Backpack for Carrying a Laptop Computer

The present invention relates to a backpack for use in storing and carrying a laptop computer.

Laptop computers have become quite common for business, school and personal uses in recent years. With the portability of the laptop computer, there is a need for a convenient and secure carrying case such as a backpack for carrying such laptop computers. Conventionally, laptop computer carrying cases have been in the form of carrying cases which resemble small suitcases. In those cases where backpacks have been adapted to carry laptop computers, the loading and unloading of the laptop computer with respect to the opening of backpack has proven to be highly inconvenient. For example, the backpack generally provides a small opening where the user must get the computer into the backpack through a small opening or the backpack is opened along three sides so that the backpack opens at a 180.degree. angle, a more convenient and efficient configuration would be somewhere between the extremes.

Accordingly, there is a need for a backpack constructed so as to provide a more convenient and efficient loading and unloading of a laptop computer into a backpack.

In accordance with the present invention, there is provided a backpack for carrying laptop computers comprising a main compartment for receiving the laptop computer having flexible front, rear and bottom panels and a flexible side panel joined to said front, rear and bottom panels along the perimeters thereof to generally define the shape and size of the backpack and, more particularly the interior of the backpack. The front and rear panels are hinged along an axis of the bottom panel of the backpack intermediate the bottom longitudinal edges of the front and rear panels and is openable along the top and side panels intermediate to and parallel with the top and side edges of the front and rear panels by a closure means, preferably a zipper, which extends longitudinally along the side wall to control access to the interior of the compartment. In order to prevent the front and rear panels from opening completely so that they do not lie flat with their outer surface in a plane, i.e., 180.degree. the backpack is provided with at least one adjustable interlocking assembly on each side of the backpack to restrict and maintain a predetermined interval of pivotal separation of the front and rear panels to allow convenient and easy access to the compartment interior. The backpack is provided with a pair of adjustable shoulder straps so that the backpack can be carried in a conventional manner on a user's back. The backpack is also provided with a pair of pliable handles at the top of the backpack so that it can be transported by using the handles rather than the shoulder straps if desired, in which case, the shoulder straps can be stored out of sight in a storage pocket on the rear of the backpack. The handles, as mentioned, are formed from a flexible material and can be releasably joined to each other in a conventional manner.

The interlocking assembly 26 includes any easily releasable locking device 28 such as a buckle, spring clip and O- or D-ring fasteners, hook and loop fasteners, and the like. Alternatively, the interlocking device may simply be an adjustable strap. Preferably, the interlocking device is a buckle. The interlocking assembly 26 also includes a means for adjusting the interlocking assembly 26, preferably by at least one adjustable strap 30 wherein the strap is adjusted by any adjustable means, for example, by looping the strap through a multiple apertured lock. Other adjustable means may be employed such as a hook and loop device, snaps, or by tying such as with a cord. In accordance with the invention, the adjustable interlocking assembly 26 is useful for restricting the pivotal separation of the opening of the backpack 10 when the closure means 22 is open.

The compartment 14 includes a flexible restraint which comprises a first flexible fabric strap 38 preferably padded with a foam material which is joined to and extends laterally across the inner surface generally designated as 40, of the rear panel 18. Typically, the rear panel 18 and the side panel 20 adjacent the laptop computer contains a foam material between the inner and outer surfaces of the panels as a safety measure to prevent impact damage to the laptop computer 12 if accidently dropped or otherwise mishandled. The flexible restraint further comprises a second flexible strap 42 one edge of which is joined to the inner surface of the bottom panel 32 and extends across the laptop computer 12 vertically with respect to the first flexible strap. The first flexible strap 38 folds down across one end of the laptop computer 12. Typically, the bottom end, and the second flexible strap 42, extending across the laptop computer 12 from the bottom of the compartment 14, releasably interlocks with the first flexible strap 38, centrally with respect to the sides of the compartment to secure the laptop computer 12 in the compartment 14. In the upper region of the compartment 14 adjacent the inner surface of the rear panel 18, there is typically provided a pair of elastic straps 46 for storing various accessories.

The backpack 10 of the present invention contains a storage pocket 52 on the rear panel 18, and a pair of adjustable shoulder straps 48 connected to the rear panel 18 of the backpack 10. In a preferred aspect, the shoulder straps 48 are attached to the backpack by stitching along a seam 50 joining the back panel 18 and the top of side panel 20 and releasably attached a buckle or other such means on opposite sides of the backpack 10 along the seams joining the side panel 20 and the rear panel 18 in the lower half of the backpack 10.
