- a preferred embodiment of the present invention is a backpack that can be used in many different configurations and is adaptable to support numerous attachments and accessories so as to support, for example, a soldier for up to five days or more.
- the main pack body includes three compartments, namely one large main compartment and two sewn-on, secondary compartments (one upper, one lower) on the backside of the pack. Two detachable side pouches may be provided. Also, a detachable bottom compartment may be provided.
- the drawings illustrate a backpack 10 which is medium-sized and includes a main pack body 12.
- the main pack body 12 consists of 3 compartments--one large main compartment 20, and two sewn-on, secondary compartments (one upper 22, one lower 24) on the backside of the pack 10.
- the volume of the main pack body 12 is approximately 3100 cubic inches.
- the side pouches 14 are approximately 100 cubic inches each in volume.
- a detachable bottom pouch 16 ( Figs. 26-29 ) is larger in volume, approximately 400 cubic inches.
- Figures 1 and 2 are views of the pack 10 with various features and components labelled.
- the two detachable side pouches 14 are shown attached to the backpack 10.
- the larger detachable bottom pouch or bottom compartment 16 is shown in Figs. 26-29 .
- the pack 10 itself does not include an internal or external frame, but is compatible with existing external frames. Thus, the pack 10 can be used alone, or with an external frame.
- the main compartment 20 ( Figs 1-3 ) spans the entire height of the pack.
- the main compartment 20 includes, on its inside, a pocket 30 ( Fig. 3 ) on the front side 32 (user side) of the compartment.
- the pocket 30 runs the entire height of the main compartment 20 and is sized to fit a radio or M8 mortar base plate.
- the pocket 30 is open to the top and its contents are retained via a single, centrally located cinch strap 34.
- the main compartment 20 is closed from the environment by an integral spindrift collar 36 (a cover that can be shut with a drawstring), as well as by a separate detachable lid 40.
- Figures 4 and 5 show the pack lid 40.
- the detachable lid 40 is secured to the pack via four lid straps 42, 44 on the sides, and a strip of hook fastener tape 46 along the front (user side) edge and rear edge of the lid.
- the two rear lid straps 42 are located on the lid 40 itself, and engage rear lid buckle connectors 48 ( Fig. 2 ) on the pack; the two forward lid straps 44 are located on the pack, and engage connectors 50 ( Fig. 4 ) on the lid 40.
- the hook fastener strip 46 on the lid 40 interfaces with a matching loop strip sewn to the front 32 (user-facing) and rear panels 54 of the main compartment 20.
- the hook-and-loop connection allows the lid 40 to hinge forward when the four lid straps 42, 44 are released and the rear hook-and-loop connection is disengaged.
- the lid straps 42, 44 are adjustable at their buckle connections to accommodate different sizes of internal contents for the main compartment 20, while allowing the pack 10 to be cinched down to minimize (conform) its volume to its internal contents.
- the rear lid straps 42 are formed by shaped panels 56 ( Fig. 4 ) of material integral to the lid 40 that are sewn to webbing straps.
- the rear lid straps 42 connect to buckles 48 sewn to the side panels of the main compartment 20 just below the upper cinch straps 72.
- the forward lid straps 44 are made from webbing sewn directly to the side panels just below the upper cinch straps 72, and attach to the lid 40 via a buckle 50 sewn directly to the lid.
- the detachable pack lid 40 incorporates PALS [Pouch Attachment Ladder System] -compatible (or MOLLE-compatible) webbing 58 on its top, external surface to facilitate the attachment of accessories. Specifically, sufficient PALS webbing 58 is incorporated to enable the attachment of a hydration carrier.
- PALS Pouch Attachment Ladder System
- FIG. 5 is a view of the underside of the pack lid 40.
- the lid incorporates on its underside an integral pocket 60.
- the pocket 60 is substantially the same size as the lid 40, and has an opening along the front (user-side) edge that is closed via hook-and-loop tape 62.
- This pocket 60 can be used for storage of miscellaneous accessories.
- the pocket 60 can be filled with necessities and the lid used as an escape and evasion pack when the entire backpack 10 cannot be carried.
- the lid 40 incorporates overlapping flaps 64, 65 at the forward (user-side) sides of the lid that engage each other with hook-and-loop tape. These flaps 64, 65, when opened at least partially, accommodate the pass through of radio antennas or other accessories that may be contained within the main compartment 120. These flaps 64, 65 create the front corners of the lid 40, but can be disengaged to create a small gap or opening 66 in the front, outer corners of the lid.
- Figures 5 , 6, and 7 contain views of the front edge of the pack lid 40 with the overlapping flaps 64.
- Figure 6 shows the flaps 64, 65 in the closed orientation
- Figure 7 shows the flaps in the gap (open) orientation.
- the pack 10 can be used without the detachable lid 40.
- the pack 10 includes a large spindrift collar 36 ( Fig. 8 ) that is sewn to and closes off the main compartment 20.
