numeral 10 denotes a curl cord.
The handset body 4 and the handset cover 5 are collectively referred to as a handset or a handset.
[0012]
A cabinet door 2 is attached to the cabinet body 1 so as to be opened by a hinge 9. The attachment position of the hinge 9 has a step difference from the opening position.
Here, the opening portion position refers to a surface that contacts the opening side of the cabinet body 1 and the opening side of the cabinet door 2, and the opening side of the cabinet body 1 in order to provide a step in the mounting position of the hinge 9. A step portion 9a is formed on the hinge mounting side, and a notch portion 9b corresponding to the step portion 9a is formed on the hinge mounting side on the opening side of the cabinet door 2.
And the attachment position of the hinge 9 is comprised so that it may approach the front side from the opening part position.
[0013]
In the control room control panel configured as described above, even when a plurality of units are arranged side by side and brought into contact with each other as shown in FIG. 2, the cabinet door 2 does not hit the adjacent cabinet body 1 at 90 degrees. It can be opened over the above, making it easy to perform internal inspection work. In addition, when using the control room control panel as a call control device, a video control device that controls the image of the housing information panel and the collective entrance is adjacent to the call control device, Since it is general, it is preferable that the left and right open / close angles can be made large in this way.
[0014]
When there is no step at the mounting position of the hinge 9, as shown in FIG. 3 showing the comparative example, a state where all the cabinet doors 2 cannot be unfolded occurs. This can be avoided by installing at intervals, but a large space is required.
In addition, by increasing the step 9a of the cabinet body 1 and the notch 9b of the cabinet door 2, it becomes possible to increase the opening / closing angle of the door, but the height of the notch 9b as shown in the figure, By making it about half the height of the door 2, there is no problem in strength.
[0015]
As shown in FIGS. 4 to 6, the coin key 8 provided on the cabinet door 2 has a tongue-like shape of the coin key 8 on a housing lock portion 1a erected in a U-shaped frame shape from the inner surface of the bottom of the cabinet body 1. The pieces 8a are crossed and locked.
In the horizontal piece 1c of the U-shaped housing lock part 1a, an inclined part 1b that is inclined upward from one side of the vertical piece 1d is provided. The length of the inclined portion 1b is about one third of the length of the horizontal piece 1c, and its height is substantially the same as the height of the tongue-like piece 8a.
The tongue-like piece 8a is attached to an axis that is orthogonal to the front surface of the cabinet door 2 and is provided at a position on the lateral side of the housing lock portion 1a. The coil spring K is fixed to the shaft so as to be pressed toward the front surface of the cabinet door 2.
[0016]
When the tongue-like piece 8a is located in the housing lock portion 1a due to the influence of the coil spring K, it is pressed inside the U-shaped frame-like horizontal piece 1c.
The flat part which contacts the tongue-like piece 8a of the housing | casing lock part 1a is set on the same plane as the tongue-like piece 8a.
Note that an L-shaped angle A is provided on the side of the tongue-shaped piece 8a so as to protrude from the back surface side of the door 2, and the tongue-shaped piece 8a is restricted so that it can rotate only 90 °.
[0017]
In the coin key 8 configured as described above, in this embodiment, the tongue-like piece 8a is rotated in a clockwise arrow direction. When the tongue-like piece 8a is rotated in the direction of the arrow, it slides along the inclined portion 1b of the housing lock portion 1a when turning into the inside of the housing lock portion 1a, so that it can be rotated without requiring a pressing operation. When the tongue-shaped piece 8a is rotated 90 ° from a position parallel to the U-shaped frame (unlocked state), the inclined portion 1b disappears, and the tongue-shaped piece 8a and the U-shaped frame are orthogonal to each other. It will be in the state and it will be pressed by the flat part (horizontal piece 1c), and locking will be completed. When unlocking from this state, it may be rotated 90 ° counterclockwise.
[0018]
However, in this case, since the tongue-like piece 8a cannot get over the inclined portion 1b simply by turning it, the tongue-like piece 8a is rotated while pushing the operation portion of the coin key above the inclined portion height so as to resist the coil spring. Let As a result, the tongue-like piece 8a is separated from the flat portion, gets over the inclined portion 1b, is detached from the housing lock portion 1a, and is unlocked. Therefore, locking can be performed by simply rotating, but the unlocking operation cannot be unlocked unless rotated while pressing.
[0019]
The operation panel 3 is provided so as to be separable from the cabinet door 2 and is fixed from the back side of the door 2 to the front surface of the cabinet door 2 in which an opening is formed in a frame shape. In addition, as shown in FIG. 7, the periphery of the operation panel 3 is configured such that the flange portion 3a provided so as to have a step from the surface is fitted into the opening of the door, but the step is formed as necessary. It is. As shown in FIGS. 7 and 8, the fixing portion 3b formed at a desired interval around the operation panel 3 is formed to have a stepped portion in a U-shape formed at a desired interval, and has a small hole. is there. Moreover, the fixing | fixed part 3c is set as the structure which pierced the ellipse in the collar part 3a.
[0020]
When the operation panel 3 configured as described above is fixed to the resin cabinet door 2, the peripheral shape of the opening formed in the frame shape of the cabinet door 2 as shown in FIG. A convex part that fits into the stepped part of the fixed part 3b is provided and screwed using a tapping screw or the like.
[0021]
In the type where the operation panel 3 is separated and independent and is installed on the metal plate 2a or metal door provided on the wall of the management room of an apartment house, high-rise building, or other large-scale buildings. A screw with a reamer screw or an M screw is inserted into the portion 3c and fixed to the metal plate 2a. Therefore, regardless of whether the door side is made of metal or resin, the operation panel can be easily mounted, and can be used for other installation types such as the wall-mounted type and the embedded installation type. .
In FIG. 8b, the screw may be inserted from the metal plate 2a side. In this case, a nut is provided on the operation panel 3c side to fix the screw.
