Referring to FIG. 1, a display, for example, an LCD TV 1 is shown comprising a display panel 11 and a base 12. The display panel 11 comprises a front face panel 111 and a back cover 112. The back cover 112 covers the back side of the face panel 111. The base 12 comprises a front holder shell 121 and a back holder shell 122. The back holder shell 122 is fastened to the front holder shell 121.
Referring to FIG. 2 and FIG. 1 again, a quick detachable bearing bracket in accordance with the first embodiment of the present invention is shown provided between the display panel 11 and the base 12. The quick detachable bearing bracket comprises a locating barrel 4, a resilient retaining rod 5, and a coupling barrel 3.
The locating barrel 4 is secured to the base 12 between the front holder shell 121 and the back holder shell 122. According to this embodiment, the base 12 comprises a first rib 123 formed integral with the front holder shell 121, and a second rib 124 formed integral with the back holder shell 122 and corresponding to the first rib 123. The locating barrel 4 has two locating grooves 46 symmetrically formed in the periphery at two opposite sides and respectively coupled to the first rib 123 and second rib 123 of the base 12. After the front holder shell 121 and the back holder shell 122 have been fixedly fastened together, the locating barrel 4 is locked to the base 12 between the front holder shell 121 and the back holder shell 122.
The locating barrel 4 is comprised of an inner barrel member 401 and an outer barrel member 402. The aforesaid two locating grooves 46 are formed in the periphery of the outer barrel member 402 at two opposite sides. The inner barrel member 401 comprises a tubular body 41 inserted through the outer barrel member 402 and partially protruding over the front side of the outer barrel member 402, and a longitudinal slot 42 formed in the tubular body 41 at one side. The outer barrel member 402 comprises front engagement means 45. According to this embodiment, the front engagement means 45 is comprised of two beveled notches 451 bilaterally formed in the front side of the outer barrel member 402.
The resilient retaining rod 5 is mounted in the inner barrel member 401 of the locating barrel 4 and fixedly fastened to the rear side of the inner barrel member 401 with two screws 71, comprising a transversely protruding front retaining portion 51 insertable into the longitudinal slot 42 of the inner barrel member 401 and a transversely protruding middle press portion 52.
According to this embodiment, the inner barrel member 401 of the locating barrel 4 has an opening 43 in the peripheral wall in line with the longitudinal slot 42 near the rear side. The outer barrel member 402 has an opening 44 in the peripheral wall corresponding to the opening 43 of the inner barrel member 401. The middle press portion 52 of the resilient retaining rod 5 is insertable through the openings 43 and 44 to the outside of the locating barrel 4. Further, the back holder shell 122 of the base 12 has a small through hole 125 corresponding to the middle press portion 52 of the resilient retaining rod 5.
The coupling barrel 3 has the front end thereof fixedly fastened to the display panel 11 between the front face panel 111 and the back cover 112. According to this embodiment, the coupling barrel 3 has the front end terminating at a mounting plate 33 fixedly fastened to the front face panel 111 and the back cover 112 with screws 72, and the rear end terminating at engagement means 31. According to this embodiment, the engagement means 31 comprises two protrusions 311 corresponding to the beveled notches 451. The coupling barrel 3 further has a longitudinal slot 32 corresponding to the longitudinal slot 42 of the inner barrel member 401.
Referring to FIGS. 3 ̃5 and FIGS. 1 and 2 again, when wishing to affix the display panel 11 to the base 12, the coupling barrel 3 is sleeved onto the tubular body 41 of the inner barrel member 401 to force the protrusions 311 into the beveled notches 451 of the outer barrel member 402 and to prevent relative rotary motion between the coupling barrel 3 and the locating barrel 4, allowing the transversely protruding retaining portion 51 of the resilient retaining rod 5 to engage into the longitudinal slot 42 of the inner barrel member 401 and the longitudinal slot 32 of the coupling barrel 3. Therefore, the display panel 11 is locked to the base 12 as shown in FIG. 5.
Referring to FIG. 6 and FIGS. 1 and 2 again, when wishing to remove the display panel 11 from the base 12, a pointed object (see the arrowhead sign in FIG. 6) is inserted through the small through hole 125 (see FIG. 1) to force the middle press portion 52 of theresilient retaining rod 5 backward and to further disengage the front retaining portion 51 inserted into the longitudinal slot 32 of the coupling barrel 3 (see FIG. 6), and then the coupling barrel 3 is removed from the locating barrel 4 to separate the display panel 11 from the base 12. When wishing to separate the display panel 11 from the base 12, the user must use a pointed object and insert it through the small through hole 125 to disengage the resilient retaining rod 5 from the coupling barrel 3. This design can prevent the accidental disengagement of the retaining rod 5 from the coupling barrel 3, such as by a child.
In order to present reverse action of the resilient retaining rod 5 after the middle press portion 52 of the resilient retaining rod 5 has been forced backward, the user can rotate the coupling barrel 3 relative to the inner barrel member 401 through an angle, for example, 30° to stop one protrusion 311 against the front retaining portion 51 of the resilient retaining rod 5, facilitating removal of the coupling barrel 3 from the locating barrel 4.
The aforesaid design of quick detachable bearing bracket is simple, cost effective and labor saving. After dismounting of the display panel 11 from the base 12, the user can fasten the display panel 11 to the base 12 again in a different angular position.
FIG. 7 is a perspective assembly view of the second embodiment of the present invention. This second embodiment is substantially the same as the aforesaid first embodiment with the exception that the locating barrel 811 of the quick detachable bearing bracket is formed integral with the base, referenced by 81. The locating barrel 811 has the same structure as the locating barrel 4 of the aforesaid first embodiment. The base 81 can be hung on the wall, or stood on the top of a table. After disconnection of the display panel 11 from the locating barrel 811, the display panel 11 can be fastened to the locating barrel 811 again in another angular position.
FIG. 8 is a perspective assembly view of the third embodiment of the present invention. According to this embodiment, the base, referenced by 82, has a mounting face 821 that can be affixed to a wall 6 for enabling the display panel 11 to be placed on the wall 6.
Although the present invention has been explained in relation to its preferred embodiments, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
