BACKGROUND OF THE INVENTION

Field of Invention

The disclosed subject matter is in the field of closure devices for connecting two or more parts together. In some specific instances, the disclosed subject matter is in the field of hubs and connectors for bags, backpacks, totes, briefcases, and the like.

BACKGROUND OF THE INVENTION

Tote bags and backpacks are well-known technologies for carrying personal objects. Typically, these bags and backpack are worn on a person's side or back. Usually, one or more load-bearing straps are supported on the person's shoulder.

Although suitable for carrying personal effects in many situations, known tote bags and backpacks are unsatisfactory in some circumstances. In particular, known backpacks and tote bags require that their load be born in a way that makes it difficult to quickly access the bag's or pack's contents. The load-bearing strap is often positioned so that a user must entirely take off the bag to access the contents. And, the need to remove the bag before accessing the bag's or pack's contents can leave the user vulnerable, e.g., to mugging if the user is in a dangerous or unfamiliar place. Prior art demands that both straps and the bag itself must be removed for an individual to access the contents of bag. Each step of this process is relatively time consuming and inefficient.

In view of the foregoing, a need exists for an improved load-balancing strap hub and connector for a bag or pack. Suitably, the improved load-bearing strap hub and connector for the bag or pack would involve redistributable forces applied to the connection. Such an improved load-bearing strap hub and connector would enable the contents of a bag to be quickly accessed with little sight or excessive mental input.

SUMMARY OF THE INVENTION

In view of the foregoing, an object of this specification is to disclose an improved load-balancing strap hub and connector for a bag or pack. Suitably, the improved load-bearing strap hub and connector for the bag or pack would involve redistributable forces applied to the connection. Such an improved load-bearing strap hub and connector would enable the contents of a bag to be quickly accessed with little sight or excessive mental input.

Of course, the disclosed closure devices could be used in other situations besides tote bags and backpacks. For instance, the closure device disclosed here could be used for belt buckling or webbing, chin straps for helmets, construction tiedowns, seatbelts, or any other analogous use. The analogous uses will be appreciated by those of skill in the art.

The subject matter disclosed may thus be generalized as being directed to a method of establishing a three point harness comprising the step of:

• • a. Identifying a load bearing strap, rope or webbing defined by hub that is connected to a first strip section on a side of a spoke and a second strip section connected on another side of the spoke;
  • b. Identifying a connector that is coupled to a third strip section, wherein the third strip section is not load-bearing;
  • c. Threading a post of the hub into a key hole of the connector;
  • d. Sliding the post into a slot of the connector so that the connector is disposed between a head of the post and the spoke;
  • e. Rotating the connector around the post, the first strip section around a ring of the hub and the second strip section around the ring of the hub until each of the first strip section, the second strip section, and third strip section become loadbearing.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS

Disclosed is an improved load-balancing strap hub and connector for a bag or pack. Suitably, the hub features a post that is configured for mating with a slot of the connector. In use, the hub and connector may be used to redistribute load bearing forces of a bag or pack worn by a user. The more specific aspects of the disclosed hub and connector are described with reference to the drawings.

FIG. 1 is a perspective view of a hub 1000. FIG. 2 is a side view of the hub 1000. FIG. 3 is another perspective view of the hub 1000. As shown, the hub 1000 is defined by a ring 1100, two spokes 1110, and a coaxial post 1120 with a head 1121.

The ring 1100 is best seen in FIGS. 1 and 3. Suitably, the ring 1100 is annular. As shown, the ring 1100 has two spokes 1120 that diametrically bisect the ring 1100 structure.

The coaxial post is best seen in FIGS. 2 and 3. As shown, the post is coaxially positioned between the spokes 1110. The post 1120 is cylindrical. Suitably, the post 1120 features a cylindrical head 1121 that is disposed at the proximal end of the post 1120 and that is larger in diameter than the post 1120.

FIG. 4 is a perspective view of a connector. FIG. 5 is a plan view of the connector. As shown, the connector 2000 is defined by a base 2100 with keyhole 2110 and slot 2120. The base 2100 also features a strap hole 2200.

FIG. 6 is a top view of a hub and connector in a first configuration. As shown, the first configuration is accomplished via threading the head 1121 and post 1120 of the hub 1000 through the key hole 2110 of the connector 2000. By design the coupling of these two elements is more streamline than prior art. This leads bag access to become substantially easier. The ease of access is due to the fact that an individual is able to access the contents of their bag in less steps. Prior art such as a backpack demands that both straps and the bag itself must come off when accessing bag contents. The invention allows an individual to access bag contents by simply decoupling one strap from the hub, then slide the bag from an individual's back to the individuals chest, all while keeping their bag on. FIG. 7 is a perspective view of the hub and connector in the first configuration. FIG. 8 is a side view of the hub and connector in the first configuration. FIG. 9 is a perspective view of the hub and connector in the first configuration. FIG. 10 is a bottom view of the hub and connector in the first configuration.

FIG. 11 is a top view of the hub and connector in the second configuration. As shown, the second configuration is accomplished in one step from the first configuration of FIGS. 6 through 10 by sliding the post 1120 of the hub 1000 into the slot 2120 of the connector 2000 so that the base 2100 is disposed between the head 1121 and spokes 1110 of the hub 1000. FIG. 12 is a perspective view of the hub and connector in a second configuration. FIG. 13 is a side view of the hub and connector in the second configuration. FIG. 14 is a perspective view of the hub and connector in a second configuration. FIG. 15 is a bottom view of the hub and connector in the second configuration.

