Customizable bag with retractable strap
View Patent ↗The present disclosure provides for a bag with a retractable strap and different variations of accessory panels located throughout the bag. In some aspects, the retractable strap may be moved into different orientations on the bag rather than a stagnant placement throughout the use of the bag. In some embodiments, the bag may have several interior and exterior accessory panels that allow for limitless combinations of accessories to be added for maximum customization from bag to bag. In some implementations, the bag and frame may be made up of different materials depending on the intended use of the bag. In some embodiments, the retractable strap may have different length control mechanisms, allowing the strap to be retractable no matter the orientation. In some implementations, the retractable strap may extend via a constant force spring. In some aspects, the rotational force of the extension of the constant force spring may provide a constant force.
1. A bag with retractable strap, the bag comprising:
a frame comprising:
a center frame comprising four connected rigid walls,
an inner frame comprising four connected rigid walls configured to attach to at least a portion of the center frame; and
an outer frame comprising at least two rigid walls configured to attach to at least a portion of the center frame, wherein the center frame is configured between the inner frame and the outer frame;
a retractable strap comprising a first end and a second end;
an outer material configured to cover a portion of the retractable strap and a portion of the outer frame, wherein the outer material and the outer frame comprise a first strap opening and a second strap opening;
an inner material covering the center frame, wherein the inner material is configured to form an interior containing recess of the bag;
an outer panel configured to be partially detachable to allow access to the interior containing recess;
a set of constant force springs configured to control a set of positions of the retractable strap, wherein a first constant force spring is connected to the first end and a second constant force spring is connected to the second end; and
a set of frame mounts configured to mount the set of constant force springs to the center frame, wherein a first frame mount mounts the first constant force spring to the center frame and a second frame mount mounts the second constant force spring to the center frame, wherein, when mounted, the retractable strap extends through the first strap opening and the second strap opening allowing for access to the retractable strap, and wherein, when mounted, each constant force spring is enclosed by the outer frame.
2. The bag of claim 1 , wherein the bag comprises a backpack.
3. The bag of claim 1 , wherein the bag comprises a laptop bag.
4. The bag of claim 1 , wherein one or both the outer panel and the inner material comprises a modular pocket system.
5. The bag of claim 1 , wherein the retractable strap comprises a flexible material.
6. A retractable strap mechanism for bag, the retractable strap mechanism comprising:
a frame comprising:
a center frame comprising four connected rigid walls,
an inner frame comprising four connected rigid walls configured to attach to at least a portion of the center frame, and
an outer frame comprising at least two rigid walls configured to attach to at least a portion of the center frame, wherein the outer frame comprises a first strap opening and an second strap opening, wherein the center frame is configured between the inner frame and the outer frame;
a retractable strap comprising a first end and a second end;
a set of constant force springs configured to control a set of positions of the retractable strap, wherein a first constant force spring is connected to the first end and a second constant force spring is connected to the second end; and
a set of frame mounts configured to mount the set of constant force springs to the center frame, wherein a first frame mount mounts the first constant force spring to the center frame and a second frame mount mounts the second constant force spring to the center frame, and wherein, when mounted, the retractable strap extends through the first strap opening and the second strap opening allowing for access to the retractable strap, and wherein, when mounted, each constant force spring is enclosed by the outer frame.
7. The retractable strap mechanism of claim 6 , wherein the retractable strap comprises a flexible material.
8. The retractable strap mechanism of claim 6 , wherein the bag comprises a backpack.
9. The retractable strap mechanism of claim 6 , wherein the set of constant force springs extends via rotational extension.
10. The retractable strap mechanism of claim 9 , wherein the set of constant force springs transfers rotational retention force to a linear force exerted on the retractable strap mechanism.
11. The retractable strap mechanism of claim 10 , wherein the force exerted by the set of constant force springs on the retractable strap mechanism is maintainable in a modified level of constant force by an external force exerted on the set of constant force springs.
