SUMMARY OF THE INVENTION
The following presents a simplified suminary of some embodiments of the invention in order to provide a basic understanding of the invention. This suanrnary is not an extensive overview of the invention. It is not intended to identify key/critical elements of the invention or to delineate the scope of the invention. Its sole purpose is to present some embodiments of the invention in a simplified fon-n as a prelude to the more detailed description of some embodiments that are presented later.
In accordance with an embodiment, a suspension system for adjusting the position of shoulder straps on a backpack is provided. The suspension system (shoulder strap adjust:rnent mechanism) includes a hub that is attached to the sack for the backpack, an.d a yoke that is attached to the hub and is movable up and down with respect to the hub. The yoke is attached to shoulder straps for the backpack. Moving the yoke allows the backpack, and specifically the distance from the waist belt to the shoulder straps, to be adjusted to a particular user.
Docket No, Orgpls-2-5871 In an embodiment, the hub includes a back panel that is inserted in a back pocket of a sack for the backpack. The back panel may alternatively be encased within the backpack sack, or partially encased within the backpack sack. The panel may also be sewn to thc backpack sack. The yoke may be partially or fully included within the sack, wherein the shoulder straps extend from the yoke out of the sack.
The hub may include removable and/or interchangeable stays that attach the hub to the backpack sack and/or a waist belt for the baclcpack. A
central stay may be provided that extends from a bottom of the hub to a location on the belt, thereby providing a central point of stability for the backpack.
In an embodiment, the yoke is attached to a slider that moves along a structure, such as a center channel, in the backpack. The slider is releasably lockable in multiple different locations. In an embodiment, the slider includes a rocker latch that locks to teeth in the center channel. A user may simply release the rocker latch, for exainple against the bias of a spring, to allow movement of the slider along the center channel. The slider may then be locked back in place by allowing the rocker latch to engage a different set of teeth along the center channel.
The releasable lock for maintaining the slider in position may include a strap or other structure that allows access to and release of the releasable lock, especially where the releasable lock may be hard to reach. For example, if the slider and the releasable lock are mounted inside a sack for backpack, then the strap may pennit release of the releasable lock without having to access the inside of the backpack sack. In addition, a strap may be of sufficient length so Docket No. Orgpls-2-5871 that a user may adjust the releasable lock while the baclcpack is on the user's back.

To provide for adjushnent of the shoulder straps, a yoke 28 is slidably attached to baclc panel 26, where the shoulder straps (not shown, but known) are connected to the yoke 28. Briefly described, the slidable attachment of the yoke 28 to the back panel 26 permits the attachment of the shoulder straps to the backpack 20 to be easily and quickly adjusted along the vertical, longitudinal, length of the back panel 26.
Referring to FIGS. 2 and 4, a center guide channel 46 is provided partially along the longitudinal lengtll of the back panel 26. A slider 48 is mounted within the center channel 48, where the slider 48 can be sliding moved along the leiigtla of the center channel 46 for sliding movement along the center channel 46.
Referring also to FIG. 5, the center channel 46 includes a back 50 which is adjacent to, or is formed as part of, a portion of the back pane126.
An annular rim 52 is positioned around a top edge of the center channel 46.
Angled teetb 54 are located at a bottom portion of the center channel 46( see also FIG. 6).
As shown in FIG. 7, the slider 48 includes a lower plate 58 sized to fit between the annular i-im. 52 and the back 50. In this manner, when the slider 48 moves along the center channel 46, the lower plate 58 slides between the annular rim 52 and the back 50. The slider 48 includes a post 60 extending upwardl.y there from.
The longitudinal position of the slider 48 within the center channel 46 can be locked with a locking mechanism. Referring again to FIG. 5, a locking mechanism can include a rocker latch 62. An upper poz-tion of the rocker latch Docket No. Orgpis-2-5871 62 is pivotally mounted to tl-xe slider 48 with a rocker axle 66, where the rocker latch 62 is pivotable about the rocker axle 66. An. opposite end of the rocker latch 62 can include a pair of oppositely extending protrusions 64 extending outwardly from opposite sides of the rocker latch 62.
