Description

  The present invention relates to a remote controller, in particular, when a casing in which a display and a push button are assembled is placed on a table surface, a floor surface, etc. in an inverted position, the push button is rubbed against the placement surface. The present invention relates to a remote controller in which measures are taken to prevent the characters from being peeled off, the push button being inadvertently pressed and malfunctioning, or the display being rubbed and scratched against a mounting surface or the like.

  In a general remote controller, a push button, a display, or the like is provided on one side of a casing, and characters are displayed on the push button by silk printing or the like. In such a remote controller, if the case is left on a mounting surface such as a table surface in an upside down posture, the push buttons may rub against the mounting surface and the display of characters may be peeled off or the display may be damaged. The user may feel uncomfortable.

On the other hand, conventionally, protrusions are provided at the four corners of the main body case of a wireless remote control device (remote control) used for remote control of the air conditioner, and an external switch provided with the main body case on the back is turned down. For example, a technique has been proposed in which the projections at the four corners contact the table surface and the outer switch does not contact the table surface when placed on a table or the like (see, for example, Patent Document 1). In remote control transmitters for selectively remotely controlling home appliances such as lighting equipment and various audiovisual equipment, a channel changeover switch is arranged near the center of a substantially flat operation face, and the operation face of the channel changeover switch is arranged. When the operation surface is placed on a flat surface such as a table, the operation key is lifted from the flat surface to prevent malfunctions. The technique of preventing was also proposed (for example, refer patent document 2). Furthermore, in the water heater remote control, guide pins are provided in the lower case to help prevent the liquid crystal display and connection pins installed in the lower case from being damaged in the production line of the remote control. Is known (see, for example, Patent Document 3).
Public Open Hei 6-2042 JP 2005-323075 A JP-A-11-132485

  Among the above-mentioned patent documents, according to the remote controller described in Patent Document 1, when the main body case is placed on a table or the like with the outer switch on the back face down, it is provided at the four corners of the main body case. Since the protrusion functions as a spacer and prevents the outer switch from contacting the table, etc., even if the character is displayed on the outer switch, the character may be rubbed and peeled off, or the outer switch It is thought that the situation where the system is accidentally pushed and malfunctions is prevented. However, in this remote control, the projections at the four corners of the main body case are only provided with spacer functions, so that if the main body case is formed with reinforcing ribs to reinforce the main body case, the reinforcing ribs Is inconvenient and inconvenient in that it must be formed separately from the protrusions.

  In addition, the remote control transmitter described in Patent Document 2 has a function that the channel changeover switch itself functions as a spacer when the operation surface is turned down and placed on a flat surface such as a table, and other operation keys are flat. If the channel selector switch is pushed in due to the force applied to the remote control transmitter, not only will the channel selector switch malfunction, but other operation keys may also be pushed in, causing malfunctions. There is a risk of doing so.

  Furthermore, in the water heater remote control described in Patent Document 3, the guide pins are only useful for preventing damage to the liquid crystal display and the connection pins only in the production line. It is not prevented by guide pins.

  The present invention has been made in view of the above situation, and the push button rubs against the mounting surface when the remote controller is placed on a mounting surface such as a table surface with the casing turned upside down. Not only can the characters on the surface peel off, the push buttons can be pushed inadvertently, cause malfunctions, and the display can be rubbed and scratched against the mounting surface, etc. It is an object of the present invention to provide a remote controller that exhibits the same reinforcing effect as the case where reinforcing ribs are provided on the case and the effect of reducing warping and sagging during molding.

  In the remote controller according to the present invention, a rectangular display play and a push button are arranged on one flat surface of a flat hollow box-shaped housing. And the said housing | casing is equipped with the bulging part formed by bulging a part of the one side, and when the housing | casing was mounted in the reverse posture, it sat down on the mounting surface The bulging portion functions as a spacer that lifts the display and the push button from the mounting surface, and the bulging portion is formed in an elongated shape to function as a reinforcing rib that reinforces the casing. It comes to show.

  According to the present invention, when the casing is placed in an upside down posture, the bulging portion that functions as a spacer that lifts the display and the push button from the placement surface is formed to be elongated. The part also functions as a reinforcing rib for reinforcing the casing. Therefore, the case itself will be reinforced by measures taken to prevent peeling of characters on the surface of the push button, malfunction of the push button, scratching of the display, etc. when the case is placed in an inverted position. Even when it is desired to reinforce the housing, there is no need to separately provide a reinforcing rib for that purpose. Further, the bulging portion exerts an effect of reducing warping and sagging during molding.

