Description

  The present invention relates to an input operation device including a pressing operation body arranged in the center and one or more pressing operation bodies arranged around the pressing operation body.

  Conventionally, provided with a plurality of pressing operation bodies and an operation panel having an opening through which the operation surfaces of the plurality of pressing operation bodies can be exposed, the plurality of pressing operation bodies are a central operation body arranged at the center of the opening, There is known an input operation device including a peripheral operation body arranged around a central operation body (Patent Document 1). When the end of the operation surface of the pressing operation body is pressed, the pressing operation body is inclined obliquely with respect to the operation panel. If the pressed operating body is tilted obliquely, it becomes difficult to obtain a stable touch operation, and the operation becomes uncomfortable.

  In order to suppress tilting of the pressing operation body, it is known to provide a protruding edge (flange) that protrudes from the peripheral edge of the pressing operation body. Thereby, when the pressing operation body is inclined obliquely, the flange comes into contact with the peripheral portion of the pressing operation body, for example, the wall portion of the opening where the operation surface of the pressing operation body is exposed, and further inclination can be suppressed.

JP 2003-257279 A

  However, in the case where a flange is provided on the central operating body of the input operating device configured as in Patent Document 1, when the surrounding operating body is pressed, the flange of the central operating body is pushed by the surrounding operating body, The body is also pushed in the pressing direction, and operates as if the central operating body is pressed together with the surrounding operating body. Therefore, in such an input operation device, the central operation body cannot be provided with a flange, and the inclination of the central operation body cannot be suppressed.

  Accordingly, the present invention includes a central operation in which a plurality of pressing operation bodies and an operation panel having an opening through which an operation surface of the plurality of pressing operation bodies can be exposed are provided, and the plurality of pressing operation bodies are arranged at a central portion of the opening. In an input operation device composed of a body and one or more surrounding operation bodies arranged around the central operation body, an input operation device capable of suppressing the inclination of the central operation body with respect to the operation panel when the central operation body is pressed The purpose is to provide.

The present invention includes a plurality of pressing operation bodies and an operation panel having an opening through which an operation surface of the plurality of pressing operation bodies can be exposed, and the plurality of pressing operation bodies are arranged at a central portion of the opening. And an input operation device having one or more peripheral operation bodies arranged around the central operation body,
Located on the back side of the operation surface of the operation panel and on the outside of the surrounding operation body, provided with a support part for supporting the central operation body, the support part is formed in a rectangular frame shape, the central operation body, A side where the central operating body is connected to a part of the central operating body, supports the central operating body, and the central operating body can be moved in the pressing direction by bending, and a side where the supporting arm of the central operating body is connected and a tilt suppressing arm extending on the side opposite to the inclination suppressing arm, and supported at one end on the support portion to the other end of the opposite side, protruding toward the front from the back side of the operation surface of the operation panel With protrusions ,
The support arm is formed in two thin and elongated shapes, extends from the central operating body to one side in the longitudinal direction of the support portion, and is continuous with the inner peripheral wall of the support portion.
The tilt suppression arm is formed in two elongated shapes having a thickness larger than that of the support arm, is connected to the outer peripheral wall of the central operating body, and is arranged on the other side in the longitudinal direction of the support portion at the end of the inner peripheral wall of the support portion. Extending towards the
The support arm and the tilt suppression arm are arranged symmetrically on a diagonal line of the support portion .

According to the present invention, when the end of the central operation body that is connected to the support arm is pressed, the protrusion of the tilt suppression arm contacts the back side of the operation surface of the operation panel outside the surrounding operation body. Therefore, the inclination of the central operating body can be suppressed. In addition, when the end of the central operating body that is connected to the tilt suppressing arm is pressed, the tilt of the central operating body can be suppressed by the support arm supported by the support portion formed in a rectangular frame shape . As described above, when the end side of the central operating body is pressed, the tilt of the central operating body can be suppressed by the support arm, the inclination suppressing arm, and the protrusion.

  In the present invention, it is preferable that the support arm and the tilt suppression arm are composed of two or more, and the arms are arranged so that the intervals between all the arms of the support arm and the tilt suppression arm are equal. When the end of the central operating body is pressed, a force in the direction opposite to the pressing direction acts on the end of the central operating body opposite to the pressed side. Accordingly, the support arm having the function of suppressing the tilt of the central operation body and the tilt control arm are arranged so that the distance between them is equal, so that the central operation body is compared with the one in which the distance between each other is biased. The inclination of the can be effectively suppressed.

