Definitions

  • the present invention relates to a backpack intended, although not exclusively, for mountaineering and all hikes whether pedestrian or on skis.
  • the adjustment of the straps must make it possible to adapt the bag to the morphology of each individual.
  • a backpack usually has a drawstring to close the bag and a flap with one or two tightening straps.
  • the speed of closing poses a problem: you must always tighten the straps after taking something out of the bag.
  • the first characteristic of this bag is to present two shells (one rigid, the other semi-rigid) made of plastic materials. These two shells fit into each other and are each articulated around a point located in the low position on each side of the bag. This articulation allows a total opening of the bag at an angle of 180 °. Thus, accessibility is optimal in all parts of the bag.
  • Each of the two shells has a very specific function.
  • the outer shell is used to store the material intended to be worn. It is semi-rigid to facilitate the storage of bulky effects.
  • the rigid inner shell which will be called the back shell, serves as a closing cover. This back cover is the centerpiece of the bag. It incorporates a new carrying system.
  • the design of a bag in two separate nestable parts implies for the user a new way of "making his bag".
  • the bag is no longer loaded from above but flat, the outer shell being placed on the ground.
  • the use of two shells also modifies the usual principle of closing backpacks, namely, drawstring and tightening straps: a single point of closure is sufficient to effectively connect and keep the two shells closed. This closing point is located on the upper part of the back shell.
  • the opening and closing of the bag is instantaneous and is carried out with one hand.
  • the very use of plastics makes the bag weatherproof. This represents a significant advantage and avoids "moisture overload" during rain.
  • the second characteristic of this bag lies in the fact that a rigid back shell allows effective ventilation of the wearer's back.
  • the principle is simple: the use of plastic materials makes it possible to obtain a rigid shell with accentuated concavity both on a longitudinal and transverse plane so that there is no direct contact between plastic shell and back of the wearer.
  • a longitudinal concavity is created so that the bag follows the shape of the back of an individual in the folded back position. The bag must be able to "stick" to the individual in some specific situations such as climbing.
  • This longitudinal concavity is studied as follows: - support of the lower part of the back shell on the last lumbar vertebrae - support of the upper part on the shoulder blades - absence of contact of the bag between the shoulder blades and the last lumbar vertebrae (except in the climbing position).
  • this concavity does not sufficiently limit the surfaces of the bag in direct contact with the back of the wearer. It is therefore necessary to create another concavity in the transverse direction.
  • the purpose of the transverse concavity is to promote the circulation of air between the back of the wearer and the back of the bag and thus to reduce very significantly the usual perspiration. Means are necessary to maintain a certain distance and thus avoid any annoying direct contact between back shell and carrier.
  • a back cushion adjustable in lateral tension as well as in longitudinal position, stretched on either side of the transverse concavity
  • a floating hip belt known per se, but adjustable in lateral tension and also taut on either side of the transverse concavity.
  • the function of the small back cushion is to increase air circulation and promote the evacuation of perspiration. It consists of two small longitudinal foam beads delimiting a central channel. This channel avoids direct support of the cushion and therefore of the bag, on the dorsal vertebrae.
  • This cushion is adjustable in lateral tension for optimal use of the bag both when hiking and climbing. In the hiking position, the cushion is stretched to the maximum for better ventilation. Conversely, in the climbing position, the cushion is relaxed so that the bag can "follow" the movements of the climber.
  • the bag can thus "stick" to its wearer for better carrying accuracy and greater progression security.
  • This lateral tension adjustment can be done with the backpack.
  • This setting alone is insufficient.
  • the cushion must still be able to be moved longitudinally to adapt to a height adjustment of the carrying straps.
  • the floating hip belt also promotes air circulation between the wearer and his bag. The originality of this belt is that it can be stretched effectively on the back shell in the hiking position. In the climbing position, it can be relaxed so that the bag can "stick” to the lower back. In both positions, the maintenance of the bag at hip level remains optimal.
  • the third feature of this bag is related to the speed and ease of adjustment of the straps.
  • the back shell is fitted with an adjustment system to which "two" new design carrying straps are attached. It is no longer two separate straps that are attached to the bag as usual, but a single piece forming two straps. This single removable piece has in its middle a narrower part intended to connect a passable secured to the adjustment system. The two ends of this "strap" are attached, as usual, to the base of the bag where they can be adjusted in length.
  • the strap adjustment system allows, and this is already known in itself, to adjust the height of a single point of attachment of the straps so as to best adapt to the size of the back of the wearer.
  • the originality lies in the fact that this system is integrated in the back shell in the middle of the transverse concavity and that it comprises in combination an adjustment scale and a slider provided with a single pass.
  • the adjustment scale consists of a central longitudinal channel occupying the upper half of the back shell and both sides of which have regularly spaced holes.
  • the adjustment slider is made up of a rectangular locking block fitted with four self-locking bolts distributed at the four corners and a loop fixed in the upper part. This cursor moves longitudinally inside the channel.
  • the locking block can be released and moved by pressing two fingers on two slides. The pressure must be maintained during movement because the release of the two slides instantly blocks the cursor.
  • the adjustment of the shoulder straps is completed by two "charge reminder" cords.