  In the present invention, the bulging portion is divided into a pair of front and rear ridges that cross one side of the casing in the width direction on both front and rear sides sandwiching the place where the display is disposed, and extend across the entire width of the one side. It is desirable to adopt a configuration that According to this, since the rectangular display is reinforced by the action as the reinforcing ribs of the pair of ridges positioned at the front and rear of the rectangular display, even if an unexpectedly large external force is applied to the housing, in general, This prevents a situation in which the display is damaged by applying a large force to the display having a relatively low strength.

  In the present invention, the housing is divided into a case main body provided with the display and a push button on one side and formed with the bulging portion, and a head case arranged on the front side of the case main body. The head case may be rotatably connected to a spindle attached to the front end of the case body.

  In the present invention, the push button is provided on the rear side of the display on one side of the case body, and the front ridge of the pair of front and rear ridges is the front end of the case body, and the one side of the case body is arranged in the width direction. The rear ridge extends across the entire width of the case body across one side of the case body between the display location of the display and the deployment location of the push button. It is possible to adopt a configuration that extends over the entire width, and according to this, as described above, the display acts as a reinforcing rib of a pair of ridges positioned before and after the display. In general, even if a large torsional action is added to the housing, a large force is applied to a display with a relatively low strength and it is generally damaged. So it is prevented.

  In the present invention, the outer surface of the ridge on the front side is formed in an arc shape in cross section, and the rotation path of the head case around the support shaft is an arc shape along the outer surface of the ridge on the front side. In addition, by adopting a configuration in which the installation position of the support shaft at the front end portion of the case body is determined, it becomes easy to determine the rotation range of the head case.

  The remote controller according to the present invention can employ the following specific configuration. That is, in a remote controller in which a rectangular display play and a push button are arranged on one flat surface of a flat hollow box-shaped housing, the housing is located on one side of the display and the rear side of the display. It is divided into a case main body having a push button and a head case arranged on the front side of the case main body, and the head case is rotatably connected to a support shaft attached to a front end portion of the case main body, On one side of the case body, an outer surface having an arcuate cross section located between the front protrusion having the outer surface with an arcuate cross section located at the front end of the case body and the deployment location of the display and the push button is provided. A bulging portion that is divided into rear ridges, and the front ridges and the rear ridges cross one side of the case body in the width direction. When the casing is placed on the front and rear ridges in an inverted position, the display and the push button are seated on the placement surface. A function as a spacer that floats from the mounting surface and a function as a reinforcing rib that reinforces the case body are provided, and the function as the spacer is the front ridge from one side of the case body and It is given to those front side ridges and back side ridges by making both protrusion heights of the rear ridges higher than the protrusion height of the push button, and the head case around the support shaft It is possible to adopt a configuration in which the installation position of the support shaft at the front end portion of the case body is determined so that the rotation path has an arc shape along the outer surface of the front ridge. The configuration and operation of the present invention will be described in detail with reference to embodiments described later.

  According to the present invention, the casing is placed in an inverted posture on the bulging portion formed on the flat one side of the flat hollow box-shaped casing in which the rectangular display play and the push button are arranged. Sometimes the display surface or push button is lifted from the mounting surface and functions as a spacer, and the function as a reinforcing rib to increase the strength of the housing itself. Even if a force in the pressing direction is applied to the case placed on the display, the display may rub against the placement surface and be damaged, the push button may malfunction, or the characters applied to the push button may be rubbed off Not only does not occur, but also the strength of the housing is increased without adding additional reinforcing ribs, and damage due to deformation of the display or the like is prevented. In addition, the effect | action which reduces the curvature and dripping at the time of shaping | molding is show | played. Therefore, according to the present invention, even if the casing is placed on a table surface or the like in an inverted position, the character display by silk printing applied to the push button is peeled off, the push button malfunctions, The display will not be scratched and the characters will not be unpleasant due to peeling or malfunctioning of those characters, as well as something placed on the case or the case. Even if an unexpected external force is applied to the display, it is generally easy to cause damage due to deformation, but the display is protected from such damage, and warping and sagging during molding are reduced. It helps to increase mass productivity.

