Description

  The present invention relates to an information device used by being attached to a wall.

  Conventionally, for this type of information device, for example, an interphone system is constructed by connecting a door phone unit as a counterpart device installed outside the home using a signal line. There are devices that can communicate with each other (interphone master unit). An information device used as an interphone master unit includes an image display unit, and can display an image captured by the camera of the counterpart device by being connected to the counterpart device provided with the camera. There is also.

  Further, in recent years, the amount of protrusion of the body from the wall surface is suppressed, and a uniform appearance with the commonly used embedded wiring apparatus is produced, and the cost of the members used for mounting is reduced. For the purpose of illustration, an information device has been proposed in which a rear part of a body is embedded in a wall using an embedded box having a front opening, as in a well-known embedded wiring device (for example, Patent Documents). 1).

  By the way, in the information device described above, the internal circuit such as the power supply circuit and the information output means such as the video display unit are all arranged in one container, and therefore the function of the information device (for example, the screen size of the video display unit). Etc.), it is necessary to replace the entire information device. In particular, when the information device is attached in such a manner that the rear portion of the container is embedded in the wall, the replacement operation of the entire information device is troublesome.

  On the other hand, the main body module, which has a power supply circuit and an information port for transmitting and receiving information, is fixed to the wall in a manner that the rear portion of the container is housed in the wall using an embedded box, and the front surface of the main body module It is considered that the information device is divided into an exposed panel having information output means that is detachably attached to the side and receives power supply from the power supply circuit of the main body module, and the exposed panel can be replaced separately from the main body module. It has been. In this configuration, if the main body module is used in common, the function of the information device (for example, the screen size of the video display unit) can be easily changed by replacing the exposed panel.

In the information device divided into the main module and the exposed panel, the locking claw projecting on the back of the exposed panel is inserted into the locking hole opened on the front of the main module, and the tip of the locking claw is engaged. It is conceivable that the exposed panel is engaged with the main body module by being engaged with the opening periphery of the stop hole. Here, it is conceivable that a locking hole is provided in the exposed panel and a locking claw is provided in the body module. Space for housing is required, making it difficult to reduce the thickness of the exposed panel. To reduce the amount of protrusion from the wall surface by reducing the thickness of the exposed panel, a locking claw is provided on the exposed panel, and a locking hole is formed in the main module. It is desirable to provide

  By the way, generally, a plurality of types of embedding boxes having different dimensions in the left-right direction are used to attach the embedding type wiring apparatus. For example, N mounting frames (N is an integer) can be mounted in a single mounting frame (mounting frame that can be mounted by arranging three wiring devices with a single module size standardized for embedded wiring devices in the width direction) An embedded box is provided that is formed to the possible dimensions. Therefore, it is conceivable to provide a plurality of types of main body modules having different horizontal dimensions in accordance with the size of the embedding box.

  However, if the exposure panel that can be installed differs depending on the type of main module, it is necessary to prepare a separate exposure panel for each type of main module. As a result, a common exposure panel can be attached to multiple types of main modules. Compared to the case where possible, there is a problem that the cost for developing and manufacturing an exposed panel increases.

  In addition, when the main body module is mounted using an existing embedded box, the outer shape of the main body module body is limited by the shape of the embedded box. When it is configured to be inserted, there is also a problem that a space for storing components in the body of the main body module is narrowed.

  The present invention has been made in view of the above-mentioned reasons, and it is possible to attach a common exposed panel to a plurality of types of main body modules, and information that does not reduce the space in the body of the main body modules. An object is to provide an apparatus.

  According to the first aspect of the present invention, the main body module is provided with a power supply circuit and an information port for exchanging information, and is fixed to the wall in such a manner that the rear portion of the container is housed in the wall through a construction hole opened in a rectangular shape on the wall surface. And an exposed panel that is detachably attached to the front side of the main body module and includes at least one of information input means and information output means for receiving power supply from the power supply circuit. Each having a pair of mounting pieces extending in a direction away from each of the opposing sides and having a direction along the sides as a longitudinal direction, and the dimensions of the mounting pieces in the longitudinal direction are integral multiples of a predetermined unit dimension. It can be selected from a plurality of types of main body modules, and is embedded in the wall through a box hole formed in a portion of the mounting piece that overlaps the construction hole in the plane along the wall surface. The exposed panel is inserted into a pair of locking holes penetrating through the mounting piece of the main body module, and the tip is on the back side of the main body module. The box hole has a center position when the mounting piece is divided by the unit dimensions in the longitudinal direction. Each locking hole is formed in a portion which is on both sides of at least one box hole in the longitudinal direction of the mounting piece.

