Laptop computer case and spring protection system
View Patent ↗A lightweight computer carrying case ( 1 ) has an undulating leaf spring ( 17 ) enclosed between two layers of foam. The foam strips and leaf spring are bonded to one another, and the combined spring protection system ( 15 ) is surrounded by an aesthetic layer of fabric and mounted in the interior of a main packing compartment. Once snugly fitted betwixt the spring protection device, the computer ( 23 ) is strapped in and enjoys superior safety from impact forces, including impacts felt on the corner of the carrying case. The foam is of EVA construction and the leaf spring comprises polypropylene or ABS. A unique and aesthetically pleasing outer pocket with a curving zippered access ( 29 ) holds valuables, and a sleeve pocket on the outer front face of the case provides easy access to computer peripherals and such.

3. The carrying case of claim 1 wherein the spring is a single continuous resilient piece.
4. The carrying case of claim 1 wherein the spring comprises a leaf spring.
5. The carrying case of claim 1 wherein the foam comprises two continuous layers, and said spring is sandwiched between the two continuous layers of foam.
6. The carrying case of claim 1 wherein the spring and the foam are removable from the main packing compartment.
7. The carrying case of claim 1 wherein the undulations of the spring protrude outwardly at corners of the main packing compartment to provide additional shock absorption.
8. The carrying case of claim 1 wherein the spring comprises six undulations along an interior edge of the main packing compartment.
9. The carrying case of claim 1 wherein the spring comprises five undulations along an interior edge of the main packing compartment.
10. The carrying case of claim 1 wherein the foam is comprised of ethylene vinyl acetate.
11. The carrying case of claim 1 wherein the foam is comprised of two layers of foam each with a thickness of between 3 mm and 15 mm.
12. The carrying case of claim 1 wherein the spring is comprised of a polymer selected from a group including polypropylene, polyethylene or acrylonitrile butadiene styrene.
13. The carrying case of claim 1 wherein the spring includes a thickness of between 0.5 mm and 6 mm.
14. The carrying case of claim 1 wherein the spring and the foam are surrounded by a fabric envelope.
15. The carrying case of claim 14 wherein the fabric envelope, the spring and the foam are simultaneously and readily removable from the carrying case.
16. The carrying case of claim 1 wherein the spring and the foam are formed to define a shape that generally conforms to the shape of the laptop computer carried therein.
17. The carrying case of claim 1 wherein the spring and the foam are sized to provide a substantially tight fit around the peripheral of the laptop computer carried therein.
18. The carrying case of claim 1 wherein the spring includes top, bottom, right and left sides that generally define a rectangle, and at corner portions of the spring, the undulations of the spring that are located on the top and bottom sides of the spring almost touch the undulations of the spring that are located on the left and right sides of the spring.
19. The carrying case of claim 18 wherein the spring is continuous at the corner portions of the rectangle.
20. The carrying case of claim 18 wherein each of the top, bottom, left and right sides of the spring comprises a width dimension perpendicular to the undulations of the spring, and at least one of the width dimensions is different from at least one of the other width dimensions.
21. The carrying case of claim 1 wherein the spring forms a continuous closed loop.
22. The carrying case of claim 1 wherein the foam forms a continuous closed loop.
23. The carrying case of claim 1 wherein the spring and the foam are configured to form at least one undulation at a corner of the main packing compartment, the at least one undulation comprises a first portion and a second portion that define an outwardly protruding structure, and sections of the first and second portions of the at least one undulation almost touch each other.
24. The carrying case of claim 23 when an item is received within the main packing compartment, the at least one undulation touches two different sides of the item received within the main packing compartment.
25. The carrying case of claim 24 wherein the two different sides of the item received within the main packing compartment converge to form a corner, and the at least one undulation provides a substantially tight fit around the corner of the item received within the main packing compartment.
