CROSS-REFERENCE TO RELATED APPLICATIONS  
       [0001]     This application claims the benefit of Korean Patent Application No. 2005-0019353, filed on Mar. 8, 2005, in the Korean Intellectual Property Office, the context of which is herein incorporated by reference in its entirety.  
       BACKGROUND OF THE INVENTION  
       [0002]     1. Field of the Invention  
         [0003]     The present invention relates to a wall mount for a display apparatus, and more particularly, to an improved wall mount having a tilting structure to tilt the display apparatus to a desired viewing angle.  
         [0004]     2. Description of the Related Art  
         [0005]     In today&#39;s consumer electronics market, many kinds of display apparatuses are used to visually display alphanumeric and/or pictorial images for viewing by a user. Recently, flat panel displays, such as plasma display panels (PDPs) or a liquid crystal displays (LCDs) have become widely used as televisions or computer monitors, and research and development of flat panel displays continues. The consumer demand for flat panel displays is increasing the demand for wall mount apparatuses (wall mounts) that occupy a small amount of space and can be installed in more places throughout home and business environments.  
         [0006]     In a conventional wall mount, an angle adjusting member mounted between a supporting bracket and a rotating bracket is used to adjust the angle at which the display apparatus is tilted relative to a wall or other reference point. Illustrative examples of conventional wall mounts are provided by at least Korean Utility Model Application No. 20-1998-23535, Korean Patent Application No. 10-2003-5107, Korean Utility Model Application No. 20-2003-23146, and Japanese Patent First Publication No. 1998-174021, etc.  
         [0007]     The assemblies comprising conventional wall mounts, however, tend to be complicated, and adjusting the tilt angle of the display apparatus can be difficult. Moreover, many angle adjusting members of conventional wall mounts are time-consuming and expensive to manufacture due to their large numbers of component parts.  
       SUMMARY OF THE INVENTION  
       [0008]     An improved wall mount apparatus (wall mount) for supporting a display apparatus in an easily tiltable viewing position, and a simplified structural assembly for the wall mount&#39;s tilting mechanism are disclosed.  
         [0009]     The improved wall mount may include a base to be attached to a wall, may further include a supporting bracket supported by the base, and may further include a rotating bracket tiltably coupled to the supporting bracket. A flat panel display apparatus may be mounted to the rotating bracket. An elastic member may be coupled with the supporting bracket. A supporting wire may be coupled with the electric member and the rotating member to expand or contract the elastic member as the rotating bracket moves between a first position adjacent the supporting bracket to a second position away from the supporting bracket.  
         [0010]     An apparatus provided by the invention may include a supporting bracket having a length greater than its width, wherein the supporting bracket includes a first top surface substantially orthogonally coupled with a first sidewall and a second sidewall to define a channel. The supporting bracket may further include a flange substantially orthogonally coupled with at least the first sidewall or the second sidewall. Additionally, the first top surface may include a wire slot formed therein. The apparatus may further include a rotating bracket having a length greater than its width and rotatably coupled with the supporting bracket. The rotating bracket may include a second top surface substantially orthogonally coupled with a third sidewall and a fourth sidewall to define a second channel. The rotating bracket may further include a wire coupling part formed within the second channel, and the second channel may have a greater width than that of the first channel. The apparatus may further include a friction member having a first end movably coupled with the supporting bracket and a second end movably coupled with the rotating bracket. An elastic member, to counterbalance movement of the rotating member away from the supporting bracket and to assist movement of the rotating member toward the supporting bracket, may be positioned within the first channel. Additionally, a wire supporter may be positioned within the first channel away from the elastic member and proximate the wire slot. A supporting wire may have a first end coupled with the wire coupling part and a second end coupled with the elastic part, and a portion of the supporting wire may pass through the wire slot and about a portion of the wire supporter.  
         [0011]     Various features of the invention are set forth in the following description. Additional may be apparent from accompanying drawings or may be learned by practicing the invention.

     DETAILED DESCRIPTION OF THE INVENTION  
       [0017]     Descriptions of one or more embodiments of the invention are set forth below. Examples of these embodiments may be illustrated in the accompanying drawings, wherein like reference numerals may refer to like elements throughout. In describing the invention, reference is made to the accompanying drawings.  
