Abstract

The inventive subject matter is generally directed to a pack with an automatically opening compartment. The pack has a body that defines a volume for the containment of articles, and a strap system for supporting the pack in a user's body. A section of the pack is hingeably coupled to another body portion of the pack. The hingeable section has a first condition, providing an opening to a compartment in the pack, and a second condition, closing the opening to the compartment. The hingeable section is coupled to a spring system that is (1) unloaded when the hingeable section is in the first condition and (2) relatively loaded when in the second condition, so that the compartment automatically opens when the closure system is released. The pack may include a closure system for locking the hingeable section in the closed condition.

First claim

The inventors reserve all rights to the subject matter disclosed herein, including the right to claim all that comes within the scope and spirit of the following claims:

1. A backpack, comprising:
a body defining a volume for the containment of articles, the body generally having a front surface and an opposing back surface, opposing side surfaces, and opposing top and bottom surfaces, the surfaces being arranged to define a compartment of a backpack;
the front surface having upper and lower portions, the upper portion comprising a hingeable section hingeably coupled to the lower portion, the hingeable section having a first condition providing an opening to the compartment in the pack and a second condition closing the opening to the compartment, wherein the front portion is movable relative to the back portion by the front portion's hinging along a joint that is defined by (1) a lower end of the hingeable section and (2) the top end of the lower portion of the front surface;
a closure system for locking the hingeable section in the closed condition;
wherein the hingeable section being coupled to a spring system that is unloaded when the hingeable section is in the first condition and relatively loaded when in the second condition, so that the compartment automatically opens when the closure system is released;

wherein the hingeable section includes a movable frame member that is pivotably connected to the body portion of the pack and coupled to the spring system; and
wherein the movable frame member comprises a generally U-Shape, the closed end of the U-shaped frame member being coupled to the hingeably section at a top edge and having downwardly extending legs that pivotably couple with opposite sides of a body portion of the pack.

2. The pack of claim 1 wherein the hingeable section comprises a pliable material.

3. The pack of claim 2 wherein the hingeable section hinges at a joint comprising a flexure bearing or living hinge formable in the pliable material.

4. The pack of claim 3 wherein the joint is formed of a material that is more flexible or thinner than a body portion of the pack adjacent the joint off of which the hingeable section hinges.

5. The pack of claim 1 wherein the spring system is pivotably coupled to at least one leg of the frame member.

6. The pack of claim 1 wherein the spring system comprises a mechanical spring.

7. The pack of claim 1 wherein the spring system comprises a torsion spring.

8. The pack of claim 1 wherein the spring system comprises a materials-based spring.

9. The pack of claim 1 wherein the hingeable section is disposed at an upper front portion of the pack.

10. The pack of claim 1 wherein the opening is for a main compartment of the pack.

11. The pack of claim 1 wherein the opening is for a compartment of the pack sufficiently sized and shaped to hold a laptop or tablet computer having dimensions of at least 20 cm by 12 cm.