Each of the protrusions 64 on the rocker latch 62 is configured to fit within slots 55 formed between adjacent pairs (on the same side of the center channel 46) of angled teeth 54. In this manner, the protrusion. 64 fit within opposite slot pairs 55 located on opposite sides of the center chanael 46 when the rocker latch 62 is in a down, locked, position. In the locked position, the proti usions 64 are position inside the slots 55, toward the inside of the center channel 46. The engagenaen.t of the protrusions 64 within slots 55, between adjacent angled teeth 54, secures the position of the slider 48 within the center channcl 46.
A bias member can be provided on the rocker latch 62, where the bias member biases the rocker latch 62 in a down, locked, position. A spring may be positioned, for example, about the rocker axle 66. The bias member biases the protrusions 64 into the slots 55 foi-med between adjacent pairs of angled teeth 54. The rocker latch 62 thus prevents movement of the slider 48 along the longitudinal length of the center channel 46.
A strap loop 68 can be positioned between the two protrusions 64. A
strap 70 (FIG. 1) may be attached to the strap loop 68. The strap 70 provides a handle for inovement of the rocker latch 62. For exainpla, a user may pull outward on the strap 70 to move the rocker latch 62 between and open and locked position.
To provide for adjushnent of the shoulder straps, a yoke 28 is slidably attached to baclc panel 26, where the shoulder straps (not shown, but known) are connected to the yoke 28. Briefly described, the slidable attachment of the yoke 28 to the back panel 26 permits the attachment of the shoulder straps to the backpack 20 to be easily and quickly adjusted along the vertical, longitudinal, length of the back panel 26.
Referring to FIGS. 2 and 4, a center guide channel 46 is provided partially along the longitudinal lengtll of the back panel 26. A slider 48 is mounted within the center channel 48, where the slider 48 can be sliding moved along the leiigtla of the center channel 46 for sliding movement along the center channel 46.
Referring also to FIG. 5, the center channel 46 includes a back 50 which is adjacent to, or is formed as part of, a portion of the back pane126.
An annular rim 52 is positioned around a top edge of the center channel 46.
Angled teetb 54 are located at a bottom portion of the center channel 46( see also FIG. 6).
As shown in FIG. 7, the slider 48 includes a lower plate 58 sized to fit between the annular i-im. 52 and the back 50. In this manner, when the slider 48 moves along the center channel 46, the lower plate 58 slides between the annular rim 52 and the back 50. The slider 48 includes a post 60 extending upwardl.y there from.
The longitudinal position of the slider 48 within the center channel 46 can be locked with a locking mechanism. Referring again to FIG. 5, a locking mechanism can include a rocker latch 62. An upper poz-tion of the rocker latch Docket No. Orgpis-2-5871 62 is pivotally mounted to tl-xe slider 48 with a rocker axle 66, where the rocker latch 62 is pivotable about the rocker axle 66. An. opposite end of the rocker latch 62 can include a pair of oppositely extending protrusions 64 extending outwardly from opposite sides of the rocker latch 62.
Each of the protrusions 64 on the rocker latch 62 is configured to fit within slots 55 formed between adjacent pairs (on the same side of the center channel 46) of angled teeth 54. In this manner, the protrusion. 64 fit within opposite slot pairs 55 located on opposite sides of the center chanael 46 when the rocker latch 62 is in a down, locked, position. In the locked position, the proti usions 64 are position inside the slots 55, toward the inside of the center channel 46. The engagenaen.t of the protrusions 64 within slots 55, between adjacent angled teeth 54, secures the position of the slider 48 within the center channcl 46.
A bias member can be provided on the rocker latch 62, where the bias member biases the rocker latch 62 in a down, locked, position. A spring may be positioned, for example, about the rocker axle 66. The bias member biases the protrusions 64 into the slots 55 foi-med between adjacent pairs of angled teeth 54. The rocker latch 62 thus prevents movement of the slider 48 along the longitudinal length of the center channel 46.
A strap loop 68 can be positioned between the two protrusions 64. A
strap 70 (FIG. 1) may be attached to the strap loop 68. The strap 70 provides a handle for inovement of the rocker latch 62. For exainpla, a user may pull outward on the strap 70 to move the rocker latch 62 between and open and locked position.
