Before the present invention is described in greater detail, it should be noted that same reference numerals have been used to denote like elements throughout the specification.
Referring to FIGS. 1 to 4, the first preferred embodiment of a display frame according to the present invention is adapted to hold a framed picture 11 and a flat panel device 12, such as a tablet PC (see FIGS. 4 and 5), and to be mounted to a support, such as an upright wall, a display stand, and the like. The display frame of this embodiment is shown to comprise a frame body 2, a front profile frame 23, a pair of linking units 25, a holding unit 3, a locking unit 5, and a fastening unit 4.
The frame body 2 includes a rear wall 21 with four through holes 211 therein, a surrounding wall 22 which extends from the rear wall 21 in a transverse direction and which includes right and left walls 222,221 opposite to each other in a longitudinal direction transverse to the transverse direction, and upper and lower walls 223,224 opposite to each other in an upright direction transverse to the longitudinal and transverse directions so as to define a receiving space 24 with an access opening which is opposite to the rear wall 21 and which faces forwardly and in the transverse direction.
The front profile frame 23 has a proximate end 232 which is mounted pivotally on the lower wall 224 about a first pivoting axis (X) such that a distal end 233 thereof is turnable about the first pivoting axis (X) between an open position, where a viewing window 231 of the front profile frame 23 that is disposed between the proximate and distal ends 232,233 is remote from the access opening to permit placement of the flat panel device 12 in the receiving space 24, and a closed position, where the viewing window 231 is close to the access opening so as to cover the access opening (see FIG. 6). A decorative frame 26 is detachably mounted on a front surface of the front profile frame 23.
Each of the linking units 25 includes a pivot mount 252 which is mounted on the front profile frame 23 proximate to the proximate end 232 and which extends to terminate at an anchor end distal from the viewing window 231. A linkage 251, in the form of a lever, has a pivot end 2511 which is pivotally mounted on the anchor end of the pivot mount 252 about a pivot axis, and a connecting end 2512 which is opposite to the pivot end in a radial direction relative to the pivot axis and which is turnable between first and second positions that correspond to the open and closed positions of the front profile frame 23, respectively.
The holding unit 3 includes a holding tray 32, a backing member 31, and two biasing members 33. The holding tray 32 is adapted to be disposed underneath a bottom wall of the flat panel device 12, and is disposed to be movable relative to the frame body 2 in the transverse direction between an extending position, where the holding tray 32 extends forwardly and outwardly of the access opening, and a retreat position, where the holding tray 32 retreats into the receiving space 24. In particular, a keyway 226, in the form of a slot, is formed in each of the right and left walls 222,221, and is elongated in the transverse direction. A key 253 is disposed on the holding tray 32, and has an intermediate portion extending from the holding tray 32 in the longitudinal direction to terminate at a coupling end. The intermediate portion of the key 253 is inserted into and is slidable relative to the keyway 226 so as to move the holding tray 32 between the extending and retreat positions. Preferably, lower right and left sliding pins 254 are respectively disposed on right and left sides of the holding tray 32, and extend respectively towards the right-and left walls 222,221 so as to be slidable along lower sliding slots 225 formed respectively in the right and left walls 222,221 and extending in the transverse direction, thereby stabilizing the movement of the holding tray 32. In addition, the holding tray 32 includes a front barrier wall 321 which confronts and which is disposed distal from the rear wall 21. An electrical connecting unit 324 is disposed under the holding tray 32 for electrical connection with the flat panel device 12.
Moreover, the connecting end 2512 of the linkage 251 has an inner peripheral bearing wall which defines a hole and which has the coupling end of the key 253 journalled thereon so as to serve as a coupling member. As such, when the connecting end 2512 of the linkage 251 is moved between the first and second positions, the holding tray 32 is moved between the extending and retreat positions, respectively. Besides, pivotal connection of the proximate end 232 of the front profile frame 23 with the lower wall 224 of the frame body 2 about the first pivoting axis (X) enables stabilized angular movement of the connecting end 2512 of the linkage 251.
The backing member 31 includes a lower abutment portion 313 which is spaced apart from the front barrier wall 321 of the holding tray 32 in the transverse direction and which is slidable on the holding tray 32 to adjust the distance between the lower abutment portion 313 and the front barrier wall 321 so as to accommodate the thickness of the bottom wall of the flat panel device 12 and so as to permit abutment of the flat panel device 12 thereagainst (see FIG. 4). With reference to FIGS. 2 and 5, the backing member 31 defines an inserting space 317 for insertion of the framed picture 11 therein, and two sliding slots 318 extending in the upright direction.
Furthermore, two upper right and left sliding plates 34 are disposed pivotally and respectively on right and left sides of the backing member 31, and extend respectively towards the right and left walls 222,221 so as to be slidable along upper sliding slots 227 formed respectively in the right and left walls 222,221 and extending in the transverse direction, thereby stabilizing the movement of the backing member 31.
Referring to FIGS. 3 and 5, each of the biasing members 33 includes two leaf springs 331, each of which has two ends secured on the rear wall 21, and respectively provided with sliding blocks 332. The sliding blocks 332 are slidably inserted into the sliding slots 318 in the backing member 31 such that the backing member 31 is biased by the biasing members 33 towards the front barrier wall 321 of the holding tray 32, thereby retaining the bottom wall of the flat panel device 12 between the lower abutment portion 313 of the backing member 31 and the front barrier wall 321.
Referring to FIGS. 2 and 6, the locking unit 5 includes locking and locked portions 51,52 which are respectively disposed on the distal end 233 of the front profile frame 23 and the upper wall 223 of the frame body 2, and which are engaged with each other so as to fasten the front profile frame 23 to the frame body 2 in the closed position.
In use, referring to FIGS. 3 and 4, when the front profile frame 23 is in the open position, the flat panel device 12 is placed on the holding tray 32, and the bottom wall thereof is retained between the front barrier wall 321 and the lower abutment portion 313 of the backing member 31, such that the backing member 31 is inclined rearwardly towards the rear wall 21. Referring to FIG. 6, the front profile frame 23 is then moved from the open position to the closed position such that the holding tray 32 is moved to the retreat position, where the holding tray 32 retreats into the receiving space 24 by means of the linking units 25. The front profile frame 23 is subsequently fastened to the frame body 2 by the locking unit 5. Thus, the flat panel device 12 can be held in the display frame for presentation of multimedia data through the viewing window 231. Besides, when the locking unit 5 is released, and the front profile frame 23 is moved from the closed position to the open position, the holding tray 32 can be moved to the extending position by the biasing members 33 for facilitating removal of the flat panel device 12 from the receiving space 24.