         [0018]     Referring to  FIGS. 1, 2 , and  3 , an improved wall mount apparatus (wall mount) for supporting a display apparatus may include a base  20 , a supporting bracket  30 , a rotating bracket  40 , an elastic member  50 , and a supporting wire  60 . The base  20  may have a uni-body or multi-component construction, and may be formed of a rigid material, including, but not limited to metal, a polymeric compound, plastic, etc. The base  20  may have a length greater than its width, and its two side surfaces may be longer than its two ends. More particularly, the base  20  may include a substantially flat center panel  21  longitudinally disposed about the base&#39;s longitudinal central axis. Recessed flanges  22 A and  22 B may extend laterally on either side of the center panel  21 . Each flange may include one or more openings  23  to reduce weight and/or to facilitate fastening the base  20  to a support surface. The outer edge of flange  22 A may include a raised lip  24 A, and the outer edge of the flange  22 B may include a raised lip  24 B. Each of the raised lips  24 A and  24 B may extend substantially vertically upwards from its parent flange  22 A or  22 B. The top edge of each flange  22 A and  22 B may be approximately level with a top surface of the center panel  21 , which may be raised a predetermined distance above a top surface of each flange  22 A and  22 B. In such a configuration, the space between one side of the center panel  21  and the raised lip  24 A forms a first channel, and the space between the other side of the center panel  21  and the other raised lip  24 B forms a second channel. As explained in further detail below, the base  20  functions at least to support the supporting bracket(s)  30  and or the rotating bracket(s)  40 . Of course, the embodiment described above and illustrated in  FIG. 1  is merely exemplary, and the invention may also include a base  20  having other geometric shapes and/or structures.  
         [0019]     Referring to  FIGS. 1 and 2 , the invention further includes at least one, but preferably two, supporting bracket(s)  30 . Each supporting bracket  30  has a length longer than its width, and its two sides are longer than its ends. Additionally, each supporting bracket  30  includes a substantially planar top surface  30 A, sidewalls  30 B and  30 C, cutouts  39 A and  39 B, and flanges  31 A,  31 B,  31 C, and  31 D.  
         [0020]     The planar top surface  30 A is longitudinally disposed along the supporting bracket&#39;s longitudinal center axis. A first U-shaped cutout  39 A is formed in a top end of the top surface  30 A, and a second U-shaped cutout  39 B is formed in a bottom end of the planar top surface  30 A. The base of cutout  39 A forms a first gap in the top end of the top surface  30 A, and the cutout&#39;s opposite end may be square or radiused. Similarly, the base of cutout  39 B forms a second gap in the bottom end of the top surface  30 A, and the cutout&#39;s opposite end may be square or radiused. Additionally, the top surface  30 A includes a wire slot  32  formed a predetermined distance below the square or radiused end of cutout  39 A. The wire slot  32  substantially traverses the width of the top surface  30 A, and has a width slightly larger than a diameter of a supporting wire  60 . The interior edges of the slot  32  may be blunted or covered with an anti-chafing material.  
         [0021]     Opposing sidewalls  30 B and  30 C extend substantially orthogonally below a horizontal plane passing through the top surface  30 A, and may be seamlessly attached to the top surface  30 A along an entire length thereof.  
         [0022]     At a predetermined distance proximate the square or radiused end of the cutout  39 B, a first P-shaped or L-shaped supporting hole  34  may be formed in each of the opposing sidewalls  30 B and  30 C. The long portion of the supporting hole  34  may terminate at one end in a gap formed in an edge of its parent sidewall  30 B or  30 C, and terminate at the other end in a substantially orthogonal short portion that extends toward the bottom end of the bracket  30 .  
         [0023]     At a predetermined distance between the square or radiused end of the cutout  39 A and the wire slot  32 , a second P-shaped or L-shaped supporting hole  36  may be formed in each of the opposing sidewalls  30 B and  30 C. The long portion of the supporting hole  36  may terminate at one end in a gap formed in an edge of its parent sidewall  30 B or  30 C, and terminate at the other end in a substantially orthogonal short portion that extends toward the bottom end of the bracket  30 .  
