Description

  The present invention relates to a wall-mounted flat display mounting apparatus used for mounting a flat display such as a flat-screen television using a liquid crystal panel or a plasma display panel to a wall surface, and more particularly to a wall-mounted flat display mounting used for mounting to a corner portion. Relates to the device.

  In recent years, in the field of television equipment, demand for thin televisions using liquid crystal panels and plasma display panels has been rapidly increasing as screens have become larger. The biggest advantage of a flat-screen TV is that the depth is not increased and is reduced even in the case of a large screen.

  Such a flat-screen television is often used as a wall-mounted television by taking advantage of the advantages, and various attachment devices for attaching the flat-screen television to a wall have already been developed and marketed.

  By the way, conventional CRT televisions are often installed at corners because the rear part protrudes in a triangular shape. In the case of a flat display, it is often the case that the conventional CRT-type television is followed as it is and installed in the corner. For this reason, for example, Patent Document 1 also provides an attachment device for installing a flat display on a corner portion.

JP-A-11-018022

  When the flat display mounting apparatus described in Patent Document 1 is used, the flat display can be installed at the corner portion, but cannot be stored at a position along the wall surface. As a corner mounting device that can be stored, a single hinge mechanism is conceivable in which a flat display is mounted on one wall surface of the corner portion, and the flat display is rotated around a side end portion away from the corner. According to this mechanism, the flat display can be stored along the wall surface when not in use. Further, the flat display can be tilted by about 45 degrees with respect to the mounting wall surface during use.

  However, since the flat display turns around a fulcrum on the side away from the corner when tilting, the anti-hinge side moves away from the other wall surface of the corner portion as the tilt angle increases. As a result, in the state where it is inclined 45 degrees which is a normal use state, the side end portion on the hinge side of the flat display approaches the mounting wall surface, but the side end portion on the anti-hinge side is far away from the wall surface on the anti-mounting side, It becomes asymmetric. This is not only unnatural to the eye, but also reduces the space utilization efficiency of the corner.

  Another problem when installing a flat display on the corner of the room is that the mounting device can be stored along the wall, and the right side opens with the left side as a fulcrum and the left side opens with the right side as a fulcrum. It is necessary to prepare two types of left-opening types, which increases the number of models. In other words, when the flat display is mounted on the mounting device, it is convenient to hold the flat display from the point of operation. In the case of latching, the mounting device has a vertical direction. As a result, a right-opening type is required when attaching the latch-type attachment device to the left wall surface of the corner portion, and a left-opening type is required when attaching to the right wall surface.

  The present invention has been developed in view of such circumstances, and a first object of the present invention is that the flat display can be installed at an angle of approximately 45 degrees to the corner portion, and the flat display can be stored along the wall surface when not in use. In addition, it is an object of the present invention to provide a wall-mounted flat display mounting device for a corner that can be installed in a symmetrical state on the left and right sides in a symmetrical manner during use, and that can eliminate a gap from both sides of the flat display as much as possible.

  The second object of the present invention is that the flat display can be installed at an angle of approximately 45 degrees in the corner portion, and the flat display can be stored along the wall surface when not in use, and the flat display is latched. Another object of the present invention is to provide a wall-mounted flat display mounting device for a corner having no directivity that can be mounted on a wall surface on either side of the corner portion.

  In order to achieve the above object, a wall-mounted flat display mounting apparatus according to the present invention is a wall-mounted flat display mounting apparatus used for mounting a flat display to a wall surface. From the main arm, a holder for supporting the display, a main arm whose front end is rotatably connected to the center of the holder, and a base end is rotatably connected to one side of the base, A short tip is pivotally connected to the side of the holder, and a base end is pivotally connected to the other side of the base.

  In the wall-mounted flat display mounting device according to the present invention, the base is mounted on one of the corner portions so as to approach the corner. The long main arm that connects the center of the holder and one side of the base tilts approximately 45 degrees with respect to the base, allowing the flat display to have a uniform left and right gap at the corner and from both sides. It becomes possible to install in the state which was excluded automatically. When the main arm tilts toward the mounting wall, the flat display rotates to the opposite side by the action of the short sub-arm that connects the side of the holder and the side of the base on the tilted side. The arm also tilts in the same direction as the main arm. Then, when the main arm is along the base, the sub arm is along the base on the side, so that the holder is close to and parallel to the base, and the flat display is stored along the mounting wall surface.

  It is preferable that the main arm and the sub arm can be adjusted in length according to the size of the flat display to be attached. With this configuration, even if the size of the flat display to be attached changes, the gap on both sides can be suppressed as small as possible.

