Description

  The present invention relates to a display device such as a liquid crystal display device or a plasma display device.

  A display device such as a television includes a display unit having an image display surface on the front side and a stand that supports the display unit in an upright state. In such a display device in which the stand supports the display unit in an upright state, an overturn prevention tool for preventing overturning due to an earthquake is attached as an accessory at the time of packaging. This overturn prevention tool includes a pair of clamps to which both ends of a string body are locked, two small screws for attaching the clamps to the display unit, a band body having a parallel through-hole, and the band body on a stand. A small screw that is attached to the bottom surface, and is configured such that a clamp or a band body can be selected in accordance with a place where the display device is disposed. For example, when the display device is arranged in the vicinity of the wall surface, both ends of the string body are fixed to the display unit by clamps, and a commercially available hook screw to be locked in the middle of the string body is screwed into the wall surface. When the display device is mounted on the mounting table, the band body is fixed to the stand with a small screw and the other side of the band body is fixed to the mounting table with a commercially available small screw. To prevent falling.

Further, as a display device configured to prevent a fall due to an earthquake, an auxiliary foot pivotally supported by a horizontal axis to be pivoted up and down on a housing of a display unit having a housing, and a cavity for storing the auxiliary foot A display device configured to prevent the display device from falling by pulling out the auxiliary foot from the cavity and bringing the tip of the auxiliary foot into contact with the floor surface is known (for example, see Patent Document 1). ).
Japanese Utility Model Publication No. 2-126478

  However, in the case of a display device to which a fall prevention tool such as a clamp and a band body is attached as an accessory, the attachment of the fall prevention tool may be forgotten at the time of entire packaging, and when using a clamp It is necessary for the user to easily separate the string body and the hook screw, and when using the band body, the band body needs to be fixed to the bottom of the stand with the display unit turned over. In the case of a large size, one worker cannot cope with it, and it is necessary to cause the display device to fall / stand up by a plurality of workers, and an improvement measure has been demanded.

  Further, in Patent Document 1, since the auxiliary foot is rotated up and down and the rotation path of the auxiliary foot becomes relatively wide, other articles cannot be placed near the display device, and a relatively wide space is required. In addition, there is a problem that the appearance becomes unsightly because a cavity whose longitudinal direction is up and down is provided in the display portion, and the cavity is relatively large and opened to the outside.

  The present invention has been made in view of such circumstances, and a main object thereof is a stand that supports the display unit in a standing state, a cavity that is open to the outside, an attachment portion that is disposed in the cavity, and a cavity. By installing a fall prevention body attached to the attachment part so that it can be inserted and removed in the lateral direction, even a relatively large display device can be easily prevented from falling. And it is providing the display apparatus which can be arrange | positioned in a comparatively narrow space and can make the open edge of a cavity comparatively small.

  Another purpose is that the fall prevention body has a long hole into which the attachment portion is inserted and a knob that faces the open edge of the cavity, and the fall prevention body can be moved to the attachment portion. Accordingly, an object of the present invention is to provide a display device that can easily pull out the fall prevention body to the outside and can easily attach the fall prevention body to a mounting table or the like.

  Another purpose is that the fall prevention body has a knob that faces the open edge of the cavity, and the fall prevention body can be easily pulled out by attaching the fall prevention body to the attachment portion so as to be rotatable. Another object of the present invention is to provide a display device that can easily attach a fall prevention body to a mounting table or the like.

  A display device according to the present invention includes a display unit having an image display surface on the front side, and a stand that supports the display unit in an upright state, wherein the stand includes a cavity opened to the outside, An attachment portion disposed in the cavity, and a fall prevention body attached to the attachment portion in the cavity so as to be capable of lateral insertion and removal and preventing the display portion from overturning. Features.

  In this invention, since the fall prevention body is attached to the cavity of the stand, it is possible to eliminate forgetting to attach it at the time of packing, and the fall prevention body in the cavity is pulled down in the horizontal direction. Therefore, even a relatively large display device can be easily prevented from falling, and the anti-falling body can be pulled out horizontally, so that it is relatively narrow. Can be placed in space. Further, since the fall prevention body can be inserted and removed in the horizontal direction, the open edge of the cavity can be made relatively small, and the appearance of the display unit can be simplified.

  Further, in the display device according to the present invention, the fall prevention body has a long hole into which the attachment portion is inserted, and a knob portion that faces the open edge of the cavity, and moves to the attachment portion. It is possible to attach it.

  According to the present invention, since the fall prevention body can be easily pulled out to the outside by moving the inside of the cavity by picking the knob facing the open edge of the cavity, the fall prevention body can be easily attached to the mounting table or the like. I can wear it.

  Further, the display device according to the present invention is characterized in that the fall prevention body has a knob portion facing the open edge of the cavity, and is attached to the attachment portion so as to be rotatable.

  According to the present invention, the fall prevention body can be easily pulled out to the outside while rotating the inside of the cavity by picking the knob that faces the open edge of the cavity. I can wear it.

  As described in detail above, according to the present invention, even a relatively large display device can be easily prevented from falling, and can be arranged in a relatively small space. Further, the open edge of the cavity can be made relatively small, and the appearance of the display unit can be simplified.

  In addition, according to the present invention, the fall prevention body can be easily pulled out by picking the knob that faces the open edge of the cavity, and the fall prevention body can be easily attached to the mounting table or the like.

Hereinafter, the present invention will be described in detail with reference to the drawings illustrating embodiments thereof.
