ADJUSTABLE BACKPACK STRAPS
Abstract of the Disclosure An adjustable backpack structure including a base mem-ber adapted to be secured to a backpack and carrying thereon at least one elongated track, a moveable member including attachment structures for backpack straps and configured to be moveably engaged by the base member track, and a locking structure to releasably secure the moveable member in a selected position and along the base member track whereby the base member may be conveniently sewn or otherwise attached to a backpack with the track disposed in a dir-ection in which adjustability of the backpack straps is desired, and the moveable member carrying the straps secured to the base member along the track at any of a number of positions by releasing and securing the locking structure.
Description
~'7~
Background of the Invention This invention relates generally to the attachment and adjustment of straps to backpacks or rucksacks, and more particularly pertains to an assembly-includiny a base member adapted to be secured to the backpack and including prefer-ably a pair of parallel track members, a moveable member adapted to ride along the track members and carry the back-pack straps, and a locking structure to secure the moveable member at selected positions along the track me~.bers.
Descri~tion of the Related Art It is generally well recognized in the backpack or rucksack industry that the physical characteristics of an individual wearing a particular sack will require different adjustments of the attachment points of the various body straps and other attachment portions bearing upon the wearer. Cenerally the attachment portions include shoulder straps, a lower back pad, and often a waist belt. ~lereto-fore the strap por~ions have been made adjustable by pro-viding a plurality of redundant attachment points or a single attach~ent point with a plurality of guides to position the effective attachment of the shoulder strap to the backpack. Such redundant at~achment points are expen-sive, cumbersome, and expensive, and usually require a good deal of effort to change the particular adjustment. Such ~` ~z'~
prior approaches have generally involved substantial labor to provide individual positioning of and sewing of the multiple attachment points.
Sun~.ary of the Invention The present invention, which provides a heretofore unavailable convenience and economy in attachment of adjust-able backpack straps comprises a structur~ in which a base member, preferably of a polymer or similar such material, is produced in a form providing for convenient attachment through sewing, rivoting or similar means to a backpack.
Carried on the lightweight base member is at least one, but preferably two rail or track members extending in a parallel relationship in the direction in which adjustment of the straps is desired. A moveable member including an arrange-ment, usually slots, adapted to receive the straps is con-figured to engage and move along the rail members in such a fashion as to provide a strong interface with easy and con-venient relocation. A releasable locking structure is pro-vided between the base member and moveable means to secure the moveable member at any of the plurality of positions relative to the base member. Thus, the backpack straps may be conveniently attached to the base member with the simple positioning of the rnoveable member on the rail melllbers, and both adjusted and secured by means of the releasable locking structure.
'7S~
The invention in one broad aspect pertains to structure for adjustably mounting attachment points to a pack member, the structure comprising a base plate adapted to be secured to the pack member and having defined thereon at least one elongated track and a moveable member slidingly carried on the base plate at the track, the moveable member including attachment point mounting structure and track engaging means for slidably securing the moveable member to the base plate. Locking means is carried on the attachment structure and interacts between the moveable member and base plate to releasably secure the moveable member against sliding movement at predetermined positioning on the base plate.
The base plate track comprises a plurality of parallel tracks and the moveable member includes track engaging means contacting the parallel tracks. The parallel tracks comprise a pair of undercut rail members with the undercut portion being on the side opposite the moveable member and the track engaging means includes portions which f.it in-to the undercu-t portions to secure the moveable member to the base plate in a sli.ding manner.
Another aspect of the invention comprehends an adjustable attachment structure comprising a base plate capable of being secured to a backpack and having a pair of long:itudinally extending and laterally spaced tracks together defining a pair of undercut inwardly facing parallel rails on a surface of the base plate intended to face away from the backpack. There is a 2S moveable member including attachment point mounting means and track sliding contacting means and locking means interacts equally between the moveable member and both of the rails for releasably securing the movable member at predetermined positions relatively to the rails. One of the track sliding contacting means an~ the s~
locking means includes portions which fit into the undercut portions of the rails -to secure the respective one of the track sliding contacting means and the locking means to the base plate in a manner permitting only longitudinal sliding thereof. The locking means includes a pair of locking portions moveable into and out of locking interaction with respective ones of the rails under the control of a locking mechanism located laterally between the rails.