- the spindrift collar 36 allows the main compartment 20 to be closed off via a drawstring 70 at the collar's upper perimeter.
- the spindrift collar 36 also maximizes the water resistance of the main compartment 20, as it leaves a minimal opening to the main compartment when cinched.
- the spindrift collar 36 extends approximately 7.5 inches above the top edge of the main compartment 20. The flexibility and length of the spindrift collar 36 allow the pack 10 to expand in volume above the main compartment 20, and to accommodate items that are taller/longer than the main compartment.
- the size of the main compartment 20 can also be adjusted horizontally (laterally) via upper and lower cinch straps 72, 74 ( Fig. 2 ) on either side of the pack. This allows the main compartment 20 to be cinched in a horizontal fashion to minimize (conform) its volume to its internal contents.
- the upper and lower cinch straps 72, 74 are also designed to enable the pack 10 to be mounted onto an external frame, and serve as the primary interface with the frame.

- the cinch straps 72, 74 are still usable in their primary cinch function when the pack 10 is attached to an external frame.
- the upper cinch strap 72 runs nearly horizontally slightly above the midline of the main compartment 20.
- the strap 72 anchors to a webbing strap via adjustable buckles 76 ( Fig. 10 ) on the back (rear-facing) panel of the main compartment 20 between the upper and lower secondary compartments 22, 24, at either end.
- the upper cinch strap 72 runs continuously from one side around the front (user-facing) panel of the pack 10 and back to the other side, connecting to the webbing strap via the adjustable anchor buckle 76.
- the lower cinch strap 74 ( Fig.
- the cinch straps 72, 74 can be tightened and the main compartment 20 compressed down to its contents by the user pulling forward (toward the front panel) on the length of free webbing strap. Conversely, the cinch straps 72, 74 can be loosened by rotating the forward edge of the appropriate buckle 76, 78 about the vertical axis toward the back, releasing the frictional lock action of the webbing adjuster and then pulling on the tensioned length of strap to relieve tension and create slack.
- the external side panels of the main compartment include webbing guides 80 ( Fig. 2 ) for the upper cinch strap 72, as well as PALS-compatible webbing 82--one row in the upper area of the side panel for small accessories, and four rows at the bottom of the side panel for attachment of the side pouches 14 or other PALS-compatible accessories.
- the PALS webbing 82 and the upper cinch strap webbing guide 80 are shown in Figures 1 and 2 .
- Figure 9 shows the bottom (ground-facing) panel 90 of the main compartment 20.

- the pack 10 includes a suspension system that includes two main components--a waist belt or load distribution belt 160 and a shoulder strap system 190.
- Figures 18 and 19 are front and back views of the waist belt 160.
- the waist belt 160 includes an internally-padded belt 161 with 2-inch wide webbing straps 162 extending from either end that connects with a buckle system 162, 164.
- the padding is provided on the portion of the belt 161 that sits on the user's back, and extends around to the hip area.
- the length of padding is approximately 30 inches.
- the profile and top and bottom edges of the waist belt 160 are contoured to provide maximum comfort for the user while maintaining compatibility with body armour.
- the webbing 162 passes through a 2-inch D-ring 168 on each side after passing through the adjustable buckle 162, 164.
- the D-rings 168 are sewn into the waist belt 160 near the end of the padded portion.
- the waist belt 160 attaches to the main pack body 12 by sliding laterally through the lower pocket 114 ( Fig. 10A ). Vertical (downward) loads are transmitted from the main pack 12 to the waist belt 160 and thereby to the wearer's waist and hips.
- the waist belt 10 incorporates a pair of diagonal reinforcing straps 170 ( Fig. 20 ) on either side in the hip area to help carry the vertical loads into the cantilevered portion of the waist belt in the hip area of the user, while minimizing twist in the waist belt.
- the straps 170 are sewn to the back (pack-facing) side of the waist belt 160 and are anchored adjacent to the point at which the waist belt is loaded by the pack or where the waist belt is connected to an external frame.
- the straps 170 begin at the top and bottom edges of the waist belt 160 and converge diagonally to the waist belt webbing anchor point and tightening D-ring 168.
- a 2-inch piece of webbing 172 reinforces the connection at one end and a 1-inch piece of webbing 174 reinforces the connection adjacent to the pack/frame attachment.
- the diagonal orientation of the straps 170 allows the top and bottom edges of the waist belt 160 to react well to vertical loads.
- typical waist belt designs are constructed with a webbing strap centrally-located on the waist belt. Such a centrally-located strap tends to deform and roll the waist belt over when the waist belt system is loaded.
- the diagonal straps 170 are pretensioned before being sewn to the waist belt 160. This pre-tensioning helps the waist belt 160 better react vertical waist belt loads by removing potential slack, and also forces the belt sides into an open configuration that is more easily donned.
- the waist belt 160 incorporates two shoulder strap D-ring connectors 176 ( Fig. 20 ).
- the shoulder strap D-ring connectors 176 are sewn near the vertical centreline of the waist belt 160.