FIG. 16 is an environmental view of the hub and connector in the first configuration. FIG. 17 is another environmental view of the hub and connector in the second configuration. As shown, a first strap 3100 may be secured to the ring on one side of the spokes 1110 while a second strap may be secured to the ring on the other side of the spokes 1110. A third strap 3300 may be secured to the strap hole 2200 of the connector 2000. As shown, the second configuration of FIG. 17 is accomplished in one step from the first configuration of FIG. 16 by sliding the post 1120 of the hub 1000 into the slot 2120 of the connector 2000 so that the base 2100 is disposed between the head 1121 and spokes 1110 of the hub 1000. FIG. 18A is yet another environmental view of the hub and connector in a third configuration. Suitably, the third configuration may be accomplished via rotating the connector 2100 around the post 1120 while the post is disposed in the slot 2200.

FIG. 18B is a demonstrative view of the hub and connector. As discussed below, the hub 1000 and connector 2000 may be a load-balancing hub and connector with redistributable forces applied to the established connection. Suitably, a load (shown in empty arrows in FIG. 18 B) may be redistributed in any radial direction around the ring 2100 via moving the straps 3100 and 3200 around the ring (e.g., in the solid arrow direction) and rotating the connector 2000 around the post 1120.

FIG. 19 is a perspective view of an alternate embodiment of a hub. FIG. 20 is a side view of the alternate embodiment of a hub. FIG. 21 is a perspective view of the alternate embodiment of a hub. As shown, the alternate embodiment of the hub is substantially similar to the earlier described embodiment of a hub 1000. Suitably, the alternate embodiment of the hub has two coaxial posts instead of just one coaxial post like the earlier described hub 1000.

FIG. 22 is an environmental view of the alternate embodiment of a hub and the connector. As shown, two different connectors can be coupled to the alternate embodiment of the hub by providing the post of the alternate hub into the slot of a connector as described above. Suitably, the four straps connected by the hub and two connectors can redistribute load forces in any radial direction relative to the ring by rotating the straps around the ring or the connectors around the posts.

FIG. 23 is a perspective view of a tote bag with straps that involve the hub and connector. FIG. 24 is another perspective view of the tote bag with straps that involve the hub and connector. FIG. 25 is a front view of the tote bag with straps that involve the hub and connector. FIG. 26A is rear view of the tote bag with straps that involve the hub and connector. FIG. 27 is rear view of the tote bag with straps that involve the hub and connector. As shown, the tote bag may be worn over the shoulder.

FIG. 27A is an environmental view of a tote bag with straps that involve the hub and connector. FIG. 27B is a zoomed-in environmental view of the tote bag shown in FIG. 27A. As shown, the bag may be provided over the shoulder of a person 4000 and the connector 2000 coupled to the hub to create a three point harness. In use, coupling the connector 2000 to the hub 1000 translates the shoulder strap and an additional strap into a three point harness that is configured to hold the bag 3000 close to the body 4000 in a controlled fashion (this is best for use case for activity, cycling etc). The custom fastener directs the end of the straps over the center of the chest, which allows for a neutral feel because the distribution of forces is at/near the users center of gravity. In addition the forces the straps exert on each other counter act each other. Suitably, coupling the straps via the hub and connector creates a back pack from a tote bag.

Referring to FIGS. 23 through 27B, a method of establishing a three point harness is disclosed. Referring to FIGS. 23 through 26, a load bearing strap is defined by hub that is connected to a first ribbon on a side of a spoke and a second ribbon connected on another side of the spoke. Referring to the same figures, a connector is coupled to a third ribbon, wherein the third ribbon is not load-bearing. Referring now to FIGS. 27A and 27B, a post of the hub may be threaded into a key hole of the connector. Next, the post may be slid into a slot of the connector so that the connector is disposed between a head of the post and the spoke (as shown). Finally, the connector may be pivoted around the post, the first ribbon rotated around a ring of the hub and the second ribbon rotated around the ring of the hub until each of the first ribbon, the second ribbon, and third ribbon become loadbearing.

FIG. 26B is rear view of the tote bag with straps that involve the hub and connector. As shown, the bag 3000 is intended for ambidextrous use by alternating the side affixed to the third strap or ribbon. When attached on the left side, set up for right handed users or on the right side for left handed users. In some cases the strap may be clipped in place.

FIG. 28 is a perspective view of an alternate embodiment of a connector. FIG. 29 is a top view of the alternate embodiment of the connector of FIG. 18. As shown, the connector of FIGS. 28 and 29 feature a lock for preventing disconnection of the connector and hub.

FIG. 30 shows the range of motion of the straps 3100 and 3200 that are threaded through the hub 1000.

FIG. 31 shows the rotational range of motion of the connector 2000.

FIG. 32 shows the rotational range of motion of two connectors 2000 coupled with an alternative embodiment of a hub 1000.

FIG. 33 shows a coupled hub 1000 and a connector 2000. FIG. 33a shows a sectional view of the coupled elements. The hub and connector feature 45 degree chamfers to accept the connector fitting into the hub.

This same feature is useful in decoupling the hub and connector without obstacle. FIG. 33b shows another sectional view of the coupled elements The hub and connector are faced to feature parallel faces to prevent accidental decoupling of the two elements.
