Definitions

  • This invention relates to a shoulder pad for a rucksack harness.
  • Modern large capacity rucksacks have shoulder pads which in use extend from the scapular region at the back of a wearer to the chest region at the front, where they merge into straps connectable to lower location points on the fabric sack or its supportive frame.
  • the respective pads for right and left are connected by webbing, or by being mounted on a relatively stiff plate, in the scapular region, and these conjoined regions may be adjustably mounted onto the substantially rigid supportive frame of the sack.
  • such shoulder pads have been formed of flat pieces of foamed plastics cut out of large sheets of such material and covered by a fabric envelope.
  • the foamed plastics core has been shaped in two dimensions only (generally a curving, somewhat tapering shape) and has been of even thickness throughout.
  • a relatively stiff plate of polypropylene or similar may have been included in the envelope.
  • a rucksack harness shoulder pad which comprises an elongate moulded foam plastics core in the form of a strip and provided with a pluraltiy of transverse grooves in at least that surface which in use contacts a user's body.
  • the moulding of the foamed plastics allows integral formation of grooves at the appropriate places, at the requisite spacings, and of appropriate depth and width, so that in use the pad can extend over the shoulder of a wearer without any discomfort owing to wrinkling on the inside f the curve.
  • the grooves constitute areas where material has been removed to allow for curvature over the shoulder without wrinkling.
  • the grooves also generally improve the flexibility of the shoulder pad, allowing it all the better to adapt to the body contours of the user.
  • the aforesaid grooves extend across the side edges of the core, and thus enhance its flexibility in a side to side direction.
  • the moulded core is profiled in three dimensions. More specifically, when viewed in plan, it can have a front to rear curvature in addition to the conventional sideways curvature.
  • the foam plastics shoulder pad core may be provided with an insert of lower density foam in that surface which in use contacts the user's body.
  • Such insert should be positioned so as to overlie the sensitive front shoulder area of the user, and reduce pressure transmission where tendons connect the deltoid muscle to the clavicle and where major nerves and blood vessels pass close to the skin, so as to minimise discomfort here.
  • the foam core will be covered by fabric, which may be stitched thereon or adhered thereto as a close-fitting envelope.
  • fabric is not essential in all cases.
  • a practical embodiment of the shoulder pad of the invention may advantageously comprise four regions, as follows:-
  • an equally favourable practical embodiment may have similar regions, but be moulded so that regions (ii) and (iii) additionally have inherent front to rear curvature. This means that the entire pad is U-shaped as well as curving sidewards.
  • the aforesaid preferred embodiments may suitably be made of closed cell polyethylene foam, although the insert may be open cell.
  • shoulder pads can be produced, all conforming to the invention, but comprising different foamed plastics materials, or different densities, different shapes, (and with or without front to rear curvature), different groove positioning, varying softness and size of insert, or optional additional stiff inserts (e.g. of polypropylene), for example to suit male or female users, or users of different body size, or different rucksack capacities and intended purposes.
  • different foamed plastics materials or different densities, different shapes, (and with or without front to rear curvature), different groove positioning, varying softness and size of insert, or optional additional stiff inserts (e.g. of polypropylene), for example to suit male or female users, or users of different body size, or different rucksack capacities and intended purposes.
  • a further aspect of the present invention is a rucksack comprising a fabric sack, a supportive frame comprising at least one substantially rigid vertical member mounted at the rear of the sack, a harness comprising shoulder pads mounted on said frame and associated straps, a lumbar pad, and a hip belt, characterised in that the shoulder pads are joined together symmetrically in the scapular region and each comprises an elongate moulded foam plastics core formed with a plurality of transverse grooves in at least that surface which in use contacts the user's body.
  • the conjoined scapular region of the shoulder pads are slidably adjustable up and down the frame, which conveniently comprises two vertical bars, so as to accommodate varying user torso lengths.
  • Respective top straps connect each of the shoulder pads to attachment points at the top of the frame members or the top of the sack.
  • the purpose of these top straps is to impart upward and backward tension to the pads so as to reduce transmission of load from the sack to the sensitive front shoulder regions of the user, as mentioned above.
  • the length of these straps needs to be adjusted whenever the vertical position of shoulder pad mounting is changed. This has previously been accomplished by providing a length adjustment buckle at the attachment points on the frame or sack.
  • top strap length adjustment buckles are provided not on the frame or sack, but on the respective shoulder pads, which buckles are themselves adjustable in position -along the respective shoulder pads.
  • their take-off position from the shoulder pad can be varied.
  • the precise take-off point is important to achieving the desired pressure relief in the sensitive front shoulder region and it is dependent upon chest depth as well as torso length of user.
  • variations in chest depth could not be adequately catered for, leading to some user discomfort.
  • the positional adjustment of the top strap buckle may conveniently be achieved by sliding along a floating region of the webbing which is stitched longitudinally of each shoulder pad and extends to provide the strap for connection to the lower end of the frame or sack.
  • the foam core of the pad is, in accordance with the invention, produced by moulding it may be advantageous to mould this directly onto the webbing.
