Description

  The present invention relates to an electronic device such as a DVD (Digital Versatile Disk) player equipped with a flat display panel, and more particularly to an electronic device that can position the display surface of the display panel with respect to the device body with good operability.

  2. Description of the Related Art Conventionally, in an electronic device such as a DVD player in which a reproduced video signal is displayed on a display means and a program is viewed, a television receiver is used as the display device, and the device main body is used exclusively at home. Stationary equipment was common.

  However, as a display means, for example, a lightweight and thin flat display panel using liquid crystal has been put into practical use, and products in which an electronic device that handles video signals and a flat display panel are combined are also appearing on the market.

  Such an electronic device provided with a flat display panel can be reduced in size and weight, and thus can be used not only at home but also outdoors such as in a train.

  As usage, in the home, place the device on a desk and watch it sitting on a chair, or place it on a tatami mat or carpet and lie on it, or even watch it on a wall. Can be used.

  When sitting outdoors on a train seat, park bench, etc., you can use the device by placing the device on your lap or watching it while standing or holding it in your hand.

  As described above, since the usage forms are various, it is preferable that the flat display panel is not fixed to the apparatus main body, but the angle and position can be freely set within a predetermined range.

  Conventionally, for example, in Patent Document 1, in an image display device provided with a flat display panel, a speaker box and a display unit are coupled by two hinges so that the angle of the display unit with respect to the speaker box can be freely set. Proposals have been made.

In the case of this patent document 1, although it is comprised so that the angle of a display part can be adjusted with two hinges, it cannot necessarily be said that usability is favorable. That is, in order to easily and surely adjust to the target angle, it is preferable that the hinge is configured to be rotatable with a light torque. On the other hand, in order to securely hold the adjusted position, a large torque is required. Although it is important to make the structure that satisfies the contradictory conditions, it is important to make the hinge that can be rotated at the same time, but such a point is not described and there is room for further improvement.
Japanese Patent Laid-Open No. 2001-78122 (pages 2, 3 and 1, 2, 3)

  As described above, conventionally, in an apparatus in which a flat display panel is combined with an electronic apparatus main body so that the angle and position can be freely set, the angle and position can be easily adjusted. However, a configuration that satisfies the contradictory condition of maintaining the adjusted state stably improves usability, so that it is desired to be realized. However, there are still proposals that have realized it. Absent.

  The present invention has been made in view of the above points. The hinge that couples the device main body and the flat display panel is configured to vary the rotational torque in accordance with the rotational direction, and the angle and position. It is an object of the present invention to provide an electronic device capable of realizing easy adjustment and reliable holding of the adjusted angle and position.

  An electronic apparatus according to the present invention includes a display unit that displays a video signal as an image, a device main body that provides the video signal to the display unit, and a display unit and a device main body provided at both ends. And a leg that allows adjustment of at least an angle of the display unit with respect to the device main body by being connected via a second hinge, and one or both of the first and second hinges, And a torque adjustment mechanism that varies the rotation torque according to the rotation direction.

  The electronic device of the present invention is provided with a display unit that displays a video signal as a video, a device main body that provides the video signal to the display unit, and the display unit and the device main body at both ends. A leg that allows adjustment of at least an angle of the display unit with respect to the device main body by being connected via the first and second hinges, and either one of the surface of the device main body or the end of the display unit; A limiting mechanism member that is formed by protrusions formed on both sides and restricts the contact between the surface of the device main body and the end of the display unit to the protrusions is provided.

  According to the present invention, in an electronic device in which the device main body and the display unit are connected by the first and second hinges so that the angle and position of the display unit with respect to the device main body can be adjusted, the surface of the device main body or the display unit Since the limiting mechanism member that restricts the contact of the display unit end to the device main body is provided on one or both of the end portions of the display unit, the entire surface of the device main body may be damaged at the end of the display unit. Accidents can be prevented.

  Furthermore, when either or both of the first and second hinges are rotated in the direction to open the angle of the display unit with the device main body, it can be executed with a small force and rotated in the opposite direction. In this case, since a large force is required, the display unit can be quickly and easily positioned at a target angle, and the position can be stably secured.

  Further, since at least the first hinge is provided with a mechanism for locking the position of the first hinge when the display unit is rotated to the position where the display unit is opened at the largest angle from the device body, the device body is mounted on the wall surface. Even in a state where the display unit is fixed and used, it is possible to prevent the display unit from falling forward.

Hereinafter, an embodiment of an electronic apparatus of the present invention will be described in detail with reference to the drawings.
FIG. 1 is a perspective view of an electronic device 100 of the present invention, and FIG. 2 is a view of the electronic device 100 as viewed from the side. As shown in the figure, an electronic device 100 includes an electronic device main body 101 configured by, for example, a DVD player, and a display unit 102 including a flat display panel attached to the electronic device main body so as to be rotatable by a hinge. Composed. The electronic device 101 sends a video signal for display to the display unit 102, and the display unit 102 displays a video based on the video.

  The electronic device main body 101 derives sound from an optical disk mounting unit 103 on which an optical disk as a DVD recording medium is mounted, an operation unit 104 operated by a user to execute various operations of the device main body, and a speaker (not shown). An opening 105 is provided for this purpose.

