Description

  The present invention relates to an adapter holder and a display device including the adapter holder, and more particularly to an adapter holder that holds an AC / DC conversion adapter of a thin display device and a display device including the adapter holder.

  In a thin display device such as a liquid crystal television, an AC / DC conversion device may be provided outside the device as an AC / DC conversion adapter (hereinafter also simply referred to as “AC adapter”) in order to supply power to the device. is there. In particular, in the case of a small-sized liquid crystal television having a size of about 14 inches (inch), it is difficult to secure a space for installing an AC / DC conversion device inside the display device due to the progress of thinning of the display panel. In many cases, an AC adapter is used.

  By the way, when the AC adapter of the thin display device is provided outside, there are the following problems. That is, the AC adapter may be randomly placed between the outlet and the thin display device or in a rack where the thin display device is installed.

  There is a demand for improvement from the viewpoint of the appearance of the installation place and the arrangement of the wiring, with respect to the AC adapter being randomly placed in this way. For example, a technique for holding an AC adapter on a side surface of a housing of a display device is disclosed (see Patent Document 1). In the technique disclosed in Patent Document 1, when a notebook personal computer is used in an office, it is not displayed on the notebook personal computer but displayed on a display device such as a CRT (Cathode Ray Tube). A holding device for holding peripheral devices such as a notebook personal computer and an AC adapter is provided on the side of the display device.

  As can be seen mainly in FIG. 2, an element for holding is formed on the front side of the loading portion 40 at a portion below the approximate center. Further, a cross-shaped opening 54 (hereinafter also referred to as “cross-opening 54”) is formed on the front surface, which is a so-called back crack shape. In the cross opening 54 described above, the portion extending in the lateral direction is formed continuously over substantially the center of both side surfaces. Further, as shown in FIGS. 7A and 7C, the vertically extending portion is continuously formed over substantially the center of the bottom surface. A portion where the cross opening 54 is formed to extend to the bottom surface of the loading unit 40 is referred to as a bottom surface opening 52.

  In other words, by forming the cross opening 54 described above, the left central rib 41a and the right central rib 41b are formed in an L shape with a desired width from the center of the side surface of the loading unit 40. Similarly, a left lower rib 42a and a right lower rib 42b are formed in an L shape with a desired width from the lower side of the side surface of the loading portion 40. Hereinafter, when the left central rib 41a and the right central rib 41b are not distinguished from each other, they are simply referred to as “center rib 41”, and when the left lower rib 42a and the right lower rib 42b are not distinguished from each other, they are simply referred to as “lower rib 42”. By adopting the shape as described above, the loading unit 40 holds the AC adapter 15 so as to hold it. Moreover, the center rib 41 and the lower rib 42 are provided with a spring property by the above materials and configurations.

  Further, on the side surface of the loading unit 40, a lower left side opening 47a and a lower right side opening 47b are formed continuously from the lower end portion on the rear side to the rear surface and the bottom surface. Hereinafter, when the lower left side opening 47a and the lower right side opening 47b are not distinguished, they are simply referred to as “side openings 47”. Further, as shown in FIGS. 4 and 7, a back center opening 48 is formed at the center of the back side surface of the loading unit 40. In this way, the cross opening 54, the side opening 47, and the back center opening 48 are formed, so that the heat generated by the AC adapter 15 can be appropriately transmitted from the cross opening 54, the side opening 47, and the back center opening 48 to the outside. Can be released.

  Furthermore, as shown in FIGS. 3 (c), 4 (b), 7 (a), etc., the left center rib interference piece 55a and the right center rib are respectively provided on the back surfaces of the left center rib 41a and the right center rib 41b. A rib interference piece 55b is projected, and similarly, a left lower rib interference piece 56a and a right lower rib interference piece 56b are projected on the back surfaces of the left lower rib 42a and the right lower rib 42b, respectively. Hereinafter, when the left central rib interference piece 55a and the right central rib interference piece 55b are not distinguished from each other, they are simply referred to as “center rib interference piece 55”, and when the left lower rib interference piece 56a and the right lower rib interference piece 56b are not distinguished from each other, they are simply referred to as “center rib interference piece 55b”. This is referred to as “lower rib interference piece 56”. The shapes of the central rib interference piece 55 and the lower rib interference piece 56 are triangular in cross section.

  Further, a back rib 53 is formed vertically in the lower center inside the back surface of the loading unit 40. Here, there is only one back rib 53, but the present invention is not limited to this.

  Further, the attachment portion 45 has a substantially inverted trapezoidal shape, is formed in a concave shape on the back side from the loading portion 40, and fits into the hollow 37 of the handle 14. In addition, as shown in FIG. 4, the concave depth is substantially the same as the height h2 (see FIG. 8) of the extending portion 32. Further, the attachment left side surface portion 51a and the attachment right side surface portion 51b are formed in a shape that is in close contact with the left side portion 33a and the right side portion 33b of the handle 14. When the left side surface portion 51a and the right side surface portion 51b are not distinguished from each other, they are simply referred to as “mounting side surface portions 51”.

  In addition, a left locking piece 43a and a right locking piece 43b extending in the lateral lateral direction are formed as plate-shaped pieces on the mounting left side surface portion 51a and the mounting right side surface portion 51b, respectively. As shown in FIG. 5 and the like, the left locking piece 43a and the right locking piece 43b are formed with a circular left protruding piece 44a and a right protruding piece 44b slightly protruding with a thickness h1 on the back side. The handle 14 is fitted into the left center fixing hole 35a and the right center fixing hole 35b.