  When the intervals between the arms of all the arms are biased, there is a range in which the inclination of the central operation body between the arms can be suppressed, and the efficiency of suppressing the inclination of the central operation body with respect to the number of arms is deteriorated. For this reason, this ratio is improved by equalizing the distance between all arms of the support arm and each arm of the tilt suppression arm, and the tilt is most efficiently suppressed when the same number of arms are used. Can do.

  Therefore, by configuring the support arm and the tilt suppression arm with two or more and arranging the intervals of all the arms to be equal, compared to the support arm and the tilt suppression arm configured with one, When the end of the central operating body is pressed, the ratio of the end capable of suppressing the tilt of the central operating body can be increased more effectively. Here, “arranged so that the intervals are equal” does not necessarily have to be arranged at the same rate, as long as it is arranged to increase the rate of suppressing the inclination of the central operating body. Well, including those arranged in slightly different proportions.

To do.

  The support portion 5 is formed of a synthetic resin in a rectangular frame shape, and the frame is on the back surface side (hereinafter referred to as “back surface”) 22 side of the operation surface 21 of the operation panel 2 and the surrounding operation bodies 4 a to 4. It arrange | positions so that it may be located outside 4d. That is, the frame of the support part 5 is located outside the central operation body 3 or the surrounding operation bodies 4a to 4d when viewed from the operation surface side toward the back surface side. As shown in FIG. 2, the surrounding operation bodies 4 a to 4 d are arranged between the operation panel 2 and the support portion 5.

  The support arms 6a and 6b are made of synthetic resin and are formed in a thin and long shape. The support arms 6a and 6b are integrally formed with the central operation body 3 and the support portion 5, and one end is connected to a part of the support portion 5 on the right side in FIG. Further, the other ends of the support arms 6a and 6b are connected to a part of the outer peripheral wall on the right side in FIG. Specifically, one end of the support arm 6a is connected to the upper right side of the inner peripheral wall of the support portion 5, and the other end is connected to the upper right side of the outer peripheral wall of the central operating body 5, and one end of the support arm 6b is connected. Is connected to the lower right side of the inner peripheral wall of the support portion 5, and the other end is connected to the lower right side of the outer peripheral wall of the central operating body 5.

  The inclination suppression arms 7a and 7b are made of synthetic resin and are thicker than the support arms 6a and 6b, and are formed in an elongated shape. The tilt suppression arms 7a and 7b are formed integrally with the central operation body 3, and one end is opposite to the side where the support arms 6a and 6b supporting the central operation body 3 are connected (left side in FIG. 4). It is connected to.

  Specifically, one end of the tilt suppression arm 7 a is continuous with the upper left side of the outer peripheral wall of the central operation body 5, and one end of the tilt suppression arm 7 b is continued with the lower left side of the outer peripheral wall of the central operation body 5. Further, protrusions 7c and 7d projecting from the back side of the operation surface 21 toward the front side (from the lower side to the upper side in FIG. 3) are formed at the other ends of the inclination suppressing arms 7a and 7b.

  The tilt suppression arms 7a and 7b are arranged symmetrically with respect to the support arms 6a and 6b with the central operating body 3 as the center, and the arms of the support arms 6a and 6b and the arms of the tilt suppression arms 7a and 7b are arranged. All the arms are arranged so that the distance between them is almost equal.

  Next, the operation of the input operation device 1 having the above configuration will be described with reference to FIG. 5 is a cross-sectional view taken along the line V-V of FIG. 1. FIG. 5A shows a state where the central operating body 3 is not pressed, and FIG. 5C, and FIG. 5C shows the central operating body 3, the tilt restraining arms 7a and 7b, the support portion 5 and the operation panel 2 when the side of the operating surface of the central operating body 3 on which the supporting arm is connected is pressed. FIG.

  When the central operating body 3 is not pressed, as shown in FIG. 5A, the extended surface of the operating surface of the central operating body 3 and the extended surface of the operating panel 2 are substantially in the same plane. At this time, the protrusions 7c and 7d of the inclination suppressing arms 7a and 7b are in contact with the back surface 22 of the operation panel 2. At this time, no force acts between the protrusions 7 c and 7 d and the operation panel 2.

  When the central portion of the operation surface of the central operating body 3 is pressed, that is, when a force along the pressing direction is applied to the central operating body 3, as shown in FIG. 3 is pushed without being inclined with respect to the operation panel 2 while being kept substantially parallel.