  Furthermore, rim portions 106 for supporting the end of the display unit 102 are provided at both ends of the upper surface of the electronic device main body 101 so as to protrude from the surface.

  The display unit 102 has protrusions 108 formed at both lower ends of the frame 107 so as to face the rim 106 of the device main body 101, and a remote controller (not shown) is formed below the frame 107. A remote control signal receiving unit 109 for receiving a remote control signal from is provided.

  As shown in FIG. 2, a leg 201 is disposed between the device main body 101 and the display unit 102, and the leg 201 and the device main body 101 are coupled by a first hinge 202 to display the leg 201. The parts 102 are connected by the second hinge 203. The first hinge 202 can be rotated by a predetermined angle in the clockwise arrow A in the figure and in the opposite arrow B direction, and the second hinge 203 is also opposite to the clockwise arrow C in the figure. It can be rotated in the D direction.

  Although not clearly shown in the figure, a pair of leg portions 201 are provided in a direction parallel to the surface of the display portion 102.

  As is clear from FIG. 2, the angle of the display unit 102 with respect to the leg 201 is adjusted by the second hinge, and the position and angle of the display unit 102 with respect to the device main body 101 are further adjusted by the leg 201 and the first hinge. It is configured to be adjustable.

  That is, in the normal use state, the display unit 102 is positioned in a state where the display unit 102 is opened at a predetermined angle, for example, approximately 110 degrees, at the rearmost part with respect to the device main body 101 as shown in FIG.

  In the state of FIG. 1, the operation setting and function adjustment of the device main body 101 can be freely performed including the replacement of the optical disk. Operation setting and function adjustment in this state can be executed by both the operation unit 104 and a remote control signal from a remote controller (not shown).

  From the state of FIG. 1, it is possible to move the display unit 102 to the forefront of the device main body 101 while maintaining the angle. FIG. 3 is a diagram illustrating a state in which the display unit 102 is positioned at the forefront of the device main body 101. In the state shown in FIG. 3, the user cannot operate the operation unit 104 of the apparatus main body 101, and control such as operation setting and function adjustment is performed exclusively by the remote controller.

  In the process from the state of FIG. 1 to the state of FIG. 3, if the lower end of the frame portion 107 of the display unit 102 is in contact with the upper surface of the device main body 101, the surface of the device main body 101 may be damaged. Since a rim 106 on the surface of 101 is provided and a protrusion 108 is formed at the lower end of the frame 107 of the display unit 102, the end of the frame 107 of the display unit 102 contacts the upper surface of the device main body 101. If the angle is adjusted in this way, they are in contact with each other, and all the end portions of the frame portion 107 do not contact the surface of the device main body 101.

  Therefore, although the rim portion 106 is scratched, the rim portion 106 is formed to have a narrow width, and thus does not cause significant damage in appearance.

  In FIG. 1, the rim portion 106 has a considerable width so that it can be easily understood on the drawing. However, the rim portion 106 can have a very thin width and a cross-sectional shape, for example, a semicircular shape. The appearance will not deteriorate. Further, it is possible to achieve the above-described object by using only the rim portion 106 without forming the protrusion 108.

  Furthermore, in the electronic device 100 of the present invention, the first and second hinges can be rotated so that the surface of the device main body 101 and the surface of the display unit 102 are positioned substantially in a straight line. The electronic device 100 can also be used in a state where the device main body 101 is fixed to the wall surface.

  FIG. 4 is a diagram illustrating a state in which the electronic device 100 is fixed to the wall surface. That is, for example, a metal attachment member 401 is fixed to the back surface of the device main body 101, and the electronic device 100 is attached to the wall surface by fixing the attachment member 401 to the wall surface 402.

  Even in the state shown in FIG. 4, the angle and position of the display unit 102 can be adjusted. However, in the present invention, the first hinge 202 is configured to have a difference in rotational torque depending on the rotation direction. .

  That is, the operation of rotating the hinge in the direction of arrow A in order to position the display unit 102 upward can be rotated with a small torque so that it can be executed with a slight force. In order to maintain the above, in the reverse B direction, it is configured not to rotate unless a large torque is applied.

  Further, when the first hinge 202 is rotated in the direction of arrow A until the display unit 102 is in the position shown in FIG. 4, the first hinge 202 is provided with a lock mechanism so as to keep the position stable. ing.

  FIG. 5 is a diagram illustrating a specific configuration example of the first hinge 20. In FIG. 5, the shaft 501 is fixed at both ends by fixing members 502 and 503, and a rotating portion 504 formed integrally with the leg portion 201 is rotatably attached to the shaft 501. . A position regulating member 505 is fixed on the fixed member 502 side of the rotating portion 504, and a biasing force applying member 506 is slidably disposed on the shaft 501 on the fixed member 503 side.

  The biasing force imparting member 506 is formed so that the rotating portion 504 side has an inclined surface 507 that is inclined at a predetermined angle continuously over a circumference with respect to a direction orthogonal to the axis of the shaft 501. A protrusion 508 is integrally formed on the rotating portion 504 at a predetermined position on the surface facing the inclined surface 507.

