Abstract
Description
- This application makes reference to, incorporates the same herein, and claims all benefits accruing under 35 U.S.C. §119 from my utility model application entitled Connection Device for Stand Cap of Flat Panel Display filed with the Korean Industrial Property Office on Dec. 31, 1997 and duly assigned Ser. No. 97-44775 by that Office.
- 1. Field of the Invention
- The present invention relates to a flat panel display device, and more particularly, the present invention relates to a flat panel display device having a stand cap which can be easily connected to and disconnected from the display device, and which does not become separated from the display device when the display device is rotated in a horizontal direction to adjust a visual angle of the display device.
- 2. Description of the Related Art
- As shown in FIG. 1, generally, a conventional flat panel display device is pivotally supported by a stand to adjust a visual angle of the display device in horizontal and vertical directions. The conventional flat panel display device includes a
display unit 1 that has a flat panel (not shown) to display an image, and astand 2 that rotatably supports thedisplay unit 1. Ahinge member 3 installed at an upper portion of thestand 20 connects thedisplay unit 1 to thestand 2. As a result, thedisplay unit 1 is rotatably supported by thestand 2 through thehinge member 3. - The
hinge member 3 includes a tilting shaft 5 which is supported by thehinge member 3 in a vertical direction. Thedisplay unit 1 is connected to the tilting shaft 5 through hinge brackets 6 which are pivotally supported at both ends of the tilting shaft 5, respectively. In this way, thedisplay unit 1 is rotated by thehinge member 3 in a horizontal direction and pivoted by the tilting shaft 5 in a vertical direction. When rotatably mounted to thestand 3, thehinge member 3 is covered by a stand cap 4 to prevent foreign substances, such as dust, etc., from entering into thehinge member 3. The stand cap 4 also prevents an exterior of the display device from falling off due to exposure of thehinge member 3. - Snap-recesses or snap-projections (not shown) located inside the
hinge member 3 are snap-fitted with snap-recesses or snap-projections (not shown) located within the stand cap 4, so that the stand cap 4 is snap-fittingly fixed to thehinge member 3. As a result, the stand cap 4 can be easily engaged with and separated from thehinge member 3. - Since the stand cap4 is snap-fittingly fixed to the
hinge member 3 as described above, the stand cap 4 remains in a stationary state when thedisplay unit 1 is pivoted in a vertical direction, but is rotated along with thehinge member 3 when thedisplay unit 1 is rotated in a horizontal direction. - In the conventional flat panel display device, however, when the stand cap4 is rotated horizontally with the
hinge member 3, the snap-fitting between thehinge member 3 and the stand cap 4 eventually is released, so that the stand cap 4 becomes separated from thehinge member 3. When thehinge member 3 and the stand cap 4 become separated, foreign substances such as dust, etc., enter into thehinge member 3, corrupting the functional capabilities of thehinge member 3 and thedisplay unit 1. - Accordingly, it is an object of the present invention to provide a flat panel display device having a stand cap which can be easily connected to and disconnected from the display device, and is prevented from being separated from the display device when the display device is rotated in a horizontal direction to adjust a visual angle of the display device.
- The above and other objects of the present invention are achieved by providing a flat panel display device that includes a display unit to display an image, and a stand that has a circular recess, to support the display unit. The flat panel display device also includes a hinge member that has a ring-shaped rotation member rotatably fixed to the circular recess of the stand, and a holder, fixed to the circular recess of the stand, to secure the rotation member in the stand. A bracket case is fixed to the rotation member and the display unit, and a fastener fixes a stand cap to the hinge member to cover the hinge member.
- The stand cap has a boss that extends toward the hinge member and is connected to the hinge member by the fastener.
- The above and other objects of the present invention are also achieved by providing a flat panel display device that includes a display unit to display an image, and a stand, that has a circular recess, to support the display unit. The flat panel display device also includes a hinge member that has a ring shaped rotation member that is rotatably fixed to the circular recess of the stand, and a holder fixed to the circular recess of the stand to fix the rotation member in the stand. A bracket case is fixed to the rotation member and the display unit, and a stand cap is fixed to the hinge member by a fastener to cover the hinge member. The stand cap has a boss which extends toward the hinge member and is connected to the hinge member by the fastener.
- The boss has an end face that makes contact with the rotation member when the stand cap is fixed to the hinge member. The preferred embodiment of the present invention may also include a projection formed at a rear portion of the rotation member and a locking member located on the stand cap that locks to the projection. In addition, a plurality of grooves may be formed at inner sides of the bracket case in which a plurality of ribs located on the stand cap are respectively inserted, with the grooves and the ribs extending vertically and parallel to each other. Furthermore, a pair of convex portions may be included at an inner circumference of the rotation member, and a pair of hooks located on the stand cap are hooked to respective ones of the convex portions.