  When the side (right side in FIG. 5) supported by the support arms 6a and 6b of the operation surface of the central operating body 3 is pressed, that is, a force in a direction inclined with respect to the pressing direction is applied to the central operating body 3. 5C, the central operating body 3 is farther from the operation panel 2 on the side where the support arms 6a and 6b are connected than on the side where the inclination suppression arms 7a and 7b are connected. In this case, a force is applied to tilt (in the case of FIG. At this time, a force from the back surface 22 side to the operation surface 21 side (from the lower side to the upper side in FIG. 5) acts on the end of the central operating body 3 on the side where the tilt support arms 7a and 7b are connected.

  However, since the protrusions 7c and 7d are in contact with the back surface 22 of the operation panel 2, the reaction of the operation panel 2 causes the protrusions 7c and 7d to move from the operation surface 21 side to the back surface 22 side (upper side in FIG. 5). To the bottom). As a result, the central operating body 3 is pushed toward the pressing direction (lower side in FIG. 5) while the inclination is suppressed.

  Further, when the side (the right side in FIG. 5) where the tilt suppressing arms 7a and 7b of the operation surface of the central operation body 3 are pressed is pressed, that is, the force in the direction inclined to the central operation body 3 with respect to the pressing direction. Is added, the central operating body 3 tilts with respect to the operating panel 2 such that the side where the tilt suppressing arms 7a, 7b are connected is farther from the operating panel 2 than the side where the supporting arms 6a, 6b are connected ( In the case of FIG. 5, the force is applied to the left shoulder. At this time, a force from the back surface 22 side to the operation surface 21 side (from the lower side to the upper side in FIG. 5) acts on the end of the central operation body 3 on the side where the support arms 6a and 6b are connected.

  However, since the support arms 6a and 6b are supported by the support portion 5, the end of the central operating body 3 on the side where the support arms 6a and 6b are connected is connected to the operation surface 21 side so as to suppress this force. The force from the back surface 22 side (from the upper side to the lower side in FIG. 5) works. As a result, the central operating body 3 is pushed toward the pressing direction (lower side in FIG. 5) while the inclination is suppressed.

  In the input operation device 1 of the present embodiment configured as described above, even the central operation body 3 surrounded by the pressing operation body is added to the support arms 6a and 6b that support the central operation body 3, By forming the inclination suppressing arms 7a and 7b, the inclination of the central operating body 3 when the end side of the central operating body 3 is pressed can be suppressed. Specifically, when the end side of the central operating body 3 that is connected to the support arms 6a and 6b is pressed, the protrusions 7c and 7d of the inclination suppressing arms 7a and 7b are outside the surrounding operating bodies 4a to 4d. Therefore, the tilt of the central operating body 3 can be suppressed. Further, when the end side of the central operating body 3 that is connected to the tilt suppressing arms 7 a and 7 b is pressed, the tilt of the central operating body 3 can be suppressed by the support arms 6 a and 6 b supported by the support section 5. As described above, when the end side of the central operation body 3 is pressed, the inclination of the central operation body 3 can be suppressed by the support arms 6a and 6b, the inclination suppression arms 7a and 7b, and the protrusions 7c and 7d.

  In the present embodiment, the support arms 6a and 6b are formed in a thin and elongated shape. As a result, the central operating body 3 is supported and is easily bent so that it can be pushed in the pressing direction. Further, when the length of the support arms 6a and 6b is short, it becomes difficult to bend as compared with a long one having the same thickness, and the force required for pressing increases, so that pressing becomes difficult.

  Similarly, when the thickness of the support arms 6a and 6b is large, it becomes difficult to bend compared to a thin one having the same length, and it is difficult to press because the force required for pressing increases. If the support arms 6a and 6b are formed thin in order to prevent the central operating body 3 from being hard to be pressed, the durability is low, and there is a high possibility of damage such as breaking even when the number of times of pressing is small. Become. For this reason, by forming the support arms 6a and 6b as long as possible in the layout of the parts, a certain thickness is ensured and durability is improved, and the operability of the pressing operation body is improved by being easily bent. .

  In the present embodiment, the inclination suppression arms 7a and 7b are thicker than the support arms 6a and 6b. As described above, the support arms 6a and 6b have a function of supporting the central operating body 3, and are required to be pushed in the pressing direction when pressed, so that the supporting arms 6a and 6b are formed thin so as to be easily bent. .