These and other aspects and features of the present invention will become apparent with consideration of the following description.

Figure 3 :Ls a top view of the structure set forth in Figure 2;
Figure 4 is a front view of a structure similar to that of Figure 2 but illustratillg a different locking structure;

~q ~2~'75~3 Detailed DescriPtion of the Invention Turniny now to the drawings, wherein like elements are designated by like reference numerals throughout the various figures, bacXpack 10 including adjustable backpack attach-ment assembly 12 is shown in FIGURE 1. Adjustable shoulder strap attachment assembly 12 includes a base member 14 typi-cally attached by stitches 16 to backpack 100 A pair of parallel undercut rail members 18 are defined on base member 14 and include a plurality of opposed openings 2~ defined therein as will be discussed in more detail below. Moveable member 24 is configured to engage and slide within rail members 18 as is illustrated in more detail in FIGURES 2 and 3. A pair of openings 26 are defined throush moveable mem-ber 24 and adapted to receive backpack shoulder straps 28.
lS Locking assembly 30, which is attached to moveable member 24 by enclosures 32 defined thereon, includes a U-shaped dis-tendable member 34 carrying a pair of outward facing dogs 35 on either side thereof. Dogs 35 are arranged to engage a pair of opposed openings 20. Accordingly, moveable member ~ 4 7~
24 may be conveniently slid along rails 18 by depressing U-shaped member 32 to disengage dogs 35, and thereafter secured in place by releasing the pressure on U-shaped member 34 to allow dogs 35 to engage the adjacent opposed openings 20. In actual practice, openings 20 may be closely spaced to provide for finer adjustment. However, for pur-poses of illustration, FICURE 1 is believed to convey the principle to those skilled in the art.
Thus, as will be particularly apparent in FIGURE 3, moveable member 24 is configured to engage and fit under the undercut portions of opposed rail members 18 thereby move-ably attaching moveable member 24 to base member 14. Unless otherwise secured, moveable member 24 will readily slide along rail ~lembers 18. ~owever, as is shown in FIGURE 2, openings 20 defined in rails 18 are configured to receive doys 35 and thus prevent movement of moveable member 24. ~y compressing U-shaped member 3~, dogs 35 may be retracted from openings 20 thereby permitting positioning of moveable member 24 to the desired location, whereupon dogs 35 can again engage an opposed pair of openings 20. As discussed above, openings 20 may be defined closely adjacent one another to provide for fine adjustment of moveable member 24 relative to base member 14. Also, though FIGURES 1 through 3, and the other figures of this description, particularly 7~
pertained to adjustable attachment assembly 12 configured to receive shoulder straps 18, it will be readily recognized to those skilled in the art that a similar assembly could readi-ly be configured to carry a backpack attachment, or a back-pad, etc. Further, it will be recognized by those skilled in the art that a polymeric base member 14, molded of, for instance, urethane plastic, will have sufficient flexibility to facilitate attachment by sewing and provide adequate conformity to the somewhat pliable backpack 10 while still having sufficient rigidity to permit moveable member 24 to slide therealong.
As shown in FIGURE 4, a modified backpack attachment assembly 12' is illustrated. Basically, base member 14' is essentially identical to that illustrated in FIGURE 1 except that the opposed holes 20 of FIGURE 1 are omitted. Moveable member 24' also is essentially as shown in FIGURE 1 except that camming loc~ing structure 40 is utilized. ~s shown, locking structure 40 includes a pair of members 42 having notched, arcuate camming surfaces 44 on opposed ends there-of. Member~ 42 are at~ached one to the other and to move-able member 24' by pivot 45 such that camming surfaces 44 can effectively be retracted by graspiny members 42 and rotating around pivot 45 in a scissor fashion. However, when released, spring 46 urges the notched camming surfaces .
