FIELD OF THE INVENTION
The invention relates to racks and more particularly to a rack apparatus comprising a mother rack and a daughter rack so that for example, two computer displays may be placed the mother rack and the daughter rack respectively in a first configuration, a computer display may be placed on the mother rack and a laptop computer may be placed on the daughter rack respectively in a second configuration.
BACKGROUND OF THE INVENTION
Computer, communication, and consumer electronics (3C) are popular throughout the world and they are characterized by short popular life. Thus, many enterprises invest great resources in the research and development of 3C products.
Many people own at least one of a personal computer (PC), a laptop computer, a tablet computer, and a mobile phone such as smart phone. Modern smart phones have many functions similar to a PC and thus are multifunctional.
As for PCs, they are typically used in home or office due to stable power, quality screen, large keyboard, mouse, high capacity memory, etc. Typically a PC comprises a monitor, a keyboard, and a mouse.
As for mobile phones, tablet computers and laptop computers, they are light weight and portable. Thus, frequent charging is inevitable for their use. Further, how to support them and properly connect them is a big issue to be addressed. It is necessary to take holding above electronic devices in place into consideration when using them in an indoor environment. Sufficient space for accommodating them is also an issue to be addressed especially when the space is limited.
Further, it is often that a number of PCs, laptop computers, tablet computers and displays are placed on a table. Thus, how to orderly place them on the table without being messy is another issue to be addressed.
U.S. Pat. No. 10,251,477B1 to Huang discloses a detachable, multifunctional rack for electronic devices includes a rectangular platform including a lower board secured to an underside, two sets of a plurality of hollow members on two sides of the lower board respectively, and a space under the lower board; two L-shaped supports mounted to two sides of the platform respectively, each support including a horizontal member releasably secured to either side of the platform, a vertical member releasably secured to the horizontal member, and a plurality of aligned, spaced tubular members on one side of the horizontal member; and two pins each passing through one set of the hollow members and the tubular members at either side of the platform to fasten the platform and the supports together.
While the device enjoys its success in the market, continuing improvements in the exploitation of rack of this type are constantly sought.
SUMMARY OF THE INVENTION
It is therefore one object of the invention to provide a rack apparatus, comprising a mother rack including a rectangular platform member on a top, a left L-shaped support pivotably secured to a left side of the platform member, a right L-shaped support pivotably secured to a right side of the platform member, a left groove disposed on a left side of the platform member, a right groove disposed on a right side of the platform member, and a space member disposed under the platform member; and a daughter rack including a rectangular platform element on a top, a left leg pivotably secured to a left side of the platform element, a right leg pivotably secured to a right side of the platform element, a pivotal limit member disposed on a front end of the platform element, a pivotal surface disposed rearward of the pivotal limit member, a rear support leg having a first end pivotably secured to a back surface of the pivotal surface and a second end pivotably secured to the platform element, and a space element under the platform element; wherein the left leg is configured to fasten in the left groove and the right leg is configured to fasten in the right groove respectively.
