Detailed Description of the Preferred Embodiment
[0023] Please refer to FIG. 3 and FIG. 4 . FIG. 3 is a back perspective view of a portable media center according to the present invention. FIG. 4 is an exploded view of an ejectable stand according to the present invention.
[0024] In this embodiment, an ejectable stand may be utilized in a portable media center 1. The portable media center 1 comprises a back 10 with an extended depression 11. The extended depression 11 has a first end 111 and a second end 112, and the first end 111 has a fastening lip 12.
[0025] The ejectable stand comprises a stand body 2, and a slide switch 3.
[0026] In this embodiment, the stand body 2 is mounted in the extended depression 11 of the portable media center 1. The stand body 2 comprises a front end 21, a rear end 22, an outer face 24, an inner face 26 and a bottom strip 27. The rear end 22 is pivotally connected to the second end 112 of the extended depression 11, and the rear end 22 has a torsion spring 6, an axle 5 and an axle opening 23. The front end 21 has a stop 25.
[0027] The torsion spring 6 encloses the axle 5 and pushes against both the stand body 2 and the extended depression 11. The axle 5 is disposed in the axle opening 23 and pivotally connected to the second end 112 of the extended depression 11. The bottom strip 27 covers inner face 26.
[0028] Please refer to FIG. 4 , FIG. 5 and FIG. 6 . FIG. 4 is an exploded view of an ejectable stand according to the present invention. FIG. 5 shows the ejectable stand in a closed configuration according to the present invention. FIG. 6 is a cross-sectional view of a region depicted in FIG. 5 . The slide switch 3 is slidably mounted on outer face 24 of the stand body 2. The slide switch 3 comprises an outer face 32 and a fastening hook 31. The outer face 32 has a plurality of anti-slip ridges 33 to increase friction so that the ejectable stand can be opened easily.
[0029] In FIG. 5 and FIG. 6 , the fastening hook 31 corresponds to the fastening lip 12 of the portable media center 1. The fastening hook 31 further comprises a compression spring 4 and a column 311. The compression spring 4 pushes against both the fastening hook 31 and the stop 25 of the stand body 2. The compression spring 4 provides an elastic force that drives the fastening hook 31 to slide the slide switch 3 on the stand body 2, fastening the fastening hook and the fastening lip 12 together.
[0030] The column 311 extends towards to the stop 25. The compression spring 4 encloses the column 311 and pushes against the fastening hook 31 and the stop 25. This arrangement prevents the compression spring 4 from falling, and the column 311 also maintains the direction of the elastic force imparted by the compression spring 4, ensuring the compression spring 4 pushes against, and between, the fastening hook 31 and the stop 25.
[0031] Please refer to FIG. 7 and FIG. 8 . FIG. 7 shows the ejectable stand capable of being in an OPEN state according to the present invention. FIG. 8 is a cross-sectional view of a region depicted in FIG. 7 .
[0032] As shown in FIG. 5 and FIG. 6 , the fastening hook 31 of the slide switch 3 is pushed by the compression spring 4, and fastened with the fastening lip 12, so the stand body 2 is contained within the extended depression 11 of the portable media center 1.
[0033] As shown in FIG. 7 and FIG. 8 , when the slide switch 3 is moved backward by a user, the compression spring 4 of the fastening hook 31 of the slide switch 3 is pressed, and leaves the fastening lip 12 of the portable media center 1; meanwhile, the torsion spring 6 provides an elastic force to eject and extend the stand body 2 from the extended depression 11 at a predetermined angle, thus providing support for the portable media center 1 at an angle that provides a comfortable viewing angle for the user.
[0034] When the user pushes the stand body 2 back into the extended depression 11 of the portable media center 1, the fastening hook 31 of the slide switch 3 utilizes the elastic force provided by the compression spring 4 to fasten with the fastening lip 12, and so the stand body 2 remains disposed within extended depression 11 of the portable media center 1.
[0035] The stand body 2 and the slide switch 3 are integrated together to reduce the number of the parts. Moreover, the slide switch 3 has large activation area, and so is easy to operate. The user can open the ejectable stand with the touch of a single finger.
[0036] Although the present invention has been explained in relation to its preferred embodiment, 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.