  In particular, according to the bulging portion, it is divided into a pair of front and rear ridges extending across the entire width of one side across one side of the casing in the width direction on both sides before and after sandwiching the place where the display is placed. The effect of preventing display damage accidents is remarkably exhibited.

  This embodiment is an example of a remote controller as a so-called multi-remote controller. That is, the remote controller shown in this embodiment includes an authentication operation for authenticating the counterpart electric device by exchanging an optical signal with an adapter that outputs an identification signal unique to the counterpart electric device, It has a function of performing a normal operation for transmitting an optical signal to the counterpart electric device and controlling the counterpart electric device under an operation mode unique to the counterpart electric device set through the authentication operation. In this remote controller, when the authentication operation of the counterpart electric device is normally performed, the remote controller can be used as a dedicated remote controller for the counterpart electric device.

  FIG. 1 is a schematic plan view of a remote controller A according to an embodiment of the present invention, and FIG. 2 is a schematic side view of the remote controller A.

  As shown in FIGS. 1 and 2, in this remote controller A, the housing 1 is divided into a case main body 2 and a head case 3 arranged on the front side of the case main body 2. It is connected to the case main body 2 via a support shaft 4 attached to the main body 2. The head case 3 can be pivoted in a swinging state as indicated by an arrow R in FIG. 2 within a certain range with respect to the case main body 2 with a connection point by the support shaft 4 as a fulcrum. According to the remote controller A, when performing the authentication operation and the normal operation, a certain convenience for the user can be obtained by the swing operation of the head case 3.

  FIG. 3 is a longitudinal side view of the top case 22 forming the case body 2, and FIG. 4 is a plan view showing an example of the push button 200.

  As shown in FIGS. 1 and 2, the case main body 2 of the remote controller A of this embodiment is formed in a flat box shape, and the user performs the above-described authentication operation and normal operation by holding the case main body 2 by hand. . On the other hand, the head case 3 is formed with a width substantially the same as the width of the case body 2. In FIG. 1 and FIG. 2, a connecting portion between the case main body 2 and the head case 3 is indicated by a symbol C.

  As can be inferred from FIG. 2, the case body 2 is divided into a bottom case 21 and a top case 22, and a flat box-shaped case body 2 is formed by connecting both the screws 21 and 22 with screws. It is like that. The case main body 2 is assembled with a display 100, a push button 200, and the like formed of a liquid crystal module. The case body 2 is provided with a battery box that houses the battery B, and a lid 23 that opens and closes the battery box is detachable from the case body 2.

  As shown in FIG. 1 and FIG. 2, in the remote controller A according to this embodiment, the rectangular display 100 and the push button 200 described above are arranged on one flat surface of the case body 2. Located on the back side. Further, while the push button 200 slightly protrudes from the flat one surface of the case body 2, the surface of the display 100 is flush with the flat one surface of the case body 2 or slightly retracts from the one surface. positioned.

  The case body 2 is provided with a bulging portion 6 formed in the top case 22. In this embodiment, the bulging portion 6 is divided into front ridges 61 and rear ridges 62 located at two front and rear positions on one side of the top case 22 corresponding to one side of the case body 2. The front ridge 61 is positioned at the front end of the case body 1, and the rear ridge 62 is positioned between the deployment location of the display 100 and the deployment location of the push button 200. Further, the front ridges 61 and the rear ridges 62 extend across the entire width of one side of the top case 22 across the width direction.

  As shown in FIG. 3, each of the ridges 61 and 62 has an outer surface in a circular arc shape. In addition, by determining the thickness of each of the ridges 61 and 62 to be substantially the same as the thickness of the other portions of the top case 22, it can be caused by the difference in thickness at the molding location of each ridge 61 and 62. The occurrence of so-called “retreat” is suppressed. In addition, when the thickness of each of the ridges 61 and 62 is set to be substantially the same as the thickness of the other portions of the top case 22 in this way, warpage and sagging at the time of molding are reduced, so that mass productivity is improved. . Furthermore, each protrusion 61, 62 has a protruding height from one side of the case body 2 higher than the protruding height of the push button 200 from one side of the case body 2, and FIG. The difference H is indicated by the symbol H.

