BACKGROUND INFORMATION1. Field of the Invention
The invention relates to the field of cases. More particularly, the invention relates to a size-adjustable case for a laptop computer.
2. Description of the Prior Art
Laptop computers are ubiquitous today. Many users carry their laptop in a special case, to protect it from impact shock and secure it from theft or unauthorized use. Laptop computers come in a wide variety of dimensions, thus, it is not unusual for a laptop user to have to get a new carry case, when she acquires a new laptop.
What is needed, therefore, is a universal laptop computer case that will accommodate the dimensions of conventional laptops. What is further needed is such a case that will securely hold the laptop computer in the case and prevent it from rattling or shifting in the case.
BRIEF SUMMARY OF THE INVENTIONThe invention is a universal computer case comprising a frame that is width and height adjustable, so as to accommodate the size of almost any laptop computer. The universal computer case according to the invention has an upper and a lower lid. The frame is attached to a base plate that is securely mounted in the lower lid. The frame has a width-adjustment slide assembly and a height-adjustment slide assembly. Corner retainers are provided on the corners of the frame for retaining a computer. These slide assemblies are adjusted to the size of the computer to be carried in the case and ideally so, that the computer fits within the corner retainers, without excess room. A press assembly is assembled in the upper lid, which allows the user to adjust a downward press slide. The press slide serves to hold the laptop computer securely against the frame, when the case is closed, and to prevent the computer from banging or rattling against the upper lid, when the universal computer case is carried in a vertical orientation.

DETAILED DESCRIPTION OF THE INVENTIONThe present invention will now be described more fully in detail with reference to the accompanying drawings, in which the preferred embodiments of the invention are shown. This invention should not, however, be construed as limited to the embodiments set forth herein; rather, they are provided so that this disclosure will be complete and will fully convey the scope of the invention to those skilled in the art.
FIG. 1 is a perspective view of auniversal computer case1000 according to the invention. Theuniversal computer case1000 comprises ahard case100, anadjustable base plate200 that is placed within alower lid120, and apress device300 mounted on the inner surface of anupper lid130 of thehard case100.FIG. 2 is an enlarged view of thebase plate200, which comprises apad210 securely and fixedly mounted thebase plate200. A height-and-width adjustingframe220, which is adjustable in a width dimension W and a height dimension H, as indicated by the corresponding arrows inFIG. 2, is mounted on thepad210. Theframe220 includes a width-adjustment slide assembly250 and a height-adjustment slide assembly230. The width-adjustment slide assembly250 includes a width-adjustment slide252 with alatching device264; the height-adjustment slide assembly230 includes arail234 with aslide mechanism236 mounted thereon. In the embodiment shown, the width-adjustment slide assembly250 includes a pair ofslides252 with latching device262. The combination of the height-adjustment slide assembly230 and the width-adjustment slide assembly250 enables bi-directional adjustment of theframe220, so as to accommodate the dimensions of various types and models of computers.
FIGS. 3,4A, and4B illustrate details of the height-and-width adjustingframe220. Thepad210 is formed as a rigid plate and mounted in thelower lid120. In the embodiment shown, thepad210 has a series of holes, for the purpose of reducing the weight of the case. The width-adjustment slide assembly250 includes a pair ofslide assemblies250A and250B that are fixedly mounted on thepad210. The width-adjustment slide assembly250 includes a width-adjustment rail256 with alatch mechanism260. One embodiment of thelatch mechanism260, shown inFIGS. 4A and 4B, comprises a latch262 that is captured in alatch bracket264. Thelatch bracket264 has a series of notches and the latch262 is a spring pawl262A that catches in one of the notches. Applying force to the latch262 depresses the spring pawl262A and releases it from a latched position. An ideal pressure point is identified in the embodiment shown with a visual andtactile cue266. When thelatch mechanism260 is depressed, the width-adjustment rail256 may be slid to another position in thelatch bracket264. In this way, the width of the height-and-width adjustingframe220 is adjusted to accommodate the width of a computer to be stored in theuniversal computer case1000. In the particular embodiment shown, thepad210 is supported on pad supports212, best seen inFIG. 2, that serve to raise the lower surface of thepad210 slightly above the surface of thelower lid120 to provide the necessary space to accommodate a pull-out handle (not shown) that is slidably recessed into the case. In cases without the pull-out handle, it may still be desirable to raise thepad210 above the surface of thelower lid120 to provide space for the spring pawl262A, although raising thepad210 is not a limiting feature of the invention.
The height-adjustment slide assembly230 includes height-adjustment rails234 that are slidably captured in a height-adjustment slide assembly236, which is affixed to the width-adjustment rail256 at junction237. The height-adjustment slide assembly236 comprises a latch assembly238 that includes the same latch mechanism as described above, that is, it has a latch262 and a spring pawl262A that catches in alatch bracket264. In the embodiment shown, the height-adjustment slide assembly236 is a double-ended bracket, each end containing thelatch bracket264. The outer ends of the height-adjustment rails234 are formed ascorner retainers232 for receiving the corners of the computer to be stored in theuniversal computer case1000. The overall height of theframe220 is adjustable by depressing the latch262 and sliding the height-adjustment rail234 at one or both ends of the height-adjustment slide assembly230 to the desired position. An intermediate portion of the height-adjustment slide assembly236 connects to anouter end259 of the width-adjustment rail256.
FIGS. 5,6, and7 illustrate thepress device300, which is used to apply a shock-absorbing pressure to the computer when theuniversal computer case1000 is closed, to prevent the computer from rattling or bumping in the case. The figures show the press device, isolated from theuniversal computer case1000, for purposes of illustration. Thepress device300 is a clamshell device having a mountingpanel302 and apress slide310 mounted on aslide track320. The mountingpanel302 andpress slide310 are coupled to each other by means of ahinge304.
FIG. 8 is a cross-sectional view of theupper lid130 and illustrates the function of thepress device300. The mountingpanel302 is affixed to the inner surface of theupper lid130, preferably where anupper lid wall130A and anupper lid sidewall130B come together. A biasing spring forces theslide track320 upwards toward the mountingpanel302. Theslide track320 is in a raised position when thepress slide310 positioned at afirst end320A of theslide track320. By raised position is meant, that thepress slide310 is in its uppermost position, relative to thebase plate200. Moving thepress slide310 up toward asecond end320B of theslide track320 forces theslide track320 into a steeper downward slant, to a pressure position. The undersurface of theslide track320 has abuffer pad330, which is preferably a shock-absorbing foam material that is adhesively affixed to the slide track. When in the pressure position, thebuffer pad330 presses against the computer stored in theuniversal computer case1000. This prevents the laptop from rattling in the case and also serves to absorb impact forces.
It is understood that the scope of protection is not limited to certain types of materials used for the various features of theuniversal computer case1000. In a preferred embodiment, thelatch mechanism260 and height-adjustment slide assembly230 and width-adjustment slide assembly250 are made of metal or metal-coated hard plastic. Thepad210 is ideally made of a rigid plastic material, as are the upper and lower lids of thehard case100. Theuniversal computer case1000 may include additional features, such as recessible or pull-out handles, storage frames for storing CDs or memory sticks, etc., and padding on the inner surfaces of thehard case100.
It is understood that the embodiments described herein are merely illustrative of the present invention. Variations in the construction of the universal computer case may be contemplated by one skilled in the art without limiting the intended scope of the invention herein disclosed and as defined by the following claims.