         [0024]     At a predetermined distance proximate the short portion of the second cutout  36 , a third P-shaped or L-shaped supporting hole  38  may be formed in each of the opposing sidewalls  30 B and  30 C. The long portion of the supporting hole  38  may terminate at one end in a gap formed in an edge of its parent sidewall  30 B or  30 C, and may terminate at the other end in a substantially orthogonal short portion that extends toward the top end of the bracket  30 .  
         [0025]     Flanges  31 A and  31 B may extend downward a predetermined distance from the top end of the bracket  30 , and extend substantially orthogonally outward from each of their parent sidewalls  30 B and  30 C. Each flange  31 A and  31 B may include one or more openings  35 A through which a fastening means, including, but not limited to, a bolt, may be inserted. Additionally, the bottom edge of each flange  31 A and  31 B may include a clip (i.e. fastener)  37 . The clip(s)  37  may be L-shaped. The long portion of the clip may extend substantially orthogonally upwards from a top surface of its parent flange  31 A or  31 B. As illustrated in  FIG. 1 , the clips  37  may engage the raised lip  24 A of the base  20 . Of course, clips  37  having other geometric shapes and/or structures may also be used.  
         [0026]     Flanges  31 C and  31 D extend substantially orthogonally outward from each of their parent sidewalls  30 B and  30 C. Each flange  31 C and  31 D may be each positioned between the first supporting hole  34  and the bottom end of the bracket  30 . Each flange  31 C and  31 D may include one or more openings  35 B through which a fastening means, including, but not limited to, a bolt, may be inserted. As shown in  FIG. 1 , the flanges  31 C and  31 D may be positioned a predetermined distance below the raised lip  24 B of the base  20 . In other embodiments, the flanges  31 C and  31 D may be connected with (one or more) base(s)  20 .  
         [0027]     Each supporting bracket  30  may further include first hinge member(s)  82  and second hinge member(s)  91 . Each first hinge member  81  and each second hinge member are connected with their respective parent sidewalls  30 C and  30 D. More specifically, each first hinge member  82  is positioned on sidewall  30 B or  30 C proximate the bottom end of the bracket  30 . Each second hinge member  91  is positioned on each sidewall  30 B or  30 C between each first supporting hole  34  and each first hinge member  81 . The first hinge member(s) rotatably connect the bottom end(s) of bracket(s)  30  to the bottom end(s) of the rotating bracket(s)  40 . The second hinge member(s)  91  rotatably and/or slidably connect to first end(s) of friction member(s)  90  that further link the supporting bracket(s)  30  with rotatable bracket(s)  40 . Referring briefly to  FIG. 4 , each second hinge member  91  may slidably fit within a slot  93  formed in the corresponding sidewall  30 B or  30 C. Referring again to  FIGS. 1 and 2 , the other end(s) of the friction member(s)  90  may rotatably connect with third hinge member(s)  92  that rotatably connect with the sidewalls  40 B and  40 C of the rotating bracket(s)  40 .  
         [0028]     The friction member  90  may be a mechanical linkage that supplies a friction force to control the tilt angle during rotation of the rotating bracket  40  (further discussed below) so that the rotating bracket  40  is maintained in a desired tilted state although a sustained gravitational force is applied after the rotating bracket  40  occupies the desired tilt angle. Of course, other types and/or positions of friction members  90  may be used, depending on the amount of frictional force required to counteract the weight of individual masses of different flat panel displays.  
         [0029]     The following paragraphs reference the supporting holes  34 ,  36 , and  38 , discussed above, that are formed in each of the supporting bracket(s)  30 . Referring to  FIGS. 1 and 2 , the first supporting hole  34  supports a shaft  52  of an elastic member  50 . Additionally, the second supporting hole  36  supports a shaft of a first grooved, cylindrical wire supporter  70 . Similarly, the third supporting hole  38  supports a shaft of a second (auxiliary) grooved, cylindrical wire supporter  72 .  
         [0030]     Each of the wire supporters  70  and  72  may be formed of a rigid material including, but not limited to, metal, plastic, a polymeric compound, etc. The first wire supporter  70  includes spaced-apart, circumferential grooves  71  to receive a supporting wire  60  therein. Similarly, the second (auxiliary) wire supporter  72  includes spaced-apart, circumferential grooves  72  to receive a supporting wire therein. The first and second wire supporters  70  and  72  rotate as the supporting wire(s)  60  move against them when the rotating bracket(s)  40  are tilted to a desired viewing position. The wire supporters  70  and  72  may be provided to prevent the supporting wire(s)  60  from chafing (and/or fraying) against the edges of the wire slot  32 .  