- the waist belt incorporates two additional strap connectors 180 ( Fig. 19 ), one located on each side of the vertical centreline of the back (pack-facing) side.
- Each strap connector 180 includes a webbing loop and a webbing adjuster
- the pack 10 includes a shoulder strap system 190 that connects directly to the waist belt 160 instead of directly connecting to the main pack body 12.
- Figures 21 and 22 are front and back views of the shoulder strap system 190.
- Figure 23 is a view of the pack 10 with the shoulder strap suspension system 190 directly attached.
- the shoulder strap system 190 includes a padded central support 192 and two padded shoulder straps 194.
- the central support 192 is designed to sit directly on the user's back, inside the pack itself.
- the central support 192 incorporates four webbing straps 196 on its back (pack-facing) side with integral webbing adjusters 198 that enable the pack 10 to be directly connected to an external pack frame.
- the straps 196 are designed to interface with the Downeast, Inc., 1606 air assault frame.
- Two of the webbing straps 196 are designed to engage the D-rings on the back (pack-facing) side of the waist belt.
- the webbing adjusters 198 enable the position of the central support 192 to be adjusted relative to the frame and/or waist belt 160 to accommodate a range of user sizes.
- the shoulder straps 194 are sewn directly to the padded central portion 192 and extend at an angle outward from the centreline of the pack to the shoulder area of the user.
- the non-adjustable, padded section of the shoulder straps extends approximately 19 inches from the central support.
- the padded shoulder straps are reinforced over their length by webbing sewn onto their back/top/front (away from the user) surfaces. This webbing incorporates a loop 200 just above the central support that enables the shoulder straps 194 to engage the upper cinch strap 72 when no external frame is used.
- the webbing also enables the shoulder straps 194 to incorporate female quick-release buckles 202 at their ends that interface with corresponding male buckle connectors (with integral webbing adjuster) and webbing straps.
- the shoulder straps 194 are designed to connect to the shoulder strap D-ring connectors 108 on the lower, outside portion of the main compartment back panel 100.
- the D-ring connection is made via a sewn loop in the shoulder strap webbing.
- the shoulder strap 194 is simply disconnected from the buckle 202 on the padded portion of the shoulder strap 194, the webbing loop is passed through the D-ring 100, and the male buckle is then passed through the webbing loop.
- the shoulder straps 194 are tightened via a length of webbing 210 that passes through the aforementioned integral webbing adjuster on the male buckle. The user pulls downward on each free webbing strap loop 210.
- the shoulder straps 194 are loosened by pulling up on the free webbing strap loops and releasing the frictional lock action of the webbing adjuster 198.
- Each shoulder strap 194 can be adjusted independently of the other.
- the shoulder straps 194 incorporate webbing control straps 212 that interface with webbing adjusters sewn to the front (user-facing) panel of the main compartment near the top.
- the control straps 212 are sewn to the padded shoulder straps 194 near the apex of the curve made when they are worn by a user.
- the adjustable connection between the front panel 100 of the main pack body 12 and the shoulder straps 194 enables the shoulder straps to react the overturning moment of the offset pack load, but also allows the user to adjust the amount of load transmitted to the shoulders as well as the orientation of the pack 10 relative to the shoulders. This adjustment allows the user to reposition the pack depending on terrain.
- the padded section of the shoulder straps incorporates a lateral strap system 214 that connects the two shoulder straps 194 in the chest area. This is accomplished with tensioned webbing loops 216 between the quick-release buckles 202 and the shoulder strap control webbing 212 at the shoulder curve apex.
- the lateral strap system 214 consists of two webbing straps--each with a loop 216, a webbing slide 218, and a buckle portion 220.
- the webbing loop 216 passes around the circumference of each padded shoulder strap 194 and is guided vertically by the webbing slides 218. The vertical adjustment allows the lateral strap system 214 to be adjusted depending on user height and preference.
- the shoulder straps 194 incorporate D-rings 222 that are anchored just above the lateral strap system 214 adjacent to the location where the shoulder control straps 212 attach to the shoulder strap 194.
- the area is reinforced with a strip of 2-inch webbing 224.

