1. Field of the Invention
The invention relates to a display-supporting frame, more particularly to a display-supporting frame with first and second rods connected to each other through a plurality of fasteners.
2. Description of the Related Art
Conventional display-supporting frames normally include a base frame and a panel frame that is connected to the base frame for mounting of a display panel of a display thereon. The conventional display-supporting frames are disadvantageous in that they require different dies for punching devices used to make different sizes of components of the base and panel frames when fabricating different sizes of the display-supporting frames.
Therefore, the object of the present invention is to provide a display-supporting frame that is capable of overcoming the aforesaid drawback associated with the prior art.
Accordingly, a display-supporting frame of the present invention comprises: a plurality of first rods, each of which has two opposite first side walls that are opposite to each other in a first direction, and two opposite second side walls that are opposite to each other in a second direction transverse to the first direction, one of the first side walls being formed with a plurality of first hole units aligned along the length of the respective one of the first rods, one of the second side walls being formed with a plurality of second hole units aligned along the length of the respective one of the first rods, each of the first hole units cooperating with an adjacent one of the second hole units to define a plane transverse to the first and second side walls such that the first and second hole units in the adjacent pair are respectively located at two sides of the plane; a plurality of second rods, each of which has two opposite end faces, and each of which is formed with a locking hole unit that extends along the length of the respective one of the second rods through the end faces; and a plurality of fasteners for fastening the first rods to the second rods through extension of each of the fasteners through a selected one of the first hole units and the second hole units in a respective one of the first rods, and into the locking hole unit in a respective one of the second rods to engage the respective one of the second rods.
Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiments with reference to the accompanying drawings, of which:
Before the present invention is described in greater detail with reference to the accompanying preferred embodiments, it should be noted here in that like elements are denoted by the same reference numerals throughout the disclosure.
Referring to FIGS. 1 to 3, the first preferred embodiment of a display-supporting frame according to the present invention is shown to include a base frame part 4 and a panel frame part 5 connected to the base frame part 4.
The base and panel frame parts 4, 5 are assembled from a plurality of first rods 1, a plurality of second rods 2, and a plurality of fasteners 3.
Each of the first rods 1 has a cross-section that is rectangular in shape, and further has two opposite first side walls 11 that are opposite to each other in a first direction (X), and two opposite second side walls 13 that are opposite to each other in a second direction (Y) transverse to the first direction (X). One of the first side walls 11 is formed with a plurality of first hole units 18 aligned along the length of the respective one of the first rods 1. One of the second side walls 13 is formed with a plurality of second hole units 19 aligned along the length of the respective one of the first rods 1. Each of the first hole units 18 cooperates with an adjacent one of the second hole units 19 to define a plane transverse to the first and second side walls 11, 13 such that the first and second hole units 18, 19 in the adjacent pair are respectively located at two sides of the plane. The aforesaid plane is parallel to the X-Y plane defined by the first and second directions (X, Y).
Each of the second rods 2 has two opposite end faces 23, and is formed with a locking hole unit 28 that extends along the length of the respective one of the second rods 2 through the end faces 23.
The fasteners 3 fasten the first rods 1 to the second rods 2 through extension of each of the fasteners 3 through a selected one of the first hole units 18 in said one of the first side walls 11 and the second hole units 19 in said one of the second side walls 13 of a respective one of the first rods 1, and into the locking hole unit 28 in a respective one of the second rods 2 to engage the respective one of the second rods 2.
In this embodiment, the other of the first side walls 11 of each of the first rods 1 is formed with a plurality of first access openings 14 that are respectively registered with the first hole units 18 for access to the first hole units 18 so as to permit tightening and loosening of the respective ones of the fasteners 3, and the other of the second side walls 13 of each of the first rods 1 is formed with a plurality of second access openings 16 that are respectively registered with the second hole units 19 for access to the second hole units 19 so as to permit tightening and loosening of the respective ones of the fasteners 3.
Each of the first and second hole units 18, 19 in the respective first and second side walls 11, 13 of each of the first rods 1 includes two through-holes 12. The locking hole unit 28 of each of the second rods 2 includes two locking holes 24 that are respectively registered with the through-holes 12 in the respective one of the first and second side walls 11, 13 of the respective one of the first rods 1.
In this embodiment, each of the second rods 2 has a cross-section that is I-shaped (see
Each of the fasteners 3 is in the form of a screw having a screw head 32 and a threaded shank 31. Each of the second rods 2 has an inner thread 26 formed in each locking hole 24 of the locking hole unit 28. Each of the fasteners 3 engages threadedly the inner thread 26 in the respective one of the locking holes 24 of the locking hole unit 28 in the respective one of the second rods 2.
During manufacture of the display-supporting frame, aluminum alloy is first extruded into elongated rods with structures corresponding respectively to those of the first and second rods 1, 2. The elongated rods are subsequently subjected to punching and cutting into desired lengths of the first and second rods 1, 2 that correspond to the required dimensions of the display-supporting frame.

By forming the first and second hole units 18, 19 in each of the first rods 1 and the locking hole unit 28 in each of the second rods 2, different lengths of the first and second rods 1 can be obtained by simply cutting the aforesaid elongated rods, which are respectively formed with the first and second hole units 18, 19 and the locking hole unit 28, into desired lengths that correspond to the dimensions of the display-supporting frame to be manufactured. As such, fabrication of different sizes of the base frame part 4 and the panel frame part 5, i.e., different sizes of the display-supporting frame, is simpler than the conventional display-supporting frame, and the manufacturing costs can be considerably reduced.
While the present invention has been described in connection with what is considered the most practical and preferred embodiments, it is understood that this invention is not limited to the disclosed embodiments but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