  On the other hand, the tilt suppression arms 7a and 7b do not need to support the central operating body 3, and only need to prevent tilting by contacting the back surface 22 when the central operating body 3 tilts. Therefore, the inclination suppression arms 7a and 7b do not need to be easily bent. Rather, the tilt suppression arms 7a and 7b are required to have a certain degree of strength so that the tilt can be prevented by contacting the back surface 22. For this reason, the durability of the inclination suppression arms 7a and 7b can be improved by forming the inclination suppression arms 7a and 7b to be thicker than the support arms 6a and 6b.

  In the present embodiment, the arms of the support arms 6a and 6b and the arms of the inclination suppression arms 7a and 7b are arranged so that the distances between all the arms are substantially equal. When the end of the central operating body 3 is pressed, a force opposite to the pressing direction acts on the end of the central operating body 3 on the side opposite to the pressed side. Accordingly, the support arm 6a, 6b having the function of suppressing the tilt of the central operating body 3 and the tilt suppressing arms 7a, 7b are arranged so that the distance between them is equal, thereby effectively reducing the tilt of the central operating body 3. The ratio of the edge part which can be suppressed increases.

  That is, when the distances between the arms 6a, 6b, 7a, and 7b are biased, each arm has a range in which the inclination of the central operating body 3 can be suppressed, and the central operating body 3 has a range corresponding to the number of arms. The proportion of the edge gets worse. This ratio is improved by making the intervals of all the arms of the support arms 6a and 6b and the arms of the inclination suppression arms 7a and 7b equal. Can be suppressed.

  In the present embodiment, the protrusions 7c and 7d are in contact with the back surface 22 of the operation panel 2 even when the central operation body 3 is not pressed, but may not be in contact. . In this case, when the side (right side in FIG. 5) supported by the support arms 6a and 6b of the operation surface of the central operation body 3 is pressed, the operation arms are supported by the support arms 6a and 6b of the central operation body 3. The tilting arm 7a, 7b is tilted so that it is farther from the operation panel 2 than the side where the tilt suppression arms 7a, 7b are connected (in the case of FIG. 5, it is tilted to the right shoulder), and the projections 7c, 7d The central operating body 3 is tilted until it comes into contact with the center operating body 3.

  After the protrusions 7c and 7d abut against the back surface 22, the central operating body 3 is pushed in the pressing direction while maintaining this inclination. Therefore, if the inclination of the central operation body 3 is such that the operation does not feel uncomfortable, the distance between the protrusions 7c and 7d when the central operation body 3 is not depressed and the back surface 22 of the operation panel 2 is provided. It may be done.

  In the present embodiment, the support arms 6 a and 6 b and the inclination suppression arms 7 a and 7 b are formed integrally with the central operation body 3, but are formed of different members and connected to the central operation body 3. It may be configured. Even in this case, the effect of the present invention that the inclination of the central operating body 3 can be suppressed is obtained.

  In the present embodiment, the support arms 6a and 6b and the inclination suppression arms 7a and 7b are arranged so as to be symmetric with respect to the central operation body 3, but this is not restrictive. Even if it is not arranged symmetrically, the effect of the present invention that the inclination of the central operating body 3 can be suppressed is obtained. Thus, the present invention can be applied even in a case where it cannot be arranged symmetrically due to the part layout.

  Further, in the present embodiment, the support arms 6a and 6b and the inclination suppression arms 7a and 7b are each formed in two, but this is not restrictive, and there may be one or three or more. At this time, the number of support arms and tilt suppression arms may be different. However, when one support arm is disposed on the right side of the central operation body 3 and one tilt suppression arm is disposed on the left side of the central operation body 3, the support arm and the tilt suppression arm of the central operation body 3 are connected. When the vicinity of the end on the opposite side of the side being pressed is pressed down, the tilt can be effectively suppressed.

  In addition, even when three support arms are arranged on the right side of the central operation body 3 and three inclination suppression arms are arranged on the left side of the central operation body 3, the inclination of the central operation body 3 can be suppressed. In addition, since the forces acting on the support arm and the tilt restraining arm at the time of pressing are dispersed, the durability of these arms can be improved as compared with the present embodiment.

  In the present embodiment, the arms of the support arms 6a and 6b and the arms of the inclination suppression arms 7a and 7b are arranged so that the distances between all the arms are equal. Here, “arranged so that the intervals are equal” does not necessarily have to be arranged at the same rate, but may be arranged to increase the rate of suppressing the inclination of the central operating body 3. What is necessary is just to include what is arrange | positioned in a slightly different ratio.