Figures 26 to 29 are views of a detachable bottom compartment of the pack. - The drawings illustrate a
backpack 10 which is medium-sized and includes amain pack body 12. Themain pack body 12 consists of 3 compartments--one largemain compartment 20, and two sewn-on, secondary compartments (one upper 22, one lower 24) on the backside of thepack 10. The volume of themain pack body 12 is approximately 3100 cubic inches. - Two
detachable side pouches 14 are provided. Theside pouches 14 are approximately 100 cubic inches each in volume. A detachable bottom pouch 16 (Figs. 26-29 ) is larger in volume, approximately 400 cubic inches. -
Figures 1 and2 are views of thepack 10 with various features and components labelled. The twodetachable side pouches 14 are shown attached to thebackpack 10. The larger detachable bottom pouch orbottom compartment 16 is shown inFigs. 26-29 . - The
pack 10 itself does not include an internal or external frame, but is compatible with existing external frames. Thus, thepack 10 can be used alone, or with an external frame. One preferred frame is sold by Down East Inc. as #1606 MOLLE Pack Frame [MOLLE = Modular Lightweight Load-carrying Equipment]. - The main compartment 20 (
Figs 1-3 ) spans the entire height of the pack. Themain compartment 20 includes, on its inside, a pocket 30 (Fig. 3 ) on the front side 32 (user side) of the compartment. The pocket 30 runs the entire height of themain compartment 20 and is sized to fit a radio or M8 mortar base plate. The pocket 30 is open to the top and its contents are retained via a single, centrally locatedcinch strap 34. - The
main compartment 20 is closed from the environment by an integral spindrift collar 36 (a cover that can be shut with a drawstring), as well as by a separatedetachable lid 40.Figures 4 and5 show thepack lid 40. Thedetachable lid 40 is secured to the pack via fourlid straps hook fastener tape 46 along the front (user side) edge and rear edge of the lid. The two rear lid straps 42 are located on thelid 40 itself, and engage rear lid buckle connectors 48 (Fig. 2 ) on the pack; the two forward lid straps 44 are located on the pack, and engage connectors 50 (Fig. 4 ) on thelid 40. Thehook fastener strip 46 on thelid 40 interfaces with a matching loop strip sewn to the front 32 (user-facing) and rear panels 54 of themain compartment 20. The hook-and-loop connection allows thelid 40 to hinge forward when the fourlid straps - The lid straps 42, 44 are adjustable at their buckle connections to accommodate different sizes of internal contents for the
main compartment 20, while allowing thepack 10 to be cinched down to minimize (conform) its volume to its internal contents. The rear lid straps 42 are formed by shaped panels 56 (Fig. 4 ) of material integral to thelid 40 that are sewn to webbing straps. The rear lid straps 42 connect to buckles 48 sewn to the side panels of themain compartment 20 just below the upper cinch straps 72. The forward lid straps 44 are made from webbing sewn directly to the side panels just below the upper cinch straps 72, and attach to thelid 40 via abuckle 50 sewn directly to the lid. - The detachable pack lid 40 (
Fig. 4 ) incorporates PALS [Pouch Attachment Ladder System] -compatible (or MOLLE-compatible) webbing 58 on its top, external surface to facilitate the attachment of accessories. Specifically, sufficient PALS webbing 58 is incorporated to enable the attachment of a hydration carrier. -
Figure 5 is a view of the underside of thepack lid 40. To enhance the functionality of thedetachable lid 40, the lid incorporates on its underside anintegral pocket 60. Thepocket 60 is substantially the same size as thelid 40, and has an opening along the front (user-side) edge that is closed via hook-and-loop tape 62. Thispocket 60 can be used for storage of miscellaneous accessories. In addition, because thelid 40 is detachable, thepocket 60 can be filled with necessities and the lid used as an escape and evasion pack when theentire backpack 10 cannot be carried. - The lid 40 (
Figs. 5-6-7 ) incorporates overlappingflaps flaps main compartment 120. Theseflaps lid 40, but can be disengaged to create a small gap or opening 66 in the front, outer corners of the lid.Figures 5 ,6, and 7 contain views of the front edge of thepack lid 40 with the overlapping flaps 64.Figure 6 shows theflaps Figure 7 shows the flaps in the gap (open) orientation. - The
pack 10 can be used without thedetachable lid 40. To that end, thepack 10 includes a large spindrift collar 36 (Fig. 8 ) that is sewn to and closes off themain compartment 20. Thespindrift collar 36 allows themain compartment 20 to be closed off via adrawstring 70 at the collar's upper perimeter. Thespindrift collar 36 also maximizes the water resistance of themain compartment 20, as it leaves a minimal opening to the main compartment when cinched. Thespindrift collar 36 extends approximately 7.5 inches above the top edge of themain compartment 20. The flexibility and length of thespindrift collar 36 allow thepack 10 to expand in volume above themain compartment 20, and to accommodate items that are taller/longer than the main compartment. - In addition to the vertical volume control via the lid straps, the size of the
main compartment 20 can also be adjusted horizontally (laterally) via upper and lower cinch straps 72, 74 (Fig. 2 ) on either side of the pack. This allows themain compartment 20 to be cinched in a horizontal fashion to minimize (conform) its volume to its internal contents. The upper and lower cinch straps 72, 74 are also designed to enable thepack 10 to be mounted onto an external frame, and serve as the primary interface with the frame. In particular, thepack 10 andstraps pack 10 is attached to an external frame. - The
