Description

  The present invention relates to a button unit and a thin display device.

  Generally, when a thin display device such as a liquid crystal television is moved (for example, when the installation location is changed or when a swivel operation is performed) or when cleaning is performed, the vicinity of the operation button may be grasped or pushed. At this time, the cabinet around the operation buttons may be deformed, resulting in a malfunction that is not intended by the user.

  Various techniques for preventing such deformation have been proposed. For example, an electrical device with an operation button attached to a cabinet has a structure in which a push button fits into the button hole on the front part and protrudes, while leaving a gap between the support part of the operation button and the cabinet front part. Furthermore, there is an electric device characterized in that the tip of the substrate attached to the bottom of the cabinet is placed on and supported by the substrate support (for example, see Patent Document 1). In this technology, by leaving a gap between the cabinet and the button support part, it is possible to attach the operation button in the same manner even when the front part or the button is inclined within the gap.

JP 2005-243399 A

  By the way, in the technique disclosed in Patent Document 1, it is assumed that the front portion (cabinet) bends within a gap. However, in recent thin display devices, particularly thin televisions such as liquid crystal televisions, the deflection of the cabinet is larger than before due to the thinning of the cabinet. Therefore, when an external force is applied to the cabinet, a deflection exceeding the gap occurs, and the button support portion is directly pressed. For this reason, there was a problem that the button was pushed directly and the button malfunctioned.

  Here, FIG. 5 schematically shows the state of the internal structure in which the button unit 150 conventionally used is disposed on the side surface 132 of the cabinet of the display unit main body 130. As shown in FIG. 5A, a button body 156 provided on the side surface 132 of the cabinet projects to the outside so as to be operable. The button main body 156 is provided on a button beam portion 154 formed so as to be cantilevered from the button base portion 152. 5B, when the button main body 156 is operated, the internal pressing portion 158 provided on the side opposite to the button main body 156 presses the substrate button 192 of the button substrate 190. However, as shown in FIG. 5 (c), even when the vicinity of the vicinity where the button main body 156 protrudes is pressed, the portion is greatly bent and the button beam portion 154 is pushed, and a malfunction may occur. .

  This invention is made | formed in view of the above situations, Comprising: It aims at providing the technique which solves the said subject.

The button unit of the present invention is provided on the free end side of the cantilever, and is operatively protruded from an opening provided in the cabinet, and is provided on the fixed end side of the cantilever, and the opening of the cabinet. And a protrusion provided to protrude toward the inner surface side in the vicinity.
The cantilever includes a pressing portion that presses a pressed component on a substrate on the free end side opposite to the area where the button main body is provided, and the button main body is operated to operate the cantilever. The beam may be bent and the pressing portion may act on the pressed component.
Further, the protruding portion may contact the inner surface of the cabinet in a state where the user does not operate the button body.
The thin display device of the present invention includes the above button unit on the upper and lower surfaces or side surfaces of the cabinet of the display unit main body.

  According to the present invention, it is possible to provide a technique for preventing the operation button from malfunctioning.

It is the front view, side view, bottom view, and top view which show the button unit based on embodiment. It is a figure which shows typically the state by which the button unit was operated based on embodiment. It is a figure which shows typically the state of the internal structure where the button unit based on a prior art is arrange | positioned at the side part of a cabinet.

  Next, modes for carrying out the present invention (hereinafter, simply referred to as “embodiments”) will be specifically described with reference to the drawings.

  1A and 1B are views showing the appearance of a liquid crystal television 10 according to the present embodiment, in which FIG. 1A is a front view, FIG. 1B is a side view, and FIG. 1C is a plan view (viewed from above). Figure). As illustrated, the liquid crystal television 10 has a structure in which a display unit main body 30 is attached to a stand 20. Furthermore, the liquid crystal television 10 is provided with a button unit 50 on a side surface 32 of a cabinet (housing) 31 of the display unit main body 30 as shown in a region X of FIGS. 1B and 1C. Here, seven button bodies 56 (see FIG. 2) of the button unit 50 are provided so as to be operable.