  A compression coil spring member 509 is disposed between the biasing force application member 506 and the fixing member 503 so as to be wound around the shaft 501. The biasing force imparting member 506 is biased by the compression coil spring member 509 in the direction of the rotating portion 504 with a predetermined elastic force, so that the inclined surface 507 is always applied to the protrusion 508 of the rotating portion 504 with a predetermined elastic force. Come into contact.

  When the rotation unit 504 rotates, the projection 508 also rotates together, so that the position in contact with the inclined surface changes. Since the position of the shaft 501 in the axial direction of the shaft 501 is restricted by the position restricting member 505 on the fixing member 502 side of the rotating portion 504, when the rotating portion 504 rotates, the biasing force applying member 506 is moved in the axial direction of the shaft 501. It will slide.

  The movement of the biasing force applying member 506 toward the rotating portion 504 means releasing a part of the elastic force of the compression coil spring member 509, and the inclined surface 507 of the biasing force applying member 506 and the rotating portion 504. The contact force with the protrusion 508 is weakened, and the rotating portion 504 is rotated with a light torque force.

  On the contrary, the movement of the biasing force applying member 506 toward the fixing member 503 means that an elastic force is accumulated in the compression coil spring member 509, and the inclined surface 507 of the biasing force applying member 506 and the protrusion of the rotating portion 504 are stored. The contact force with 508 becomes strong, and the rotation unit 504 rotates by applying a strong torque.

  Regardless of the position where the projection 508 contacts the inclined surface 507, the rotational torque in the direction of releasing the elastic force of the compression coil spring member 509 is made substantially constant, and similarly, the rotational torque in the direction of accumulating the elastic force is made substantially constant. Is possible.

  As a result, in FIG. 2, the operation of rotating the first hinge 202 in the direction of arrow A can be performed with a light force, and the rotation of the first hinge 202 in the direction of arrow B is significant. Since torque is required, once the rotation angle of the first hinge 202 is determined, it can be held stably.

  Further, returning to FIG. 5, the biasing force applying member 506 is provided with a concave portion 510 at a predetermined position, and when the protrusion 508 of the rotating portion 504 is rotated to reach the position of the concave portion 510, It is configured to fit.

  As shown in FIG. 4, the position where the recess 510 is provided is a position where the first hinge 202 is rotated until the display unit 102 and the device main body 101 are in a substantially straight line. As a result, the display unit 102 is locked at the position shown in FIG. 4, and it is possible to prevent the display unit 102 from falling to the near side due to an impact.

  FIG. 6 shows a configuration example when the configuration shown in FIG. 5 is actually incorporated into the electronic device 100. A resin base 601 is provided, and fixing members 501 and 502 are fixed to the base 601. Further, a cover member 602 is disposed so as to cover the base 601. The rotating part 504 is configured integrally with the leg part 201.

  7 is a view of the rotating portion 504 and the biasing force applying member 506 shown in FIG. 5 as viewed from the axial direction of the shaft 501, and FIG. 7A shows the rotating portion 504 of the biasing force applying member 506. FIG. 7B is a view of the biasing force applying member 506 viewed from the rotating portion 504 side. For example, FIG. 7A shows a state in which the first hinge 202 is rotated in the direction of arrow B in FIG. 2, and from this state, the projection 508 is rotated until it is positioned in the recess 510 in FIG. 7B. It becomes possible.

  As described above, according to the present invention, the device main body 101 and the display unit 102 are connected by the first and second hinges 202 and 203 so that the angle and position of the display unit 102 with respect to the device main body 101 can be adjusted. In the constructed electronic device, the rim portion 106 is formed on the surface of the device main body 101, and the protrusion 108 is formed at the end of the frame portion 107 of the corresponding display portion 102. Even if it is used such that 107 moves while being in contact with the surface of the device main body 101, the protrusion 108 of the frame portion 107 and the rim portion 106 of the device main body 101 are in contact with each other, and the entire frame portion 107 is the Since there is no contact with the surface, an accident that damages the surface of the device main body 101 does not occur.

  Furthermore, when the first hinge 202 is rotated in a direction to open the angle of the display unit 102 with the device main body 101, the first hinge 202 can be executed with a small force, and when the first hinge 202 is rotated in the opposite direction, a large force is required. Thus, the display unit can be quickly and easily positioned at a target angle, and the position can be secured stably.

  Further, since the first hinge 202 is provided with a mechanism that locks the position of the first hinge when the display unit 102 is rotated to the position at which the display unit 102 is opened from the device main body 101 at the largest angle. Even in a state where 101 is used while being fixed to the wall surface, it is possible to prevent the occurrence of such a situation that the display unit 102 falls down.

  The present invention is not limited to the embodiment described above, and various modifications can be made without departing from the spirit of the present invention. For example, only the first hinge has a different torque according to the direction of rotation, but the second hinge 203 may have the same configuration.

  Furthermore, although a DVD player is taken as an example of the electronic device, it may be a television receiver or a personal computer.