  According to this configuration, the box hole is formed at each central position when the mounting piece is divided by the unit dimension in the longitudinal direction, and each locking hole has at least one piece in the longitudinal direction of the mounting piece. Since it is formed on both sides of the box hole, the intervals between the pair of locking holes can be made uniform in a plurality of types of main body modules, and the pair of locking claws are engaged with the locking holes. It is possible to share the exposed panel attached together. Therefore, there is no need to prepare a dedicated exposed panel for each of the various main body modules, and there is an advantage that the cost for developing and manufacturing the exposed panel can be reduced. Further, since the locking hole is formed on the mounting piece extending from the opposite side of the front surface of the main body of the main body module, the tip of the locking claw inserted into the locking hole is the main module module. Therefore, the space in the body of the main body module is not narrowed while the locking hole is provided in the main body module. In addition, the box hole is formed in a portion of the mounting piece that overlaps the construction hole in the plane along the wall surface, and each locking hole is formed in a portion that is on both sides of the box hole in the longitudinal direction of the mounting piece. Therefore, although the tip of the locking claw inserted through the locking hole protrudes rearward from the back surface of the mounting piece, it protrudes into the construction hole and does not interfere with the wall.

  According to a second aspect of the present invention, in the first aspect of the invention, a module-side connector connected to a panel-side connector provided on the exposed panel is provided on the front surface of the body of the main body module, The positional relationship with the locking hole is common to the plurality of types of main body modules.

  According to this configuration, since the positional relationship between the module-side connector and the locking hole is common to a plurality of types of body modules, the electrical connection between the body module and the exposed panel can be achieved by connecting the module-side connector and the panel-side connector. Also in the case of connection, a common exposed panel can be used for a plurality of types of main body modules.

  According to the present invention, since the intervals between the pair of locking holes can be made uniform in a plurality of types of main body modules, a common exposed panel can be attached to the plurality of types of main body modules. In addition, since the locking holes are formed in the mounting pieces extending from the opposite sides of the front surface of the main body of the main module, the space in the main module body can be provided while the main holes are provided in the main module. There is an advantage that does not narrow.

  In the following embodiment, an interphone system is constructed by connecting to a door phone slave unit as a counterpart device installed outside the home by using a signal line, and the interphone system is connected to the counterpart device. The configuration of the information apparatus according to the present invention will be described using an interphone master unit that can communicate (call) between them as an example of the information apparatus.

The signal processing unit 42 includes an audio processing unit 44 that includes an amplifier that amplifies the audio signal, and a video transmission processing unit 45 that includes a demodulation circuit that demodulates the video signal and displays an image on the video display unit 15. In the present embodiment, the audio signal and the video signal are multiplexed and transmitted on the signal line. Therefore, the signal processing unit 42 is provided with a demultiplexing unit 42a that is inserted between the audio processing unit 44 and the video transmission processing unit 45 and the external interface unit 40 and separates the multiplexed audio signal and video signal. It has been.

  By the way, each of the main body module M and the exposed panel P is provided with attachment means for attaching the exposed panel P to the main body module M by engaging with each other.

  In the main body module M, as shown in FIG. 1A, a flange piece 23 protruding from the front surface of the lower mounting piece 10 and a locking hole 24 formed in a shape opening in a rectangular shape on the upper mounting piece 10. Are provided as attachment means. The flange 23 protrudes forward from the front surface of the mounting piece 10 and is formed in an L shape by extending the tip portion upward, and a plurality (two in this case) are arranged in parallel in the left-right direction. .

  The exposed panel P is formed at the lower end edge of the plate frame 13 and at a position corresponding to each flange piece 23, and is inserted between the tip of the flange piece 23 and the mounting piece 10 from above. The hooking piece 25 hooked on the piece 23 and the locking claw 26 protruding rearward from the position corresponding to each locking hole 24 on the back side of the panel body 12 as shown in FIG. Is provided. As shown in FIG. 4, a locking portion 27 that protrudes upward is provided at the distal end of the locking claw 26, and the locking portion 27 is closer to the proximal end of the locking claw 26. The upper surface is inclined so that the amount of protrusion from the surface increases.

  Thus, the exposed panel P is rotated so that the exposed panel P is rotated around the lower side of the front surface of the main body module M with the hook piece 23 as a fulcrum in a state in which the hook piece 25 of the exposed panel P is hooked on the hooked piece 23 of the main body module M. By pressing the upper end of P toward the main body module M, the locking pawl 26 of the exposed panel P is inserted into the locking hole 24 of the main body module M, and the locking portion 27 is locked into the locking hole on the back side of the mounting piece 10. The exposed panel P is attached to the main body module M by being engaged with the peripheral edge of the opening 24.

  According to this configuration, the locking hole 24 through which the locking claw 26 is inserted is formed in the attachment piece 10 extending from each end surface in the vertical direction of the body 3 in the main body module M. The tip of the locking claw 26 inserted through the locking hole 24 does not protrude into the body 3 of the main body module M. Therefore, by adopting a configuration in which the locking claw 26 is provided in the exposed panel P and the locking hole 24 is provided in the body module M, the space in the body 3 of the body module M is achieved while reducing the thickness of the exposed panel P. Will not narrow.