  FIG. 2 is a perspective view of the button unit 50, and FIG. 2B is an enlarged view of a part of the region Y in FIG. 3A is a front view of the button unit 50, FIG. 3B is a side view, FIG. 3C is a bottom view, and FIG. 3D is a plan view. Note that front / rear / up / down / left / right notation in the figure is the same as front / rear / up / down / left / right of the liquid crystal television 10. Further, FIG. 4 schematically shows the structure of the button unit 50 as viewed from above.

  As shown in the figure, the button unit 50 is, for example, a resin molded product whose vertical direction is the longitudinal direction, and includes a button base portion 52, a button beam portion 54, a button main body 56, and a protruding portion 60.

  Specifically, a button beam portion 54 provided at the left rear corner of the button base 52 is formed in a cantilever shape so as to extend forward by a predetermined length. That is, the left rear corner of the button base 52 is a fixed end and the front side is a free end. And the button main body 56 is formed in the free end side of the button beam part 54 toward the left side. A space is formed on the right side of the button body 56, that is, on the inner side of the button unit 50 so that the button substrate 90 can be disposed. As shown in FIG. 4, a button button 90 is pressed on the button substrate 90 by the operation of the button body 56 so that a predetermined operation can be detected.

  Here, the button main body 56 is formed so as to be supported at two upper and lower portions with two button beam portions 54 as a set. When the button unit 50 is disposed inside the display unit body 30, the button body 56 protrudes from the button opening 34 by a predetermined length and can be operated by the user.

  In addition, an internal pressing portion 58 is formed to protrude inward with a predetermined length at the center of the end portion on the side opposite to the operated side of the button body 56 (inside of the button unit 50). The internal pressing portion 58 presses the substrate button 92 in accordance with the operation on the button main body 56. That is, when the button main body 56 is operated, the button beam portion 54 is bent to the left, that is, the inner direction of the button unit 50, and the inner pressing portion 58 at the tip moves to the right side (inner side) to press the substrate button 92. . The number of the button beam portions 54 and the position of the internal pressing portion 58 can be set as appropriate.

  Furthermore, as one of the characteristic structures in the present embodiment, a protrusion 60 is provided in order to realize a function of preventing an erroneous operation on the button unit 50.

  Specifically, between the two button main bodies 56, the protrusion 60 protrudes from the position where the button beam portion 54 is formed toward the projecting direction of the button main body 56, that is, toward the left side in the drawing, and has a rib shape. Is formed. Here, a total of six protrusions 60 are formed as so-called contact ribs. Moreover, although the protrusion part 60 is formed in the position between the root parts of the button beam part 54, you may form in the root part of the button beam part 54 instead of between.

  Unlike the button beam portion 54, the protruding portion 60 is fixed to the button base portion 52 in a rigid manner. That is, the button body 56 is formed integrally with the button base 52 without being bent like the button beam portion 54. Then, in a state where the button unit 50 is installed inside the display unit main body 30, the tip portion of the protrusion 60 abuts against the cabinet inner surface portion of the side surface 32 of the display unit main body 30.

  In addition, when the separation distance of the projection part 60 and a cabinet inner surface part is the minimum, it shall be in contact substantially. Further, the installation position of the protrusion 60 is provided at a position where deformation such as bending does not occur substantially even if a force is applied to the protrusion 60 in relation to the structure of the button base 52 and the like.

  Therefore, as shown in FIG. 4B, even if an external force is applied to the hinge portion (button beam portion 54) of the button unit 50 provided inside the liquid crystal television 10 from the portion indicated by the region Z, the protruding portion 60 does not move. Therefore, even if the cabinet 31 near the button body 56 is deformed, the cabinet 31 does not reach the button beam portion 54. In other words, the force that bends the button beam portion 54 toward the board button 92 does not act. As a result, the substrate button 92 is not pressed by the action on the cabinet 31, and malfunction can be prevented.

  The present invention has been described based on the embodiments. This embodiment is an exemplification, and it is understood by those skilled in the art that various modifications can be made to combinations of the respective components and the like, and such modifications are within the scope of the present invention. For example, the button unit 50 is provided on the side surface 32, but may be provided on another surface.