upper cinch strap 72 runs nearly horizontally slightly above the midline of themain compartment 20. Thestrap 72 anchors to a webbing strap via adjustable buckles 76 (Fig. 10 ) on the back (rear-facing) panel of themain compartment 20 between the upper and lowersecondary compartments upper cinch strap 72 runs continuously from one side around the front (user-facing) panel of thepack 10 and back to the other side, connecting to the webbing strap via theadjustable anchor buckle 76. The lower cinch strap 74 (Fig. 2 ) runs horizontally near the bottom edge of thepack 10 and anchors to the back (rear-facing) panel of the lowersecondary compartment 24 on one end via anadjustable buckle 78, and on the other end to the front (user-facing) panel of the main compartment via a sewn connection. - The cinch straps 72, 74 can be tightened and the
main compartment 20 compressed down to its contents by the user pulling forward (toward the front panel) on the length of free webbing strap. Conversely, the cinch straps 72, 74 can be loosened by rotating the forward edge of theappropriate buckle - The external side panels of the main compartment include webbing guides 80 (
Fig. 2 ) for theupper cinch strap 72, as well as PALS-compatible webbing 82--one row in the upper area of the side panel for small accessories, and four rows at the bottom of the side panel for attachment of theside pouches 14 or other PALS-compatible accessories. ThePALS webbing 82 and the upper cinch strap webbing guide 80 are shown inFigures 1 and2 . -
Figure 9 shows the bottom (ground-facing) panel 90 of themain compartment 20. The bottom panel 90 incorporates additional rows of PALS-compatible webbing 92, oriented fore-aft. Two rows are situated near the side, with an additional two rows on either side of the centreline of the pack. Two additional mountingstraps 94 are provided on the bottom panel 90 of the pack between the PALS-compatible webbing 92, on either side of the pack centreline. Theadditional straps 94 are constructed from a combination of 1-inch and 2-inch webbing and allow accessories to be attached to the pack. Specifically, they are designed to enable the detachable bottom compartment 16 (Figs. 26-29 ) to be attached to themain pack compartment 20 of thepack 10. -
Figure 10 shows the webbing loops and upper cinch strap buckles of themain pack body 12. The back panel (rear-facing) of the main compartment supports the removable upper (22) and lower (24) secondary compartments, as well as the upper cinch strap buckles 76. The cinch strap buckles 76 are anchored to the back panel near the side panels. The back panel also incorporates a strip of webbing 96 with four large loops for attachment of accessories in between the two upper cinch strap anchor points. -
Figure 10A shows the front (toward the wearer) panel 100 of the pack 10 (the pack's suspension system, described below, is removed). A strip ofloop fastener tape 102 is sewn to the upper, centre portion of the front panel. This strip connects with thehook fastener tape 46 on the front detachable edge of thelid 40, to provide a releasable hinge connection between the lid and themain compartment 20 when the lid straps 42, 44 are disconnected. - To facilitate attachment of the pack's suspension system (described below), the front panel 100 incorporates sewn webbing loops with attached
webbing adjusters 104 near the top of themain compartment 20. These provide mounting locations for shoulder strap control connections that connect near the top apex of the shoulder straps. Thewebbing loops 104 are sewn directly on top of the portion of thetop carry handle 106 that is sewn to the front panel on either side of the vertical centreline. - To interface with the bottom end of the chest-side of the shoulder straps, the front panel 100 incorporates D-rings 108 near the bottom edge of the front panel near the side panels. Directly adjacent to the shoulder strap D-rings 108, the front panel also incorporates anchor points for the
lower cinch strap 74, as well as two webbing adjusters 110 for use with an external frame. Thelower cinch strap 74 is sewn to the front panel 100. The webbing adjusters 110 allow thelower cinch strap 74 to be tightened around the frame while leaving the remaining length of webbing usable as a cinch strap. - Similarly, the front panel 100 incorporates sewn anchor points for the continuous
upper cinch strap 72 near the midline of the front panel. This is necessary as the upper cinch strap is utilized to attach the shoulder straps when the suspension system is used without an external frame. - Padding is sewn into the front panel 100 of the
main compartment 20 to facilitate carrying hard body armour plates and/or other similarly accessories. The padding preferably has an upside down U-shape and runs from approximately the midline of the back near the sides up to the top; around to the middle of the front panel; over to the other side; and then back down symmetrically to the middle of the front panel 100. The padding is preferably a strip of padding approximately 2 inches wide. - To accommodate the waist belt 160 (described below), the front panel 100 incorporates a lateral pocket 114 near the bottom of the front panel. The lateral pocket 114 is a panel of fabric sewn to the front panel 100 with openings at the side of the pocket, as well as the top, to enable the backside of the
shoulder straps 194 to connect to thewaist belt 160. - The front panel 100 also includes an
