The present invention relates generally to carrying cases or bags, for safely transporting delicate instruments, such as computers, and more particularly to impact resistant cushions for use in carrying cases.
Laptop computers vary widely in size and shape, depending on the features engineered into them by their manufacturers. This variation makes it difficult for carrying case manufacturers to design cases which offer adequate protection against accidental drops, yet still fit the wide variety of laptops available.
Most laptop cases have foam padding surrounding the internal cavity, which holds the laptop. The cavity is sized to fit a certain range of different-sized laptops, but it never perfectly matches all laptops. Invariably, there is some room left within the carrying case, such that the laptop is susceptible to damaging impact in the event of an accidental drop.
A common approach to addressing the above problem is disclosed in U.S. Pat. No. 5,960,952, wherein a laptop is strapped into a briefcase and a single moveable foam bar is used to separate the laptop from its associated accessories. The foam bar is not held firmly in place and offers little protection in the event of a fall. Also, since the laptop is not centered in the case, weight distribution is uneven, making it somewhat awkward to carry.
An improvement is disclosed in U.S. Pat. No. 6,334,533, wherein two adjustable cushion segments are described, one of which can be positioned laterally to change the internal width of the case to fit the width of the laptop. However, the laptop is still off-center and the height of the internal case cavity is not adjustable.
U.S. Pat. No. 5,857,568 discloses another solution, whereby an adjustable frame is used to re-size the inside of the case to match the size and shape of the laptop. The laptop remains centered, ensuring even weight distribution. While this invention does address the problems identified above, it is mechanically complicated. The user of this case would need tools to configure it properly, and the additional weight of the frame places an undue burden on the user who is already encumbered by the weight of the laptop.
U.S. Pat. No. 5,769,232 describes an inflatable protective lining system for shipping containers. Depending on the degree of inflation, the lining can be adjusted to hold the enclosed article suspended within the container.
According to the present invention, an adjustable cushioning system is provided for use in a carrying case or the like, adapted to be re-sized internally to match the size and shape of its contents. Shock-absorbent spacers are stacked against the walls of the case or bag to adjust the internal dimensions of the case or bag as desired.
A detailed description of the invention is set forth herein below, with reference to the following drawings, in which:
As used herein, “carrying case” means any case or bag for carrying fragile items such as laptop computers, whether such case or bag has soft or rigid exterior walls.
As shown in
By varying the number of spacers, the user can adjust the internal dimensions to snugly fit any size of laptop that is not larger than the case or bag itself. No tools are required to perform this adjustment. The spacers can be pulled apart with only a slight effort.
As shown in
With reference to
A person understanding the present invention may conceive of other embodiments or variations, all of which are believed to be within the sphere and scope of the invention as defined by the claims appended hereto.
