DETAILED DESCRIPTION OF THE INVETION
To facilitate understanding of the object, characteristics and effects of this present disclosure, embodiments together with the attached drawings for the detailed description of the present disclosure are provided.
Referring to FIG. 2 through FIG. 4, the present disclosure provides an adjustable embedded display unit backframe 100 which comprises a backframe base 1 and a plurality of engaging assemblies 2.
Referring to FIG. 3A and FIG. 3B, the backframe base 1 has a front 11 for holding a display screen D and a back 12 opposing the front 11. The back 12 has a plurality of slide rails 3. In this embodiment, the back 12 of the backframe base 1 is rectangular, but the present disclosure is not limited thereto. In a variant embodiment of the present disclosure, the back 12 is square or is of any shape suitable for a wall W.
The engaging assemblies 2 are disposed in the slide rails 3, respectively, and slidable relative to the backframe base 1. The engaging assemblies 2 each have an engaging component 21 for engaging with the wall W. The wall W has an opening H. The opening H may be smaller than the embedded display unit backframe 100 in terms of size, but the smaller opening H does not place any limitation on the mounting process of the embedded display unit backframe 100. To mount the embedded display unit backframe 100 in place, as shown in FIG. 3A, a user holds the backframe base 1 in such a manner that the back 12 faces the wall W. Afterward, as shown in FIG. 3B, the user pushes the backframe base 1 in such a manner that the back 12 presses against the wall W while adjusting the engaging components 21, so as for the engaging components 21 to be exposed from the opening H and thus engaged with the wall W. In this embodiment, as shown in FIG. 2, the engaging components 21 are each L-shaped such that the wall W is clamped by the backframe base 1 and the engaging components 21, but the present disclosure is not limited thereto. In a variant embodiment of the present disclosure, the engaging components 21 are of any type, shape or mechanism and are any standard means such that the backframe base 1 can be connected and fixed to the wall W by the engaging components 21.
Referring to FIG. 3B, since the engaging assemblies 2 are each slidable relative to the backframe base 1 and thus adjustable in position, the adjustable embedded display unit backframe 100 is suitable for the wall W with an opening of any size, sparing the hassle of boring an opening in the wall W anew in an attempt to suit the backframe base 1. Referring to FIG. 3B, the opening of the wall W is of size H, size H1 larger than size H, or size H2 smaller than size H; however, regardless of the size of the opening of the wall W, the user can mount the embedded display unit backframe 100 on the wall W by sliding the engaging assemblies 2, thereby not only sparing the hassle of boring an opening in the wall W anew, but also ensuring that the use of embedded display units is easy and flexible.
Furthermore, in an embodiment, as shown in FIG. 4, the engaging assemblies 2 each comprise a sliding component 22. The bottom ends of the sliding components 22 are disposed in the slide rails 3, respectively. One end of each engaging component 21 is pivotally connected to a corresponding one of the sliding components 22, allowing the engaging component 21 to rotate relative to the sliding component 22. Therefore, to engage the engaging assemblies 2 with the wall W, the user rotates the engaging components 21 until the engaging components 21 face the center of the backframe base 1. After the backframe base 1 has been positioned in place, the user rotates the engaging components 21 such that the engaging components 21 engage with the wall W.
Furthermore, in an embodiment, as shown in FIG. 4, the slide rail 3 comprises a limiting rail 31. A hollow space S is disposed between the slide rail 3 and the body of the backframe base 1. The limiting rail 31 is disposed on the back 12 and has a plurality of engaging recesses 311. The engaging recesses 311 are spaced apart by a fixed distance. The sliding component 21 slides along the limiting rail 31. The bottom end of the sliding component 21 engages with one of the engaging recesses 311. Therefore, the engaging assemblies 2 not only slide along the slide rails 3 but are also selectively confined to one of the slide rails 3.
Furthermore, in an embodiment, as shown in FIG. 4, the bottom end of the sliding component 22 has a leaf spring 221 for engaging with one of the engaging recesses 311. The leaf spring 221 is resilient and thus deforms temporarily under an applied force to therefore escape from the engaging recess 311. As soon as the applied force perishes (for example, when the engaging assemblies 2 have been slid to an ideal position), the leaf spring 221 restores its original form and thus engages with the nearest engaging recess 311. Therefore, the engaging assemblies 2 can be easily, efficiently moved and fixed in place.
Furthermore, in an embodiment, as shown in FIG. 4, the leaf spring 221 comprises a resilient arm 221a and a latch portion 221b. The resilient arm 221a connects to the latch portion 221b. The latch portion 221b engages with one of the engaging recesses 311. Therefore, the latch portion 221b will be separated from the engaging recesses 311 temporarily, provided that a force is applied to the resilient arm 221a. As soon as the applied force perishes, the latch portion 221b restores its original form and thus engages with one of the engaging recesses 311.
Furthermore, in an embodiment, as shown in FIG. 4, each sliding component 22 further comprises a bolt 222, a fastening element 223 and a nut element 224. The fastening element 223, engaging component 21 and nut element 224 are screwed to the bolt 222 consecutively. The fastening element 223 and the leaf spring 221 are fastened to each other.
Furthermore, in an embodiment, as shown in FIG. 4, the limiting rail 31 has two mounting openings 32 and two rails 33. The two rails 33 are in communication with the two mounting openings 32, respectively. The engaging recesses 311 are disposed between the two rails 33. Two wing portions 223a at the bottom end of the fastening element 223 correspond in shape to the two mounting openings 32, respectively. The fastening element 223 further has two arm portions 223b perpendicular to the two wing portions 223a, respectively. The widths of the two arm portions 223b are suitable for the two rails 33, respectively. Therefore, after the fastening element 223, bolt 222 and leaf spring 221 have been mounted in place, the wing portions 223a of the fastening element 223 pass through the mounting openings 32 so as to enter the slide rail 3; meanwhile, the arm portions 223b slide within the rails 33 and get engaged with the limiting rail 31 because of the structure thereof.
Furthermore, in an embodiment, as shown in FIG. 3B, the engaging assemblies 2 are in the number, but the present disclosure is not limited thereto. In a variant embodiment of the present disclosure, the number and position of the engaging assemblies 2 are subject to changes, depending on the requirements for the backframe base 1 and the wall W.
Furthermore, in an embodiment, as shown in FIG. 3B, the number of the slide rails 3 is greater than or equal to the number of the engaging assemblies 2. Hence, the back 12 has the slide rails 3, and the engaging assemblies 2 are mounted on one/some of the slide rails 3 as needed. Therefore, the use of the engaging assemblies 2 is more flexible.
While the present disclosure has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of the present disclosure set forth in the claims.