  In the remote controller A according to this embodiment, the front ridges 61 and the rear ridges 62 as the bulging portions 6 formed at two positions on the front and back sides of the case body 2 function as spacers. A function as a reinforcing rib is provided. Among these, the function as a spacer is that when the remote controller A is placed on the table surface or the like in the inverted position, the display 100 or the push button 200 provided on one side of the case body 2 is used as the table surface or the like. It is a function to lift and hold from the mounting surface. Moreover, the function as a reinforcing rib is a function which raises the rigidity of the case main body 2 and suppresses the bending deformation of the case main body 2 when an external force is applied.

  In this embodiment, as described with reference to FIG. 3, the functions of the front ridges 61 and the rear ridges 62 as the spacers are the heights of the projections of the front ridges 61 and the rear ridges 62. This is achieved by making the height of the push button 200 higher than the protruding height of the push button 200 and making the height of the two different from each other. That is, when the remote controller is placed on the placement surface P in an inverted posture, the front ridges 61 and the rear ridges 62 are seated on the placement surface P, as can be seen from FIG. The display 100 and the push button 200 shown in FIGS. 1 and 2 are held while being lifted from the placement surface P. Therefore, even if the remote controller slides on the placement surface P, the display 100 and the push button 200 are not rubbed against the placement surface P, and there is no possibility that the display 100 and the push button 200 are damaged. . In this regard, as shown in FIG. 4, numbers, symbols, and other characters may be displayed on the top surface of the push button 200 by silk printing. Even in this case, as described above, the push button 200 is also displayed. Does not rub against the mounting surface P, and there is no fear that the display 201 rubs against the mounting surface P and peels off. For these reasons, the person using the remote controller A feels discomfort caused by the display 100 or the push button 200 being damaged, or discomfort caused by the display 201 applied to the push button 200 being peeled off. Without using the remote controller A.

  Further, the function of the front protrusions 61 and the rear protrusions 62 as the reinforcing ribs suppresses the bending deformation of the case body 2 when the rigidity of the case body 2 is increased and an external force is applied. For this reason, even if the liquid crystal module forming the display 100 is relatively easily damaged by an external force, the external force applied to the case body 2 acts as a reinforcing rib for the front ridge 61 and the rear ridge 62. The function prevents the liquid crystal module from being added and protects the liquid crystal module. In particular, in this embodiment, a function as a reinforcing rib is imparted to the front ridges 61 and the rear ridges 62 that exhibit the functions as the spacers described above, and the front ridges 61 and the rear ridges are provided. Since the ridges 62 are provided before and after the display 100 is sandwiched, there is an advantage that the function of protecting the liquid crystal module forming the display 100 is remarkably exhibited even though no reinforcing rib is provided. is there.

  Next, in this embodiment, the deployment position of the support shaft 4 connecting the head case 3 to the case body 2 is positioned substantially concentric with the center position of the arc surface of the outer surface of the front ridge 61. For this reason, the rotation path of the head case 3 around the support shaft 4 has an arc shape along the outer surface of the front protrusion 61. In this way, the situation where the head case 3 hits the front ridge 61 and the rotation range thereof is narrowed does not occur, and the rotation range of the head case 3 is that of the front ridge 61 as shown by the arrow R in FIG. It is expanded to the range including the surroundings.

  In the above-described embodiment, considering that the remote controller A is a multi-remote controller having a function of performing an authentication operation of the electric device and a normal operation of the electric device, the case 1 is replaced with the case main body 2 and the head case 3. However, the remote controller according to the present invention may be one in which the housing 1 is not divided into the case main body 2 and the head case 3. That is, a display or a push button may be provided on one side of one flat box-shaped case. In that case, the function as a spacer and the function as a reinforcing rib are provided on one side of the case. What is necessary is just to provide the bulging part which exhibits. Further, the bulging portion 6 is not necessarily divided into the front ridges 61 and the rear ridges 62 as described in the embodiment. For example, it may be formed in a rectangular frame shape surrounding the periphery of the display.

  In FIG. 1 to FIG. 4, common parts are denoted by the same reference numerals or corresponding parts.

It is a schematic plan view of the remote controller A of the embodiment according to the present invention. It is a schematic side view of the remote controller A. It is a vertical side view of the top case which forms the case main body. It is the top view which showed an example of the push button.