  In addition, when fitting the attachment portion 45 to the hollow portion 37 of the handle 14, the inverted trapezoidal shape of the attachment portion 45 and the hollow portion 37 is used. First, the attachment portion 45 is inserted from slightly above the final fitting state of the hollow 37, and the attachment portion 45 is further moved downward. Then, the attachment side surface portion 51 is in close contact with the side portion 33 of the handle 14. At this time, the left protruding piece 44a and the right protruding piece 44b are fitted in the left center fixing hole 35a and the right center fixing hole 35b.

  As a result, the adapter holder 11 is temporarily fixed to the handle 14. Thus, the fitting position of the adapter holder 11 can be easily adjusted by using the inverted trapezoidal hollow 37 of the handle 14. Subsequently, a screw is passed through a fixing hole 46 provided at the lower center of the mounting portion 45, and a screw is screwed into a screw hole (not shown) provided in the display unit main body 12. As a result, the adapter holder 11 is completely fixed to the display unit main body 12.

  Next, the insertion of the AC adapter 15 into the loading unit 40 will be described mainly with reference to FIGS.

  First, as shown in FIG. 8A, the AC adapter 15 is inclined so that the upper side is facing forward, and the lower part of the AC adapter 15 is inserted into the upper surface opening of the loading unit 40 in the direction of arrow P. At this time, the convex portion 72 of the AC adapter 15 and the central rib interference piece 55 are formed with dimensions and positions that do not interfere with each other. Even if the position where the AC adapter 15 is inserted is slightly shifted and the convex portion 72 and the central rib interference piece 55 interfere with each other, since the central rib 41 has a spring property, The central rib 41 moves outward, and the AC adapter 15 is smoothly inserted.

  Next, as shown in FIG. 8 (b), the AC adapter 15 is rotated in the direction of the arrow Q so as to be vertical. When the AC adapter 15 becomes vertical, the AC adapter 15 is further moved slightly forward (to the left side of the figure). ). In this state, there is a space with a slight width W between the inner surface on the back side of the loading unit 40 and the AC adapter 15, and it can move back and forth (left and right in the figure).

  Then, as shown in FIG. 8C, the AC adapter 15 is moved downward, which is the direction of the arrow R, and the AC adapter 15 is inserted to the back of the loading unit 40. At this time, the back rib 53 is formed with the same width W as the above space, and when the AC adapter 15 is completely inserted into the loading portion 40, the back rib 53 and the lower rib interference piece 56 cause the AC adapter. 15 is fixed and wobble is prevented. In addition, since the fixing by the back rib 53 and the lower rib interference piece 56 is performed at a part of the lower side of the AC adapter 15, it can be easily taken out when an operation of taking out the AC adapter 15 is performed.

  As shown mainly in FIG. 4B, the central rib interference piece 55 and the lower rib interference piece 56 interfere with the convex portion 72 formed on the AC adapter 15, and the AC adapter 15 is placed on the loading portion 40. When inserting or removing, the vertical movement is restricted, and the AC adapter 15 is prevented from being easily removed from the loading unit 40 unintentionally. Therefore, even if the display device 10 falls, the AC adapter 15 cannot be removed from the adapter holder 11.

  4 (b) and 8 (c), the lower rib interference piece 56 is in a state of being locked to the convex portion 72 of the AC adapter 15. For example, this locking is released and the AC adapter 15 is loaded. Even in the case of moving in the direction of exiting from the portion 40 (upward in the drawing), the central rib interference piece 55 provided in the vicinity of the entrance / exit of the loading portion 40 interferes, and no force is applied with the intention of being removed by a person. As long as it cannot be extracted easily.

  Further, when the AC adapter 15 is held by the loading unit 40, the adapter cable 16 is inserted through the bottom opening 52. As described above, since the bottom opening 52 and the front cross opening 54 are formed continuously, the adapter cable 16 is separated from the AC adapter 15 when the AC adapter 15 is held by the adapter holder 11. There is no need.

  As described above, according to the present embodiment, in the thin display device 10 having the handle 14 on the back surface, the adapter holder 11 is fitted and attached to the handle 14, so that the main body of the AC adapter 15 and the adapter cables 16 and 17 are attached. Can be organized effectively. Further, ribs (41, 42) are provided on the front side of the adapter holder 11 so as to form an opening (54), and the AC adapter 15 is held by the ribs (41, 42). By providing the openings (54, 47, 48) on the front surface, the side surface, and the back surface, the heat of the AC adapter 15 can be appropriately released to the outside. Furthermore, by forming the convex shape (55, 56) that interferes with the AC adapter 15 on the back surface of the rib (41, 42), for example, even when the display device 10 falls down, it is loaded. The AC adapter 15 is not easily removed. Moreover, since said rib (41, 42) has spring property, when inserting or taking out AC adapter 15, it can implement | achieve with appropriate force.

  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 the combination of the respective components, and such modifications are within the scope of the present invention.

  For example, in the embodiment, the central rib interference piece 55 and the lower rib interference piece 56 provided on the inner surfaces of the central rib 41 and the lower rib 42 are provided on the AC adapter 15 in order to limit the vertical movement of the AC adapter 15. Although it interferes so that it may latch on the provided convex part 72, it is not the meaning limited to this. In addition, for example, the central rib interference piece 55 and the lower rib interference piece 56 may be locked in a predetermined groove provided in the AC adapter 15.