upper pocket 116 near the top edge of the panel to enable the use of an external frame. Theupper pocket 116 is a panel of fabric sewn to the front panel with an opening that faces down, and having a cut-out in the upper edge to allow the shoulder strap control connections to pass through. In particular, theupper pocket 116 is designed to interface with the Downeast, Inc., 1606 air assault frame. - The front (user-facing) panel incorporates three carry handles--one top carry
handle 106 and two side carry handles 118. The top carryhandle 106 is located at the top of the front panel, just below theloop fastener strip 102 that interfaces with thelid 40, and is sewn to the front panel directly underneath the webbing loops. The side carryhandles 118 are located just below theupper cinch strap 72. For maximum structural performance, the webbing that forms the side carry handles 118 is continuous and spans the entire width of the front panel 100 as shown in dashed lines inFigure 10A , and is sewn to the inside of themain compartment 20. The position and structural nature of the side carry handles 118 allow thepack 10 to be carried on its side, but also allow a disabled wearer to be moved efficiently by two persons each grasping a side carryhandle 118 in an improvised litter carry, lifting thepack 10 directly and, indirectly thereby, the wearer of thepack 10. - The upper
secondary compartment 22 is shown inFigures 11 and12 . The uppersecondary compartment 22 is located on the upper back (rear-facing) surface of themain compartment 20 and is sewn directly to the main compartment. The approximate dimensions (in inches) of the uppersecondary compartment 22 are 13w x 7h x 5d. The uppersecondary compartment 22 is accessed via a slide/zip closure 120 that runs around the upper half of its rearmost perimeter. -
Figure 12 shows the inside of the upper secondary compartment. The uppersecondary compartment 22 includes a mesh pocket 122 attached to the inside of the rear-facing panel of the upper secondary compartment. The mesh pocket 122 runs the full width of thecompartment 22 and is approximately 5.5 inches tall. Two snaps 124 are provided on the inside panel of the compartment to enable a 6 magazine bandoleer to be mounted inside. - The rear-facing surface (
Fig. 11 ) of the uppersecondary compartment 22 incorporates three rows of PALS webbing 126 to enable the attachment of PALS-compatible accessories or other hardware. In addition, a 1-inch strip of loop fastener tape 128 is sewn onto the rear-facing surface of the pocket to enable identification or other information to be attached to the pack as necessary. The tape strip 128 runs laterally across the rear-facing panel of the compartment between the first and second rows of PALS webbing 126. - The upper
secondary compartment 22 incorporates vertical cinch straps 130. The lower ends of the vertical cinch straps 130 are sewn to the main compartment just below theupper compartment 22. The upper ends of the vertical cinch straps 130 connect to buckles 132 on themain compartment 20 at the top of the pocket 122. The cinch straps 130 enable the uppersecondary compartment 22 to be cinched down to minimize (conform) its volume to its internal contents. The cinch straps 130 also provide structural support to the slide/zip closure 120 of the uppersecondary compartment 22. The lateral location of the vertical cinch straps 130 is such that they can be run underneath the rows of PALS webbing 126, helping to reduce entanglement potential. - The lower
secondary compartment 24 is shown inFigures 13-15 and is similar in construction to the uppersecondary compartment 22. The lowersecondary compartment 24 is located on the lower back (rear-facing) surface of themain compartment 20 and is sewn directly to the main compartment approximately 2 inches below the uppersecondary compartment 22. This separation between the lowersecondary compartment 24 and the uppersecondary compartment 22 provides a gap for receiving accessories or for allowing a rifle to be nested between the twocompartments -
Figure 14 is a view of the inside of the lowersecondary compartment 24. The approximate dimensions (in inches) of the lowersecondary compartment 24 are 15w x 12h x 7d. The lowersecondary compartment 24 is accessed via a slide/zip closure 136 (Fig. 14 ) that runs around the upper half of its rearmost perimeter. - The lower
secondary compartment 24 includes a mesh pocket 138 sewn to the inside of the rear-facing panel of thecompartment 24. The mesh pocket 138 runs the full width of the compartment and is approximately 6.5 inches tall. Twosnaps 140 are provided on the inside panel of thecompartment 24 to enable a 6 magazine bandoleer to be mounted inside. -
Figure 15 is a view of the lower portion of the lowersecondary compartment 24 and the lower cinch strap buckle connection. The rear-facing surface of thecompartment 24 incorporates three rows of PALS webbing 142 to enable the attachment of PALS-compatible accessories or other hardware. The bottom row of PALS webbing 142 is used as the anchor point for the lower cinch strap buckles 78. - A 2-inch strip of loop fastener tape 144 (
Fig. 13 ) is sewn onto the rear-facing surface of thecompartment 24 to enable identification or other information to be attached to thepack 10 as necessary. Thetape strip 144 runs laterally across the rear-facing panel of the compartment above thePALS webbing 142. - The lower
secondary compartment 24 incorporates two vertical cinch straps 146. The vertical cinch straps are anchored just below the compartment and connect to buckles at the top of thecompartment 24. The cinch straps 146 enable thecompartment 24 to be cinched down to minimize (conform) its volume to its internal contents, as well as to provide structural support to the slide/zip closure 136. The lateral location of the vertical cinch straps 146 is such that they can be run underneath the PALS webbing 142 helping to reduce entanglement potential. - The
