Description

  The present invention relates to a remote control device that remotely controls electrical equipment mainly used for home automation (HA).

  With the spread of HA in recent years, a system has been put into practical use that enables remote control of home appliances such as air conditioning units (air conditioners), lighting fixtures, etc. from the outside using communication terminals such as mobile phones. Yes.

  In addition, a conventional remote control system employed in an HA or the like has a control unit called a telecontroller connected to a communication terminal through a communication line installed in a home, and the control unit and an electric device controlled by the control unit Are connected by wire, and the operation of the electric device is controlled by a control signal sent from the control means to the electric device. For example, in the case of an air conditioner, a control signal is transmitted and received by connecting to a dedicated control terminal. In the case of a lighting fixture, the power source is turned on and off by a relay or the like.

  However, recently, many lighting fixtures are also controlled by an infrared remote control, and air conditioners can also be controlled by an infrared remote control, so it is not controlled by connecting to a dedicated control terminal or a relay for power ON / OFF by wire, It is required to control from a tele controller using an infrared remote controller. That is, a remote control device that controls an electric device by being fixed to a wall surface of a room and connected to a telecontroller is required instead of a remote control device that a person holds and operates. However, since the infrared signal transmitted from the remote control device has directivity, if the mounting position of the remote control device is poor with respect to the electrical device installed in advance, the electrical device will respond to the signal transmitted from the remote control device. There is a problem that it does not operate normally or does not operate at all, and is limited by the installation location of the remote control device.

  In order to solve such a problem, the present invention greatly relaxes the restriction on the mounting position of the remote control device by providing an angle adjusting means capable of adjusting the irradiation direction of the signal transmitted from the remote control device mounted on the wall surface or the like. It was devised as the first purpose to do.

However, as the angle adjusting means as described above, for example, a mechanism capable of rotating the pan direction of the video camera by 360 ° by a universal joint mechanism such as a “dome type video camera device” described in Patent Document 1 is used. Can be considered.
JP 2000-244781 A.

  However, the universal joint mechanism described in Patent Document 1 has a structure in which the rotation direction of the video camera can be rotated 360 ° by combining many parts formed of metal. Since it is complicated and difficult to downsize, when it is used in a remote control device that controls electrical equipment used for HA, etc., the remote control device becomes large, and thus requires a lot of space for installation. There is a problem that the remote control device becomes expensive.

  Accordingly, a second object of the present invention is to provide a remote control device that can adjust the signal transmission direction with a simple configuration in order to improve the point that the remote control device is large and expensive. It is what.

  Next, the operation of the thus configured remote control device will be described.

  The electrical equipment 3 whose operation is controlled by the remote control device main body 2 is installed in each room in the home, and in controlling the operation of these electrical equipment 3, the room of each electrical equipment 3 is installed. The remote control device body 2 is attached to a wall surface or the like.

  When the remote control device main body 2 is attached, the installation position is not limited as long as the infrared rays emitted from the light emitting element 12b of the signal transmission unit 12 are not blocked.

  When the mounting position of the remote control device main body 2 is determined, the cable 7 for connecting the control means 1 and the remote control device main body 2 is first wired from the mounting position, and the mounting bracket 15 is fixed to the position.

  Further, the remote control device main body 2 inserts the tubular portion 10i of the angle adjusting means 10 from the attachment hole 5d of the middle case 5, and fits the tubular portion 10i to the semicircular portion of the attachment hole 5d.

  In this state, the angle adjustment means 10 adjusts the irradiation direction of the signal transmission unit 12.

  The light emitting element 12b of the signal transmission unit 12 attached to the movable part 10a of the angle adjusting means 10 has the best reception sensitivity when the optical axis is aligned with the light receiving window (not shown) of the electrical device 3. Since the irradiation angle of the light emitting element 12b is wide and the plurality of light emitting elements 12b are attached to the movable portion 10a, it is sufficient to direct the infrared irradiation direction of the light emitting element 12b toward the electric device 3.

  In adjusting the irradiation direction, first, the movable portion 10a is rotated around the pin 10g of the angle adjusting means 10 as shown in FIGS. 11 and 12, and the movable portion 10a is inclined in this state. As shown in FIG. 3, the movable portion 10a is rotated in the left-right direction with the cylindrical portion 10i as an axis so that the front surface of the movable portion 10 faces toward the electric device 3.

  When the front surface of the movable part 10a is directed toward the electric equipment 3, the movable part 10a is finely moved again around the pin 10g to finely adjust the angle. At this time, the support part protruding from the back surface of the movable part 10a Since the angle holding member 11 elastically pressed against the arcuate portion 10n of 10b is held at that position, the adjustment position does not shift even if vibration or the like is applied to the remote control device main body 2 after the angle adjustment.

  When the angle adjustment of the signal transmission unit 12 is completed as described above, the upper case 4 is fitted on the upper surface of the middle case 5 as shown in FIG. 14, and a hemispherical transparent cover provided on the upper case 4 Since the signal transmission unit 12 is located within 4d, the upper case 4 does not prevent the infrared rays irradiated from the light emitting element 12b from arriving at the electric device 3, and the operation of the electric device 3 is reliably controlled by the remote control device. become able to.

  15 and 16 show a modification of the means for restricting the rotation angle of the movable part 10a of the angle adjusting means 10, and a stopper 10p is provided in the circular recess 6c of the lower case 6 as shown in FIG. In addition to projecting, an arc-shaped locking projection 10j centering on the pivot center of the movable portion 10a is projected on the flat plate 10h side of the angle adjusting means 10, and when the movable portion 10a is pivoted, When the end of the locking protrusion 10j abuts against the stopper 10p, the rotation angle of the movable part 10a is restricted to approximately 180 °. According to this modification, the arcuate guide groove 5e or The stopper pin 10m can be omitted.

  The remote control device of the present invention can adjust the transmission direction of the signal transmitted from the signal transmission unit provided in the movable part, so that the remote control of the electric equipment can be performed reliably, and the place where the remote control device is attached is limited. In addition, the remote control device can be easily installed, and can be configured with a small number of parts including a support member that rotatably supports a movable portion and a means that rotatably supports the support member.