         [0031]     Referring briefly to  FIG. 4A , the supporting wires  60  may pass over top of and around the right side of the first wire supporter  70 , and then around the left side of the second wire supporter  72  before angling downward to connect with a spring  56 . Thus, the wire supporters  70  and  72  each support a separate part of the supporting wires  60  and thereby maintain a predetermined tension state of the supporting wires  60 . The supporting wire(s)  60  should be made of a strong material that may include, but is not limited to, piano wire.  
         [0032]     Referring briefly to  FIG. 3 , the wires  60  may be mounted in parallel to the spring  56  wound about a roller  54  connected to a cylindrical shaft  52 . As mentioned above, the shaft  52  may be positioned within the first supporting holes  34  formed in the supporting bracket  30 .  
         [0033]     The spring  56  and the shaft  52  may be components of the elastic member  50 . The spring  56  may be a leaf spring shaped like a plate. Because flat panel displays of different masses will require different amounts of counterbalancing force, the spring&#39;s tensile strength may be adjusted as desired by using different materials and/or by varying the spring&#39;s width/thickness. Particular values of spring constants and/or tensile strengths are not listed here because they will vary depending on at least the weight of each particular flat panel display apparatus  80  (and/or other factors such as the friction provide by the friction member  90 ). Moreover, such values should prove easy for a skilled artisan to calculate or otherwise determine without undue experimentation.  
         [0034]     Referring again to  FIGS. 1 and 2 , the invention further includes a number of rotating brackets  40  that equals the number of supporting brackets  30 . Each rotating bracket  40  has a length greater than its width, and its two sides are longer than its ends. Additionally, each rotating bracket  40  includes a substantially planar top surface  40 A, sidewalls  40 B and  40 C, mounting apertures  42 A and  42 B, and a coupling part  44 . Each bracket  40  is made of a rigid material, including, but not limited to, metal, plastic, a polymeric compound, etc.  
         [0035]     The top surface  40 A is longitudinally positioned along the bracket&#39;s longitudinal center axis. A first mounting aperture  42 A may be formed in the top surface  40 A at a top end thereof, and a second mounting aperture  42 B may be formed in the top surface  40 A at a bottom end thereof. Each mounting aperture  42 A and  42 B may have a top portion that is wider than a bottom portion. Additionally, each mounting aperture may function to receive and/or secure a fastening means connected with a display apparatus. The fastening means may include, but is not limited to a pin, bolt, tab, clip, etc. In particular, the wide top portion of each aperture may first receive the fastening means, which then moves downward to slidably engage the aperture&#39;s narrow bottom portion.  
         [0036]     Opposing sidewalls  40 B and  40 C, one per side of the top surface  40 A, extend substantially orthogonally below a horizontal plane paralleling the top surface. Each sidewall  40 B and  40 C may seamlessly connect with the top surface  40 A along an entire length thereof.  
         [0037]     As mentioned above, the bottom end of each rotating bracket  40  includes the first hinge member  82 , as well as the third hinge member  92 , which is positioned a predetermined distance above the first hinge member  82 . One end of a mechanical link (friction member  90 ) may movably connect with third hinge member  92 , and the other end of the friction member  90  may movably connect with the second hinge member  91 .  
         [0038]     A U-shaped recess  45  may be formed in each of the sidewalls  40 B and  40 C. A bottom portion of each recess  45  may include a gap formed in the edge of the recess&#39; parent sidewall  40 B or  40 C. A top portion of each recess  45  may be radiused. Each recess  45  is sized and positioned to fit over and/or about the second hinge member  91  that is slidably connected with the lower portion of each supporting bracket  30 . Use of recesses  45  enables the rotating bracket  40  to occupy a first closed position, in which the top surface  40 A of the rotating bracket  40  substantially parallels the top surface  30 A of the supporting bracket  30 , and the sidewalls  40 B and  40 C of the rotating bracket  40  overlap (and/or substantially parallel) the sidewalls  30 B and  30 C of the supporting bracket  30 .  