pack 10 includes two identicaldetachable side pouches 14.Figure 16 shows a front view of adetachable side pouch 14, andFigure 17 a back view. Thepouches 14 are approximately 9h x 7w x 4d in size (in inches) and includeattachment webbing 149 that interfaces with the PALS webbing on the lower part of the main compartment side panels. - Each
side pouch 14 has a top flap closure 150 that is secured via a snap buckle that includes a female buckle end 154 mounted to the flap 150 and amale buckle end 156 adjustably attached to the front side of thepouch 14 via a webbing strap. Thepouch 14 is sized to accommodate standard sustainment rations or other miscellaneous items. Thepouch 14 incorporates two rows of PALS-compatible webbing 158 on its vertical, external face. - The detachable bottom compartment 16 (
Figs. 26-29 ) is generally similar in configuration to the detachable side pouch and is designed to interface with the PALS-compatible webbing 92 and the 2-inch straps 94 located on the bottom panel of themain compartment 20. The detachablebottom compartment 16 is approximately 13h x 9w x 5d in size (in inches) and is sized to carry a set of boots, a sleep system, or other miscellaneous equipment. - The detachable
bottom compartment 16 is accessed via a slide/zip closure 230 that runs around the upper half of its rearmost perimeter. The detachablebottom compartment 16 incorporates two cinch straps 232. The cinch straps 232 are anchored to the forward (user-facing) top (facing the bottom of the main compartment 20) surface of thebottom compartment 16 and loop around the entire circumference to connect to buckles 234 on the rear-facing portion of the top surface. The cinch straps 232 enable the compartment to be cinched down to minimize its volume to its internal contents, as well as provide structural support to the slide/zip closure 230. This structural support enables the compartment to be filled to capacity while reducing the potential for failure of the slide/zip closure 230. - The detachable
bottom compartment 16 also includes two laterally extending snap-fastener straps 236. Thestraps 236 when disengaged can be slid through the 2inch webbing 94 on the bottom of themain compartment 20 and then snapped closed, to support thebottom compartment 16 on themain compartment 20. Thestraps 236 can also be connected through standard PALS webbing. Thus, the detachablebottom compartment 16 is PALS-compatible and can be attached to any PALS-compatible equipment. - The
pack 10 includes a suspension system that includes two main components--a waist belt or loaddistribution belt 160 and ashoulder strap system 190.Figures 18 and 19 are front and back views of thewaist belt 160. Thewaist belt 160 includes an internally-paddedbelt 161 with 2-inch wide webbing straps 162 extending from either end that connects with abuckle system 162, 164. The padding is provided on the portion of thebelt 161 that sits on the user's back, and extends around to the hip area. The length of padding is approximately 30 inches. The profile and top and bottom edges of thewaist belt 160 are contoured to provide maximum comfort for the user while maintaining compatibility with body armour. - To retain the loose ends of the
webbing 162 and to enable thewaist belt 160 to be tightened in both forward and rearward pull directions, thewebbing 162 passes through a 2-inch D-ring 168 on each side after passing through theadjustable buckle 162, 164. The D-rings 168 are sewn into thewaist belt 160 near the end of the padded portion. - The
waist belt 160 attaches to themain pack body 12 by sliding laterally through the lower pocket 114 (Fig. 10A ). Vertical (downward) loads are transmitted from themain pack 12 to thewaist belt 160 and thereby to the wearer's waist and hips. - The
waist belt 10 incorporates a pair of diagonal reinforcing straps 170 (Fig. 20 ) on either side in the hip area to help carry the vertical loads into the cantilevered portion of the waist belt in the hip area of the user, while minimizing twist in the waist belt. Thestraps 170 are sewn to the back (pack-facing) side of thewaist belt 160 and are anchored adjacent to the point at which the waist belt is loaded by the pack or where the waist belt is connected to an external frame. Thestraps 170 begin at the top and bottom edges of thewaist belt 160 and converge diagonally to the waist belt webbing anchor point and tightening D-ring 168. A 2-inch piece ofwebbing 172 reinforces the connection at one end and a 1-inch piece of webbing 174 reinforces the connection adjacent to the pack/frame attachment. - The diagonal orientation of the
straps 170 allows the top and bottom edges of thewaist belt 160 to react well to vertical loads. In contrast, typical waist belt designs are constructed with a webbing strap centrally-located on the waist belt. Such a centrally-located strap tends to deform and roll the waist belt over when the waist belt system is loaded. Thediagonal straps 170 are pretensioned before being sewn to thewaist belt 160. This pre-tensioning helps thewaist belt 160 better react vertical waist belt loads by removing potential slack, and also forces the belt sides into an open configuration that is more easily donned. - To facilitate attachment of the shoulder strap system 190 (described below), the
waist belt 160 incorporates two shoulder strap D-ring connectors 176 (Fig. 20 ). The shoulder strap D-ring connectors 176 are sewn near the vertical centreline of thewaist belt 160. - To facilitate attachment of the