  The main arm and the sub arm also have an electrically driven forced turning mechanism, and the forced turning mechanism is preferably operated by a remote controller so that the tilt angle of the holder can be adjusted remotely. According to this configuration, a moving operation between the use position in the corner portion of the flat display and the storage position along the wall surface can be remotely performed by the remote controller.

  Preferably, the holder includes a main body and a latching portion, the main body has a slit hole, and the latching portion has a hook-shaped protrusion and a stopper hole. According to this configuration, since the hook-shaped protrusion of the latching portion engages with the slit hole of the main body, the latching portion can be attached to and detached from the main body and can be mounted upside down. With this attachment / detachment / reversing structure of the latching portion, it is possible to flip the mounting device upside down without changing the top / bottom of the latching portion. By reversing the device, it can be opened left or right, and can be attached to any wall surface of the corner.

  That is, in the case of right-opening in the initial state, it can be directly attached to the left wall surface across the corner, and the flat display can be latched. If the mounting device is turned upside down, it can be opened to the left and attached to the right wall surface across the corner. Even in the case of the left opening that is turned upside down, the flat display can be hooked by turning the hooking portion upside down and replacing it. Thus, it is possible to use upside down in spite of adopting the latching structure, and it is possible to attach the corner portion to any wall surface.

  A wall-mounted flat display mounting device according to the present invention includes a slanted long main arm that connects the center of the holder and one side of the base, and the side of the holder and the side of the base on the slant side of the main arm. In combination with a short sub-arm that connects the two, the flat display can be installed on a wall by tilting it approximately 45 degrees to the corner, and when not in use, the flat display can be stored along the wall. In addition, the flat display can be installed equally nicely at the time of use, and the space in the corner can be effectively used by eliminating gaps from both sides as much as possible.

  By attaching and detaching the latching part equipped to the holder to hang the display to the holder body and turning it upside down, it is possible to use it upside down even though it is a hanging type. As a result, it can be mounted on any wall surface that sandwiches the corner, and the cost can be reduced by reducing the number of models.

A vertical plate-like holder 50 is provided, and a main arm 60 and a sub arm 70 projecting horizontally from both sides of the base 40 to the front side to support the holder 50.

  The base 40 is made of a rectangular metal plate that is long horizontally, and has a plurality of screw holes 41 for fixing to a mounting wall surface 90A of the flat display. On the surface of one side portion of the base 40, first support portions 42 and 42 are provided in two upper and lower stages. On the surface of the other side part, second support parts 43, 43 are provided in two upper and lower stages. The support portions 42 and 43 on both sides are formed of a pair of upper and lower horizontal tongue-shaped cut pieces, and constitute a support bracket of vertical support shafts 44 and 45 that support the main arm 60 and the sub arm 70.

  The holder 50 includes a main body 51 made of a metal plate having substantially the same size and shape as the base 40, and a latching portion 52 that is detachably attached to both sides of the main body 51 in order to support a flat display on the front side of the main body 51. , 52. Each latching portion 52 has a plurality of hook-like projections 53 that protrude from both sides to the back side, and hooks the hook-like projections 53 to slit holes 54 provided in the main body 51. Thus, the front end of the side end portion of the main body 51 is held. Further, by hooking the hook-like projections 53... In other slit holes (not shown), each latching portion 52 can be attached to the front side of the side end portion with the main body 51 turned upside down. Here, in order to attach the latching portion 52 to the main body 51 so as to be detachable, a slit hole 54 and a hook-like projection 53 are provided on the latching portion 52 in the main body. However, the present embodiment is not particularly limited to this example as long as the purpose of detachably attaching it upside down can be achieved.

  On the front surface of each latching portion 52, retaining holes 55 and 55 for latching the flat display are provided in two upper and lower stages. Each retaining hole 55 has a composite shape in which a large-diameter insertion portion for latching the flat display and a fitting fixing portion obtained by linearly extending a lower portion of the insertion portion downward.

  On the back surface of the holder 50, two upper and lower bracket-shaped first support portions 56, 56 corresponding to the first support portions 42, 42 on one side are provided at the center in the width direction. In addition, two upper and lower bracket-like second support portions 57 and 57 corresponding to the second support portions 43 and 43 on the other side are located at the side end portions on the same side as the second support portions 43 and 43. Is provided.

  The main arm 60 is provided in two upper and lower stages, and both base end portions are rotatably connected by support shafts 44 perpendicular to the first support portions 42 and 42 of the base 40. Further, both end portions are rotatably connected by a support shaft 58 perpendicular to the first support portions 56, 56 of the holder 50. The length of the main arm 60 is set as follows.