  • this bag consists of two shells: a rigid back shell (2) and a semi-rigid outer shell (3). These two shells fit into each other and are interconnected by a point of articulation (4) located in the lower position on each side of the bag. They are kept closed by a single closing point (5) known per se, located in the high position on the back shell.
  • the rigid back shell (2) has two clearly differentiated concavities, one in the longitudinal direction (6), the other in the transverse direction (7).
  • This transverse concavity is limited, on either side of the shell, by two small convexities (8).
  • the center of the transverse concavity (7) is cut longitudinally at the height of the dorsal vertebrae by a central channel (9).
  • the two lateral convexities (8) are notched with horizontal ridges (10) regularly spaced on the upper half of the back shell (2).
  • Two small grooves (11) are located on either side of the two convexities, perpendicular to the horizontal ridges (10).
  • On the transverse concavity (7) are stretched, on the one hand in the upper part a back cushion (12) at the level of the shoulder blades, on the other hand in the lower part a floating hip belt (13).
  • the back cushion (12) consists of two foam beads separated by a central longitudinal channel (14). This cushion forms a rectangle about fifteen centimeters high by thirty centimeters wide. At each corner of this rectangle is attached a tension cord (15). These four cords are housed in the horizontal streaks (10). At their end is fixed a blocker (16) known per se, which is housed in a small longitudinal groove (11) arranged on the external flank of each of the two lateral convexities (8). The cords are relaxed by simply pressing the blocker (16). Conversely, the cushion tension is obtained by pulling on the cords.
  • the floating hip belt (13) known per se comprises in combination two tightening loops (17) fixed in the low position on each side of the back shell, and four straps (18) sewn symmetrically at different levels on the outside of hip belt.
  • the originality of this hip belt (13) is to present two straps sewn symmetrically on the back (18a), and two others sewn on the sides (18b).
  • the hip belt detaches from the bag: the bag is then moved away from the wearer and ventilation is optimal (hiking position).
  • the side straps (18b) are tight and the rear straps (18a) are detached, the belt is pressed against the bag: the bag is then in "direct engagement" with the wearer (climbing position).
  • connection of the bag to the back of the wearer is ensured as usual by two straps (19).
  • the originality lies in the mode of connection of these "two” straps with the back shell (2).
  • This connection takes place between the back cushion (12) and the back shell (2) by means of "two" straps of new design (19) and an adjustment slider (22).
  • the two usual suspenders consist of a single piece (19) having in its middle a narrower part (20a). On either side of this narrow part is a very wide part (20b) constituting the two carrying straps. These wide parts (20b) are supported on the shoulders. They are wider than usual at shoulder level for better carrying comfort and have a straight side (20c) and a convexo-concave side (20d) to avoid discomfort under the armpits.
  • This unique piece is gradually refined at its ends.
  • This unique piece forming two carrying straps is attached as follows to the back shell.
  • the narrow part (20a) is folded in half in the middle and passes through a pass (21) secured to an adjustment slider (22) housed in the central longitudinal channel (9) of the back shell.
  • the two ends of the single piece (19) then pass through the loop emerging from the passer-by (21) to form a hanging knot and are fixed, as usual, at the base of the bag on the back shell.
  • a hooking node allows immediate adaptation of the "straps" to the various widths of shoulders and neck.
  • the "two” straps (19) are each provided with a "load reminder” cord (23) These two cords are permanently attached to the top of the back shell but are adjustable on the straps.
  • the "load reminder” cord (23) enters the strap at the upper third (24) and exits at the lower third (25) where it passes through a blocker (26).
  • the adjustment slider (22) moves along a scale (27) formed by the two sides of the central longitudinal channel (9). These two sides have regularly spaced holes.
  • the slider consists of a locking block (28) and four self-locking pins (29). These bolts are actuated by two slides (30). A pressure of the two slides causes the four bolts (29) to retract inside the locking block (28) and thus releases the mechanism which can then slide freely along the ladder (27). A release of the sliders (30) immediately blocks the cursor (22). Two springs (31) hold the four bolts in the locked position.
  • the locking block (28) has in its upper part the pass (21) ensuring the fixing of the single piece (19).
  • this backpack combines the following essential advantages: - better ventilation of the back due to the use of a rigid back shell (2) having a longitudinal (6) and transverse (7) concavity on which are stretched a back cushion (12) and a floating hip belt ( 13) - increased carrying comfort both when hiking and climbing due to the possibility of adjusting the lateral tension of the back cushion (12) and the floating hip belt (13) - optimal accessibility inside the bag due to a design in two separate shells, a rigid back shell (2) and a semi-rigid outer shell (3), articulated around a point (4) located in low position on either side of the bag - extreme ease of closing the two shells with a single point (5).
  • One hand is enough to open and close the bag - total tightness due to the very use of plastics - a system of ultra-fast adjustment of the position in height of the straps on the back shell thus allowing the adaptation of the bag to the morphology of each individual.
  • Two fingers are enough to move the self-locking adjustment slider (22).
  • This adjustment system is integrated in the back shell so as not to disturb the wearer -
  • a single interchangeable piece (19) forming two straps and adapting, by its very attachment to a single pass (21), to all widths of shoulders and neck.