         [0039]     Additionally, a coupling part  44  may be fixedly connected with the underside of top portion of the rotating bracket  40 . More particularly, the coupling part  44  may be fixedly positioned within the channel  40 D, which is defined as the area bounded by sidewalls  40 B and  40 C and the top surface  40 A. Additionally, the coupling part  44  may be positioned on the underside of the top surface  40 A at a predetermined distance below the bottom portion of the first aperture  42 A. Referring to  FIG. 1 , the coupling part  44  may further be positioned such that it fits within the wire slot  32  formed on the supporting bracket  30  when the rotating bracket  40  occupies its first closed position ( FIG. 4A ). The wires  60  are coupled at their first ends to the coupling part  44 , and at their second ends to the spring  56 . Additionally, an upper portion of the wires  60  passes through the wire slot  32  as the rotating bracket  40  is moved from its first closed position to a second open position ( FIG. 4B ) and back again.  
         [0040]      FIGS. 4A and 4B  illustrate side views of the wall mount of  FIGS. 1, 2 , and  3 . More particularly,  FIG. 4A  depicts the wall mount in a first closed position, while  FIG. 4B  depicts the wall mount in a second open position (i.e., tilted to a desired viewing angle relative to the vertical).  FIGS. 4A and 4B  each show the flat panel display apparatus  80  coupled to rotating brackets  40 . Each figure further includes a cut-away view of the supporting bracket(s)  30 . Specifically, the sidewall  30 C that was shown in  FIGS. 1 and 2  has been removed to illustrate the positioning of first wire supporter  70 , second wire supporter  72 , elastic member  50 , friction member  90  and slot  92 . Additionally, the base  20  and flanges  31 B and  31 D have been omitted so as not to complicate the depiction of the invention unnecessarily.  
         [0041]     From both  FIGS. 4A and 4B , it can be seen that the first wire supporter  70 , second wire supporter  72 , and the elastic member  50  may be positioned within a channel defined by sidewall  30 B, sidewall  30 C, and top surface  30 A of each supporting bracket  30 .  
         [0042]     Comparing  FIGS. 4A and 4B , it is seen that the position of hinge member  91  may traverse a length of the slot  93  as the rotating bracket(s)  40  (and removably attached flat panel display) are rotated between the first closed position ( FIG. 4A ) to the second open position ( FIG. 4B ).  
         [0043]     Exemplary methods of manufacturing, assembling, installing, and operating a wall mount manufactured in accordance with the principles of the invention are now described with reference to  FIGS. 1, 2 ,  3 ,  4 A, and  4 B. The steps described may be performed in any suitable order, and the invention is not limited merely to the order of steps described below.  
         [0044]     As mentioned above, the base  20 , the bracket assemblies  30 / 40  and their component parts are manufactured of a rigid material, such as, but not limited to metal, using known manufacturing techniques, that may include, but are not limited to, die-stamping, welding, molding, etc. In particular, at least the base  20 , supporting bracket(s)  30 , and the rotating bracket(s)  40 , first wire supporter  70 , second wire supporter  72 , supporting wires  60 , elastic member  50 , friction member(s)  90 , and hinge members  82 ,  91 , and  92  may be manufactured separately as independent components and then assembled.  
         [0045]     For example, the bottom portion of rotating bracket  40  may be positioned (in the open position shown in  FIG. 2 ) to overlap the bottom portion of the bracket  30 , and movably secured thereto using hinge member  82 . The friction member  90  may then be movably secured at one end to the rotating bracket  40  using hinge member  92 , and movably secured at the other end to the supporting bracket  30  using hinge member  91 .  
         [0046]     The shaft of first wire supporter  70  may be inserted into the open end(s) of the supporting hole(s)  36  and moved to engage the holes&#39; short transverse portion(s). The shaft of second wire supporter  72  may similarly be connected with the supporting hole(s)  38 , and the shaft of elastic member  50  may similarly be connected with the supporting hole(s)  34 .  