Docket No. Orgpls-2-5871 In use, the protrusions 64 on the rocker latch 62 fit behind in the slots 55 between. pair of adjacent angled teeth 54. The spring biases the protrusions 64 into the slot 55. The rocker latch 62 thus prevents movement of the slider 48 along the center channel 46.
To release the lock provided by the rocker latch 62, a user 3nay pull on the strap 70, releasing the protrusions 64 from slot 55, permitting the slider to move freely along the center channel 46. During this movement, the lower plate 58 of the slider 48 moves along the groove formed between the annular riin 52 and the back 50 of the center channel 46. Then the slider 48 has been 1.0 moved to a desired position, the user may release the strap 70, causing the protrusions 64 to lock into and the slots 55 at that location..
Referring to FIGS. 1-3, the yoke 28 is attached to the post 60 of the slider 48. As such, when a user adjusts the position of the slider 48 within the center channel 46, the yoke 28 is simultaneously zza.oved. The yoke 28 can be triangular in shaped and have slots 72, 74, 76, 78 positioned at a top edge of the yoke 28. The two outer slots 72, 78 provide a first pair of slots for atiachment of shoulder straps, and the two itmer slots 74, 76 provide a second set of attachments for a set of shoulder straps. The outer slots 72, 78 may be utilized for a person having broader shoulders, and the inner slots 74, 76 may be utilized for a person having more narrow shoulders or desiring a different fit of shoulder straps.
To move the yoke 28, a user may pull outward on the strap 70 to move the rocker latch 62 between and open and locked position. The slider 48, and yoke 28, are moved along the center channel 46 to position the yoke 28 is a comfortable position for the user. Once the yoke 28 has been positioned, the Docket No. Orgpls-2-5871 user may release the strap 70, causing the protrusions 64 to lock into the slots 55. The movement of the yoke 28 provides simple relocation of the slots 72, 74, 76, 78 for shoulder straps so that the backpack 20 may be quickly and easily arranged to fit a particular user.
In am method of use, after shoulder straps are attached to a desired set of slots 72, 78 or 74, 76, the backpack 20 may be placed on the back of a user.
The strap 70 may be pulled to release the slider 48, and the yoke 28 inay be moved until the shoulder straps and the waist belt 30 are arranged in a comfortable manner on the user. The strap 70 is released, locking the position of the shoulder straps on the user.
In the embodiment shown in the drawings, the back panel 26 is bowed so as to contour to the back of multiple different users, and thus to move the yoke 28 along a contoured path so that the yoke 28 fits to a user's back despite its location along the center channel 46.
If desired, the strap 70 may be made longer so that it may extend to a location so that a user may easily grasp it and release the rocker latch 62 while the backpack 20 is on the user's back. In addition, in an embodiment, the rocker latch 62 may be encased inside the pocket 44 and/or the sack 22. In such an embodiment, the strap 70 may be of sufficient length to extend outward and be grasped by a user.
In the embodiment shown in the drawings, the back panel 26 is positioned in a pocket 44 on the back of the sack 22. The yoke 28 is fully accessible outside of.the pocket 44. Alternatively, the back panel 26 or anotlier hub may be positioned fully inside or partially inside the sack 22.
In Docket No. Orgpls-2-5871 addition, the yoke 28 or a portion of the yoke 28 may be positioned in a pocket, such as the pocket 44, or a portion of the sack 22. In either event, shoulder straps that are attached to the yoke 28 extend outward from the sack 22 so that they may be placed on the shoulders of the backpacker, with the back of the backpacker against the back of the backpack 20.
The back pane126 may be formed, for example, of plastic, a composite material, or another suitable material. In an embodiment, the back panel 26 includes a number of openings to lighten the overall weight of the back panel 26. These openings may be provided in positions so that they do not reduce the overall stiffness of the back panel 26. The yoke 28 may also be made of plastic, a composite, or another suitable material.
In another embodiment, the adjustment mechanism can be used on light weight backpacks. Referring to FIGS. 8 and 9, a back panel 80 for a light weight backpack is provided. The back panel 80 includes a longitudinal channel 81 into which a center channel 82 is positioned.