  Further, in the present embodiment, the locking holes 24 are respectively penetrated at portions on both sides in the left-right direction of one (right side) box hole 11 of the mounting piece 10. Here, since the hole 11 for boxes is formed in the site | part which overlaps with the construction hole H1 within the surface along a wall surface among the attachment pieces 10, the locking holes 24 arrange | positioned at the both right and left sides of the hole 11 for boxes are also included. 4, it will be located in the site | part which overlaps with the construction hole H1 within the surface along a wall surface. Therefore, although the front-end | tip part of the latching claw 26 penetrated by the latching hole 24 protrudes back from the back surface of the attachment piece 10, it will protrude in the construction hole H1 and will not interfere with a wall. That is, all the portions of the locking claw 26 that protrude rearward from the back surface of the mounting piece 10 are accommodated in the construction hole H1 and do not interfere with the wall material W.

  Further, the exposed panel P is connected to the locking claw 26 as shown in FIG. 4, and an engagement position for engaging the locking claw 26 with the locking hole 24 and a release position for releasing the engagement. An operation element 28 that is movable in the vertical direction along the front surface of the main body module M is provided. That is, when the operating element 28 is in the engaged position, the locking claw 26 is locked to the opening periphery of the locking hole 24 as shown in FIG. When the operation portion 28 is moved to the release position below the engagement position by operating the portion 28a, the engagement claw 26 moves downward from the position of FIG. Is released. The operation element 28 is accommodated in an accommodation space 29 provided inside the panel body 12 (here, behind the video display part 15) so that the operation part 28 a protrudes from the upper edge of the panel body 12. Here, an operation window 30 is opened at a portion of the plate frame 13 corresponding to the operation portion 28a so as to expose the operation portion 28a forward as shown in FIG. The part 28a is arranged in the operation window 30 and can be operated from the front side of the plate frame 13.

  The exposed panel P includes a coil spring 31 that biases the operating element 28 toward the engaging position. The operating element 28 is biased to the engaging position by the spring force of the coil spring 31 when not operated. Then, the operating portion 28a is pushed downward against the spring force of the coil spring 31 and moves to the release position.

  By the way, in the information apparatus A according to the present embodiment, the main body module M has a plurality of types of main body modules M in which the dimensions of the mounting piece 10 and the container 3 in the left-right direction (lateral direction) are integer multiples of a predetermined unit dimension. It is possible to select from. Here, the dimension in the left-right direction of the attachment piece 10 in the main body module M that can be attached to the single embedded box SB is defined as a unit dimension. That is, as described above, in addition to the double-unit body module M2 that can be attached to the double embedded box SB, as shown in FIG. 5, the single-unit body module that can be attached to the single embedded box SB. The main body module M to be used can be arbitrarily selected from the main body modules of the N continuous size that can be attached to the embedded box SB for M1 or N consecutive (N is 3, 4, 5,...).

  Here, the hole 11 for boxes is formed in each center position when the attachment piece 10 is divided by the said unit dimension in the longitudinal direction. Therefore, the number of box holes 11 formed in each attachment piece 10 varies depending on the type of the body module M. That is, for example, in a single embedded box SB, one set of a pair of upper and lower screw holes 20a is provided, and each mounting piece 10 of the main body module M1 corresponding to this is provided one at the center in the left-right direction. Whereas the box hole 11 is formed, the double embedded box SB has two pairs of upper and lower screw holes 20a in the left-right direction. Two pieces of box holes 11 are formed in the piece 10 in the left-right direction.

  Here, in the double-sized main body module M2, each box hole 11 has a center position when the mounting piece 10 is divided by the unit dimensions in the left-right direction, that is, the mounting piece 10 is 1: 3 in the left-right direction. Each of the position divided into 3 and the position divided into 3: 1 has a center. On the other hand, the size in the left-right direction of the single-unit body module M1 is ½ that of the double-unit body module M2. That is, there is not enough space between the box holes 11 in the double-sized main body module M2 to accommodate the single-sized main body module M1, and thus a pair of latches formed in the single-sized main body module M1. The locking holes 24 having the same spacing as the holes 24 cannot be formed at the center in the left-right direction of the double-sized main body module M.

  Therefore, in the present embodiment, as shown in FIGS. 1 and 5, in the N-unit body module M, locking holes 24 are formed on both sides of at least one (here, right) box hole 11. ing. According to this structure, although the center line of the left-right direction may shift | deviate with the exposed panel P and the main body module M, the space | interval of a pair of latching hole 24 can be equalized in multiple types of main body module M. The exposure panel P can be shared.

  Further, the positional relationship between the flanges 23 and the locking holes 24 as attachment means in the main body module M and the module side connector 4 (not shown in FIG. 5) is common to the plural types of main body modules M. . The exposed panel P includes a hook piece 25 and a locking claw 26 as mounting means, a panel-side connector 5, a flange piece 23 and a locking hole 24 as mounting means in the main body module M, and a module-side connector 4. It is arranged according to the position.

  With the above configuration, a common exposed panel P can be mounted on a plurality of types of main body modules M, and there is no need to prepare a separate exposed panel P for each of the various main body modules M. Therefore, development and manufacture of the exposed panel P are possible. There is an advantage that the cost for the cost can be reduced to a low cost.

  In the above embodiment, the example in which the present invention is applied to the information device A as an interphone master that can communicate with the counterpart device has been described. However, the present invention is not limited to this example. The present invention can be applied to various information devices such as a device that monitors and displays information such as the amount of power generation.