         [0047]     Portions of the supporting wires  60  may be fitted within the grooves  73  of the second wire supporter  73 , on the side thereof adjacent the top surface  30 A of bracket  30 . Other portions of the supporting wires  60  may be fitted within the grooves  71  of the first wire supporter  70 , on the side thereof opposite the top surface  30 A of the bracket  30 , and passed through the wire slot  32 . Thereafter, the first ends of the wires  60  may be (fixedly or adjustably) secured to the coupling part  44 . With the rotating bracket  40  rotated to the closed position shown in  FIG. 4A , the supporting wires  60  are suitably tensioned, and their second ends are (fixedly or adjustably) attached the spring  56 .  
         [0048]     An exemplary method of installation is now described. For example, the base  20  is positioned on a vertical support surface, such as a wall  10 , such that the base&#39;s longitudinal center axis substantially parallels the horizontal. The base  20  is then fastened to the support surface by inserting a fastener through an opening  23  formed in flanges  22 A and/or  22 B and manipulating the fastener until the base  20  is firmly coupled to the support surface  10 .  
         [0049]     Next, each bracket assembly (i.e. assembled rotating bracket  40 , supporting bracket  30 , supporting wires  60 , wire supporters  70  and  72 , and elastic member  50 ) may be connected to the base  20  and firmly fastened to the support surface  10 . More particularly, a first supporting bracket  30  (left bracket  30  in  FIG. 1 , for example) is positioned such that the clip(s)  37  of its top flanges  31   a  and  31 B engage the raised rib  24 A of the base&#39;s flange  22 A. After aligning the longitudinal axis of the supporting bracket  30  with the vertical, a fastener may be inserted through an opening  35  in a flange  31 A,  31 B,  31 C, and  31 D, and manipulated until the supporting bracket  30  is firmly coupled to the support surface  10 . The remaining supporting bracket  20  (right supporting bracket  20  in  FIG. 1 , for example) may be similarly connected with the base  20  and the support surface  10 , and may be spaced apart from the first bracket assembly at a distance that corresponds to the width of the hanging fasteners (not shown) attached to the rear of the flat panel display apparatus  80 .  
         [0050]     The flat panel display apparatus  80  may be positioned such that its hanging fasteners project through the upper portions of the mounting apertures  42 A and  42 B formed in each rotating bracket  40 , and then moved downward until each of the display&#39;s hanging fasteners slidably engage the narrow bottom portions of each of the mounting apertures  42 A and  42 B.  
         [0051]     In use, a user may grasp the top (or side) of the flat panel display apparatus  80  and apply an external force sufficient to overcome both the frictional force supplied by the friction member(s)  90  and the tensile force supplied by the spring  56  and supporting wires  60 . The applied external force causes the display apparatus  80  (and coupled rotating hinges  40 ) to rotate between the first closed position of  FIG. 4A  and the second open position of  FIG. 4B . As the top portion of the display apparatus  80  moves away from the support surface  10 , the supporting wires  60  coupled to the rotating brackets  40  pull the spring  56  and unroll it from its contracted state. (Movement of the top portion of the display apparatus toward the support surface  10 , is assisted by contraction of the spring  56 .) In this manner, rotational movement away from the support surface  10  may be dampened (slowed) by the extension of spring  56 . Similarly, rotational movement toward the support surface  10  may be assisted by the contraction of the spring  56  (and may be dampened by the friction member  90 ).  
         [0052]     At any point between the first closed position and the second open position, the user may release the display apparatus  80 , and the desired viewing angle will be maintained until another external force is applied. More particularly, the display panel apparatus  80  becomes secured in a suspended state by a combination of at least the display panel apparatus&#39; weight, the tensile strength of each spring  56 , and the frictional force provided by each friction member  90 .  
         [0053]     In one embodiment of the invention, use of the base  20  may be optional.  
         [0054]     As described above, a wall mount apparatus manufactured according to the principles of the present invention may simplify an assembly process and enhance a usability of the wall mount apparatus by making a portion of the wall mount apparatus easily tiltable to a desired viewing angle.  
         [0055]     Further, a wall mount apparatus manufactured according to the principles of the invention may have fewer components than conventional wall mounts, and consequently, a lower cost of manufacture and/or assembly. Use of supporting wire(s) and an elastic member may further enhance the wall mount apparatus provided by the invention.  
         [0056]     It will be apparent to those skilled in the art that various modifications and variation can be made in the invention without departing from the spirit or scope of the invention. Thus it is intended that the invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