- The above and other objects of the present invention are still further achieved by providing a flat panel display device that includes a stand that has a circular recess to support a display unit, and a hinge member, having a ring-shaped rotation member rotatably fixed to the circular recess of the stand. A stand cap is fixed to the rotation member to cover the hinge member, to rotate with the rotation member, and is prevented from being separated from the hinge member as the display unit is rotated.

holder 23 includes a plurality ofbosses 23 a, a plurality ofholes 23 b, and a pair of claws 38 (only one is shown) located at a lower surface of theholder 23. The pair ofclaws 38 are parallel to each other, extend downward toward therotation member 22, and pass through anopening 22 b of therotation member 22. Thebosses 23 a are positioned above thecylindrical bodies 21 a that are arranged at regular intervals in thecircular recess 21, and each of thepins 21 b located about thecircular recess 21 are inserted intorespective holes 23 b of theholder 23 when theholder 23 is assembled to thecircular recess 21. Thereafter,fasteners 24, such as bolts, for example, are fastened to thebosses 23 a through thecylindrical bodies 21 a. Theclaws 38 are hooked under and come in contact with a lower portion of therotation member 22 to prevent theholder 23 from being separated from therotation member 22 when an upward force is extended on theholder 23. - As illustrated in FIGS. 3, 4, and6, when the
hinge member 30 is mounted to thestand 20, thedisplay unit 10 is pivotally supported vertically and horizontally by thestand 20, and thestand cap 40 is assembled to thehinge member 30 to prevent foreign substances such as dust, etc., from entering into thehinge member 30. In addition, thestand cap 40 covers and prevents thehinge member 30 from outside exposure. Thestand cap 40 is preferably made of a plastic material, and includes aboss 34 with an end face that extends downward, toward thehinge member 30. As illustrated in FIG. 6, theboss 34 is connected to thehinge member 30 by thefastener 29. Theboss 34 preferably has a length that enables the end face of theboss 34 to be in direct contact with an upper surface of the lower portion of therotation member 22, so that thestand cap 40 firmly engages thehinge member 30 when thestand cap 40 is fixed to thehinge member 30. - The
stand cap 40 is rotated with therotation member 22 during rotation of thedisplay unit 20 when adjusting a visual angle of thedisplay unit 20. Accordingly, thestand cap 40 is prevented from being separated from thehinge member 30 due to the direct contact of theboss 34 of thestand cap 40 with thehinge member 30 during rotation of thedisplay unit 10. - In addition, as illustrated in FIGS.3-5, the preferred embodiment of the present invention may also include a locking
member 33 that is formed along a rear side of thestand cap 40 to enable thefastener 29 to be more easily fastened to theboss 34 of thestand cap 40 when thestand cap 40 is assembled to thehinge member 30. That is, the lockingmember 33 is locked to theprojection 28 prior to thefastener 29 being fastened to theboss 34, so that theboss 34 can be more precisely positioned above theholes 22 a located in therotation member 22, through which thefastener 29 passes when being fastened to theboss 34. - In addition, the
stand cap 40 also includes a plurality of parallel, vertically extendingribs 31. Theribs 31 are engaged with thegrooves 26 a formed along the inner sides of thebracket case 26, respectively, when thestand cap 40 is assembled to thehinge member 30. Since theribs 31 are engaged with thegrooves 26 a, thestand cap 40 is prevented from moving back and forth when thestand cap 40 is assembled to thehinge member 30 or when thedisplay unit 10 is rotated. - The
stand cap 40 also includes a pair ofhooks 32 formed at the inner portion of thestand cap 40 that come in contact with respectiveconvex portions 27 of therotation member 22. Since thehooks 32 are in contact with theconvex portions 27 of therotation member 22, thestand cap 40 can be maintained in position when thefastener 29 is fastened to theboss 34 during assembly of thestand cap 40 to thehinge member 30, i.e., therotation member 22. As a result, thefastener 29 can be more easily fastened to theboss 34. - As described above, in the flat panel display device according to the preferred embodiment of the present invention, the
stand cap 40 is prevented from being separated from thehinge member 30 when thedisplay unit 10 is rotated, since thestand cap 40 is firmly assembled to therotation member 22 by thefastener 29. - Furthermore, in the flat panel display device according to the present invention, the
stand cap 40 can be more easily assembled to thehinge member 30 since various means are provided to keep thestand cap 40 in place before thestand cap 40 is assembled to thehinge member 30 by thefastener 29. - Accordingly, the flat panel display device according to the present invention is prevented from being separated from the hinge member and prevents foreign substances, such as dust, etc., from entering into the hinge member.
- Although a preferred embodiment of the present invention has been shown and described, it will be appreciated by those skilled in the art that changes may be made in the embodiment without departing from the principles and spirit of the invention, the scope of which is defined in the claims and their equivalents.