75~
44 into engagement with adjacent rails 18'. Accordinsly, particularly when an upward load is applied such as would be applied by shoulder straps from moveable member 24' relative to base rnember 14', notched carnming surfaces 44 will secure-ly jam against adjacent rails 18' thereby providing for secure locking of moveable rnember 24' relative to base nlember 14'. Since, in the case of shoulder strap load application, the load in essentially in one direction, camming lockiny structure 40 is quite effective for this particular purpose. For bidirectional loads, locking assembly 30 of FlGURE 1 is more positive. Those skilled in the art will readily recognize the advantages and disad-vantages of the two approaches. It is to be understood that the particular embodiment best suited for a given use may well be dependent upon the particular use of the underlying invention.
FIGURE 5 illustrates yet another configuration of the invention. As shown, adjustable backpack attachment assem-bly 12" includes all of the functional features of the previous embodiment, though in a different configuration.
For instance, base member 12" again includes a pair of opposed rails 18", but the rails are more closely spaced.
Similarly, moveable member 24" again engages undercut rails 18" but the locking assembly differs. ~lith reference to FIGURE 6, which is a sectional view along section line ~;~4'7~
VI-VI, the section view illustrates the manner in which moveable member 24" rides on the outer portions of opposed rail members 18". However, screws 50 extend through move-able member 24" and are threadedly engaged by plate 52 which extends beneath the undercut portions of rail members 18".
Thus, by loosening screws 5~, shown in FIGURE 5 as being three in number, the clampin~ action is released and move-able member 24" may be slid along rails 18" in an apparent manner. However, when moveable member 24" is appropriately positioned, screws 50 may again be tightened thus providins for a clampin~ of plate 52 bearing upon the underside of undercut rail members 1~" and also a clamping of moveable member 24" to base member 14".
It will be recognized that the various embodiments, lS i.e. that of FIGURES 1-3, that of FIGU~E 4, and that of FIGURE 5 and ~, all contain common elements, i.e. a base member adapted to be secured to a backpack, a moveable mem-ber adapted to engage rails defined on the base member to slide tllerealong, and locking means to releasably secure the moveable member to the base member. It is anticipated that various other configurations of these elements will be readi-ly apparent and perhaps e~ually operable. Though numerous materials may be employed depending upon a particular nature of the backpack, i.e. internal frar,le, external frame, etc., in general a somewhat pliable polyurethane material, i.e. a 90 durometer material is con~emplated for the base member and the moveable member. On the other hand, the locking member is usually of a more rigid plastic such as a poly-carbonate or DELRIN polymeric material, or may also be ~lade of metal. Particularly the embodiment of FIG~RE 6 may well be advantaseously formed of metal for strength of the threaded areas, though metal inserts in a plastic plate are also possible. However, the materials mentioned are merely currently preferred though not critical choices and it is expected that many other choices will serve adequately.
In sun~ary, the adjustable backpack strap attachment assembly disclosed and discussed herein has the advantage of simplicity, lightness and additional strength. As will be apparent, all of the forces transferred from the assembly to a backpack will be spread over the entire attachment of the base member. ln many prior art arrangements, a selected attachment point bears all of the load and other alternative attachment points are essentially load free. Further, rapid and convenient adjustment over a substantial range is pro-vided the user of the assembly. A particular backpack may be produced by merely attaching the base member, which is arnenable to machine sewing or other mechanized attachmen means in a straight forward, econornical manner. In this * trademark A

fashion, economy and manufacturing case are achieved as well as enhanced performance provided to the user.
11hile only the presently preferred embodiment and com-ponents of the instant invention have been specified and described in detail, it will be apparent to those skilled in the art that changes and modifications may be n~,ade without deviating from the scope of the invention as defined by the following claims.