waist belt 160 to an external frame, the waist belt incorporates two additional strap connectors 180 (Fig. 19 ), one located on each side of the vertical centreline of the back (pack-facing) side. Eachstrap connector 180 includes a webbing loop and a webbing adjuster - As it is desirable to drive as much of the pack load as possible to the
waist belt 160, thepack 10 includes ashoulder strap system 190 that connects directly to thewaist belt 160 instead of directly connecting to themain pack body 12.Figures 21 and22 are front and back views of theshoulder strap system 190.Figure 23 is a view of thepack 10 with the shoulderstrap suspension system 190 directly attached. - The
shoulder strap system 190 includes a paddedcentral support 192 and two padded shoulder straps 194. Thecentral support 192 is designed to sit directly on the user's back, inside the pack itself. Thecentral support 192 incorporates fourwebbing straps 196 on its back (pack-facing) side with integral webbing adjusters 198 that enable thepack 10 to be directly connected to an external pack frame. In particular, thestraps 196 are designed to interface with the Downeast, Inc., 1606 air assault frame. Two of the webbing straps 196 are designed to engage the D-rings on the back (pack-facing) side of the waist belt. The webbing adjusters 198 enable the position of thecentral support 192 to be adjusted relative to the frame and/orwaist belt 160 to accommodate a range of user sizes. - The shoulder straps 194 are sewn directly to the padded
central portion 192 and extend at an angle outward from the centreline of the pack to the shoulder area of the user. The non-adjustable, padded section of the shoulder straps extends approximately 19 inches from the central support. The padded shoulder straps are reinforced over their length by webbing sewn onto their back/top/front (away from the user) surfaces. This webbing incorporates aloop 200 just above the central support that enables theshoulder straps 194 to engage theupper cinch strap 72 when no external frame is used. The webbing also enables theshoulder straps 194 to incorporate female quick-release buckles 202 at their ends that interface with corresponding male buckle connectors (with integral webbing adjuster) and webbing straps. - The shoulder straps 194 are designed to connect to the shoulder strap D-ring connectors 108 on the lower, outside portion of the main compartment back panel 100. The D-ring connection is made via a sewn loop in the shoulder strap webbing. The
shoulder strap 194 is simply disconnected from the buckle 202 on the padded portion of theshoulder strap 194, the webbing loop is passed through the D-ring 100, and the male buckle is then passed through the webbing loop. The shoulder straps 194 are tightened via a length ofwebbing 210 that passes through the aforementioned integral webbing adjuster on the male buckle. The user pulls downward on each freewebbing strap loop 210. Conversely, theshoulder straps 194 are loosened by pulling up on the free webbing strap loops and releasing the frictional lock action of the webbing adjuster 198. Eachshoulder strap 194 can be adjusted independently of the other. - Although the primary vertical load path of the
shoulder belt system 190 is through the waist belt 160 (in lieu of the pack 10), the shoulder belt system must also react the overturning moment of the offset pack load. To accomplish this, theshoulder straps 194 incorporate webbing control straps 212 that interface with webbing adjusters sewn to the front (user-facing) panel of the main compartment near the top. The control straps 212 are sewn to the paddedshoulder straps 194 near the apex of the curve made when they are worn by a user. The adjustable connection between the front panel 100 of themain pack body 12 and theshoulder straps 194 enables the shoulder straps to react the overturning moment of the offset pack load, but also allows the user to adjust the amount of load transmitted to the shoulders as well as the orientation of thepack 10 relative to the shoulders. This adjustment allows the user to reposition the pack depending on terrain. - To help maintain the position of the
shoulder straps 194 on the shoulders, the padded section of the shoulder straps incorporates a lateral strap system 214 that connects the twoshoulder straps 194 in the chest area. This is accomplished withtensioned webbing loops 216 between the quick-release buckles 202 and the shoulder strap control webbing 212 at the shoulder curve apex. The lateral strap system 214 consists of two webbing straps--each with aloop 216, a webbing slide 218, and abuckle portion 220. Thewebbing loop 216 passes around the circumference of eachpadded shoulder strap 194 and is guided vertically by the webbing slides 218. The vertical adjustment allows the lateral strap system 214 to be adjusted depending on user height and preference. - For attachment of accessories, the
shoulder straps 194 incorporate D-rings 222 that are anchored just above the lateral strap system 214 adjacent to the location where the shoulder control straps 212 attach to theshoulder strap 194. The area is reinforced with a strip of 2-inch webbing 224. - The
pack 10 is designed to interface with an external frame system such as the Downeast, Inc., 1606 air assault frame. The frame interfaces with themain pack body 12 via theupper pocket 116 on the front (user-facing) pack panel, and the upper and lower cinch straps 72 and 74. When a frame is used with thepack 10, the suspension system is disconnected/disengaged from the pack and is connected to the frame, with the exception of the shoulderwebbing control strap 212 connection which is retained.Figure 24 is a view of the pack and suspension system attached to the 1606 air assault frame.Figure 25 is a view of the back of the 1606 air assault frame with the suspension system attached. - The