  The base 40 is fixed close to the corner on one wall surface 90A of the corner portion. In this state, when the main arm 60 is inclined to about 45 degrees side with respect to the base 40 and the holder 50 is substantially perpendicular to the main arm 60, the flat display 80 supported by the holder 50 is cornered. The part is substantially symmetrically arranged with a slight uniform gap with respect to the wall surfaces 90A and 90B on both sides (use state). On the other hand, when the main arm 60 falls to the inclined side and becomes parallel between the base 40 and the holder 50, the flat display supported by the holder 50 becomes parallel to the mounting wall surface 90A and approaches the other wall surface ( Storage state). In order to realize these, the length of the main arm 60 is set according to the size of the flat display to be attached. Further, the length of the main arm 60 can be changed in a plurality of stages so as to cope with a change in the size of the flat display to be attached.

  Similarly to the main arm 60, the sub arm 70 is also provided in two upper and lower stages, and both base end portions are rotatably connected by the support shaft 45 perpendicular to the second support portions 43, 43 of the base 40. Further, both end portions are rotatably connected by a support shaft 59 perpendicular to the second support portions 57 and 57 of the holder 50. The length of the sub arm 70 is designed to be shorter than that of the main arm 60, and is specifically determined as follows.

  When the holder 50 and the flat display supported by the holder 50 are installed in the above-described use state, the sub arm 70 maintains this use state on the side away from the corner. Further, when the holder 50 and the flat display supported by the holder 50 are moved to the above-described retracted state, the sub arm 70 is parallel to the base 40 and the holder 50 on the extension line of the main arm 60. In order to realize these, the length of the sub arm 70 is set according to the arm mounting position, the length of the main arm 60, and the like. Further, similarly to the main arm 60, the length of the sub arm 70 can be changed in a plurality of stages so that the size of the flat display to be attached can be changed.

  Next, functions of the wall-mounted flat display mounting device according to the present embodiment will be described.

  The base 40 is fixed to one wall surface 90A of the corner portion where the flat display is to be installed. Specifically, the base 40 is fixed to the wall surface 90A near the corner so that the main arm 60 is located on the side close to the corner and the sub arm 70 is located on the side away from the corner. The flat display 80 is attached to the holder 50 supported by the base 40.

  The main arm 60 and the sub arm 70 are tilted away from the corner, and are placed along the mounting wall surface 90A. The holder 50 is parallel to the base 40, and the flat display 80 supported by the holder 50 is held at a storage position close to and parallel to the mounting wall surface 90A (FIGS. 3 and 4).

  From this storage position, the flat display is pulled out to the corner. At this time, the inclination angle of the main arm 60 is increased from approximately 0 degrees to approximately 45 degrees, and the flat display is pulled by the sub arm 70 that increases the inclination angle from 0 degrees, thereby restricting the operation. It turns to the sub arm side at the part and becomes substantially perpendicular to the main arm 60 (FIGS. 2 and 4).

  In this way, the flat display 80 is pulled out from the storage position parallel to the mounting wall surface 90A to the use position inclined by approximately 45 degrees with respect to both the wall surfaces 90A and 90B. At the use position, as described above, the flat display 80 is in a symmetrical state with a uniform distance from the wall surfaces 90A and 90B on both sides at the corner and with a small gap between the wall surfaces 90A and 90B.

  When attaching the flat display 80 to the other wall surface 90B of the corner portion, as shown in FIGS. 5A and 5B, the mounting device is turned upside down to fix the base 40 to the wall surface 90B. At the same time, the latching portions 52, 52 on both sides are removed from the main body 51 of the holder 50, and after the main body 51 of the holder 50 is inverted, the latching portions 52, 52 on both sides are mounted on the main body 51 again without being inverted upside down. To do. Accordingly, the portions other than the latching portions 52 and 52 on both sides are turned upside down, and the latching portions 52 and 52 on both sides are maintained in use.

  Although the base 40 and the main body 51 of the holder 50 and the arms 60 and 70 are turned upside down, the main arm 60 is positioned on the corner side and the sub arm 70 is cornered, although the base 40 is attached to the other wall surface 90B of the corner portion. Located on the side away from. As a result, the flat display can be stored in a state along the attachment wall surface 90B as in the case of attachment to the one wall surface 90A, and can be pulled out in a symmetrical use state at the corner portion. In other words, the latching portions 52, 52 on both sides are turned upside down so that they can be attached, so that it is not necessary to make a left opening type and a right opening type separately.

  In the above embodiment, the main arm 60 and the sub arm 70 are manually rotated, but this can also be performed electrically. By doing so, the reciprocating operation between the use position of the flat display and the storage position can be easily performed remotely by the remote controller. In this case, at least one of the main arm 60 and the sub arm 70 may be electrically operated, and it is not always necessary to electrically operate both.