  • Fig. 1 is a rear view of a rucksack incorporating two conjoined shoulder pads in accordance with the invention, the hip belt being broken away for clarity;
  • Fig. 2 is an enlarged view of one embodiment of the shoulder pad of the invention, specifically showing the surface thereof which in use contacts a user's body;
  • Fig. 3 is a side view of the same shoulder pad in the direction of the arrow III in Fig. 2;
  • Fig. 4 is a cross-section of the same shoulder pad along the line IV-IV in Fig. 2;
  • Fig. 5 is a view corresponding to Fig. 2 of the opposite surface of the shoulder pad which in use is remote from the user's body;
  • Fig. 6 is a reduced scale perspective view of a modified embodiment of the shoulder pad of the invention.
  • Fig. 7 a, b and c are sketches illustrating three modes of use of pairs of pads in accordance with the invention.
  • this exemplary embodiment of shoulder pad 10 is moulded of foamed plastics, preferably closed cell polyethylene, and includes, intermediate its ends, an insert 12 of lower density (i.e. softer), possibly open cell foamed plastics.
  • the overall shape of the pad 10 is elongate, approximately flat, slightly curving, and also tapering so that there is a narrow end region D and a broader end region A. Between these two end regions, two other distinct regions B and C can be identified.
  • the broad end region A is relatively straight, and relatively stiff and is intended to be joined symmetrically to a corresponding region of another pad and mounted on a rucksack frame (see Fig. 1).
  • region B which is a slightly curving region provided with a plurality of transverse grooves 13 (in this case four such grooves are shown) which extend across the side edges of the pad 10 and both surfaces. These grooves 13 render region B flexible both sidewards and front to rearwards.
  • region C which is of more pronounced curvature and is where the insert 12 is located.
  • the insert 12 fits into a recess in the front surface of the pad 10, i.e. the surface shown in Fig. 2, which in use will contact a user's body, but at the inner edge margin (as in use) it extends through to the rear surface also (see Figs.4 & 5).
  • the insert surface matches the contours of the pad, i.e. is flush with the adjacent surface.
  • the insert 12 itself is formed with further more widely spaced transverse grooves 14.
  • the adjoining narrow end region D is of reduced thickness and is intended for attachment of a strap connector or buckle or the like.
  • the pad 10 is produced by moulding, with all its above-described three dimensional contouring, and both the insert 12 and any strap connector in region D may be integrally formed or connected, respectively, in the moulding process. Otherwise they may be separately fixed after moulding of the main part e.g. by gluing.
  • Fig. 1 it will be noted that in use two such pads 10, 20 are joined together symmetrically. Firstly, however, they are covered by fabric, which may be adhered therearound.
  • the broad end regions A of the pads 10, 20 are joined by central webbing 15 (alternatively by a transverse plate on which they may be mounted) and mounted by sliders (not shown) on respective vertical frame bars 21, which constitute a supportive frame for the fabric sack 22. As shown, the surfaces of the pads 10, 20 which carry the inserts 12 face rearwards, towards the back of a user.
  • Webbing 18 is attached longitudinally of the pads 10, 20, (indeed it may also be integrally connected in the moulding process) to complete the harness.
  • the webbing 18 provides shoulder straps 23, extending from buckles 24 fixed to the end region D, top straps 25 and height adjustment straps 25 for use in sliding the scapular pad regions A down the bars 21 when the sack is "in situ" in a users back to the position of greatest comfort.
  • the rucksack also includes a central lumbar pad 27, hip pads 28 and a hip belt 29.
  • the flexible grooved region B bends over and contacts the rear shoulder region of the user, and is able to adapt comfortably thereto without wrinkling.
  • the insert 12 which is of softer material contacts the front shoulder and chest region of the user and reduces pressure loading, improves comfort, in this area.
  • the top straps 25 are adjustable in the position of their take-off points from the respective pads 10, 20 by virtue of buckles 16, which are slidably adjustable in position along floating portions 17 of the webbing 18.
  • the top straps 25 are also adjustable in length.
  • Fig. 6 shows an alternative embodiment of pad 30, which along with a corresponding symmetrically formed pad (not shown) could be used in place of pads 10 or 20 in the rucksack of Fig. 1.
  • This pad is also moulded of closed cell foamed plastics material, such as polyethylene, but is formed in the moulding process with inherent front to rear curvature so as to be better adapted to fit over the shoulder of a user. Of course, some additional curvature in use to fit precisely to the shoulder is to be expected.
  • this pad 30 consists of only three regions E, F and G. Region E is a broad end region corresponding to region A of the first embodiment, and region G is a narrow end region corresponding to region D of the first embodiment.
  • Region F extends between the two (E & G) and is curved in three dimensions - i.e. sidewards and front to rear as well as having grooves 34 in its surface facing inwards of the front to rear curvature.
  • the grooves 34 do not extend across the side edges of the pad or over the other surface - but those features could be provided in other embodiments where additional flexibility is desirable.
  • a softer/lower density insert is not shown, but could advantageously be provided.
  • Fig. 7 shows some variations : 7 a as in Fig. 1 where the pads are joined and are vertically adjustable, 7 b where the pads are independently mounted for vertical adjustment, and 7 c where the pads are independently mounted for horizontal and angular adjustment (for fitting different user shoulder widths and allowing for harness angle adjustment).
  • the pads could also be fixed in permanent positions on the rear of rucksacks, or removably attached in adjustable or non-adjustable manner.
