Description

  The present invention relates to a rucksack (or backpack) that is used, for example, to transport luggage when a hiker is walking. More specifically, the present invention relates to a rucksack configured to provide a ventilation gap between a user's back and a rucksack when the user is carrying the back.

  A conventional rucksack is provided on the back attachment system that is carried by the user, and the back attachment device that is used to store a load transported by the user, and is usually a flexible enclosure. It has. A back-mounted device typically includes a pair of shoulder straps and a hip belt. Known rucksacks are usually provided with a frame that supports the back wall of the storage section, which is provided with a back-mounted device. The upper end of the shoulder strap is attached to the upper part or the vicinity of the frame, and the hip belt is attached to the lower part or the vicinity. By providing a scapular pad on the top for attaching a strap, comfort can be enhanced, as well as a hip belt is generally passed in between. In known rucksacks, the upper end of the shoulder strap or scapula pad to be attached is adjusted up and down on the frame relative to the hip belt, changing the length of the back adjustment system, depending on the length of the user's back Some fit as you get closer.

  It is desirable to keep the center of gravity loaded on the luggage transported in the rucksack storage part as close as possible to the user's back. However, when the back surface of the storage unit leans on or very close to the user's back, it causes excessive sweat on the user's back, causing discomfort.

  Many structures, such as the Berghaus “Freeflow” structure, have been developed to create a ventilation gap between the user's back and the back of the storage. These structures typically include a resilient vertical frame member that supports the back of the rucksack housing, and either side of the back is elastic connecting the upper and lower ends of the vertical frame member. An air-permeable mesh structure panel with no tension holds the bow shape under tension. In such a structure, the mesh panel contacts the wearer's back while the bow shape of the frame member creates a breathable gap so that air can circulate through it. Hold the back away from the user's back.

  In particular, since the mesh panel that contacts the user's back allows air to pass, such a structure helps keep the user's back cool and can significantly reduce sweat. However, the bow shape of the frame means that the storage part is separated from the user's back by a sufficient distance. This disadvantageously causes the center of gravity loaded on the luggage in the storage unit to move further away from the user, affecting the internal space of the storage unit.

  Some rucksacks attempt to address this problem by replacing them with an arcuate frame member under tension to maintain a more uniform gap between the storage and the user's back. This frame member is formed in advance and includes a rigid frame member formed so as to exactly match the shape of the user's back. An example is described in German Patent 2,413,948. This keeps the center of gravity close to the user's back. However, the rigid frame members used in such rucksacks tend to be expensive because they must be constructed of a strong material rather than a lightweight material, and therefore generally “expensive” "Applicable to rucksacks and not widely adopted.

  A further disadvantage of known rucksacks with a ventilation structure on the back is that they tend to fix the back length, so that the fit has backs of various lengths It cannot be optimized for the user. In an adjustable manner, the back length can be adjusted by attaching the scapular pad to the frame or back of the pack, the air gap between the back of the rucksack storage and the user's back. Tend to sacrifice.

  In general terms, the present invention aims to provide a back structure for a rucksack provided with a combination of ventilation intervals and an adjustable back length. A preferred embodiment of the rucksack includes an air gap, and one or more mesh fibers that span the air gap from the top to the bottom, and a scapula pad that is adjustably provided on the one or more mesh fibers. Have. With this configuration, the back gap is achieved by adjusting the position of the scapula pad up and down on the fiber so that the air gap is not sacrificed.

  Some embodiments of the present invention use a pre-formed frame to form a thin air gap. In a preferred embodiment, the frame is a pre-formed panel that extends across the full width (or close to the full width) of the back of the storage. Such panels can be made relatively inexpensively from plastic materials, for example by molding. This concept can be used on its own (ie without an adjustable back structure) and is not expensive, but it benefits from a thin air gap: the interior space of the rucksack compartment and the user Provide a pack that does not affect the center of gravity near the back of the back.

In the first aspect, the present invention provides:
A storage unit for storing the packages to be transported;
A frame attached to the back of the storage and formed to hold the back of the storage away from the user's back to create an air gap;
One or more web elements extending from the top to the bottom of the frame across the air gap;
A pair having an upper end adjustably provided on the web element so as to be adjustable along the web element between a first position close to the top of the frame and a second position close to the bottom of the frame. With shoulder straps,
A backpack characterized by comprising:

  It is preferable that the upper end of the shoulder strap is provided on the web element through a panel that can engage with the web element and slide the web element upward and downward. The upper end of the shoulder strap can be attached to or formed integrally with the sliding panel. The sliding panel is one or more scapular pads or may incorporate it.

  The rucksack also typically includes a hip belt provided in the lower end region of the frame. An adjuster located at the upper end of the shoulder strap relative to the hip belt adjusts the back length of the rucksack.

  By providing an adjustable shoulder strap on the web element that spans the air gap, the air gap between the web element and the back of the compartment when the upper end of the strap and any, eg, scapular pad, is adjusted The upper end of the strap and any, for example, scapula pads, are fixed so that they do not need to be affected. In this way, the back length of the rucksack can be adjusted without imposing a significant sacrifice in the air gap and the breathability provided thereby.

  Fixing means are preferably provided for fixing the shoulder strap in the first position, alternatively in the second position. It is preferable that the shoulder strap can be fixed at one or more positions between the first position and the second position. The securing means may be, for example, a clip, a stop or a selectively releasable securing element. In embodiments, the securing means is a complementary securing connected to two or more securing jigs on the back of the storage and a shoulder strap selectively engageable with one of the securing jigs on the back. And a jig. To adjust the back length, the complementary fixing jig on the shoulder strap can be removed from one fixing jig on the back of the storage, and the strap can be connected to the remaining fixing jig on the back. The web element is adjusted up and down to a corresponding new position, at which time the shoulder strap fixture is engaged with the back fixture. The fixing jig on the back surface may be formed with a complementary fixing jig connected to a shoulder strap as a hook, and vice versa.

  The or each web element is preferably composed of an air permeable mesh structure. In a preferred embodiment, one provided two parallel web elements facing one side of the rucksack and spaced apart from each other in the lateral direction.

  The frame is formed by an elastic frame member that is bent in a curved shape to maintain an air gap and is held under tension by a web element. More preferably, however, the frame is pre-formed to define the air gap. A preferred embodiment of the features of the present invention employs a pre-formed frame according to the second aspect of the invention below.

In the second aspect, the present invention provides:
A back-mounted device worn by the user,
Storing the goods to be transported, and a storage part provided in the back mounting device;
A frame attached to the back of the storage and formed to hold the back of the storage away from the user's back to create an air gap;
With
A rucksack is provided wherein the frame has a pre-formed panel that preferably extends substantially across the full width of the back of the storage.

  A back-mounted device generally includes a pair of shoulder straps. The shoulder strap preferably includes a hip belt.

  The panel may be pre-formed during manufacturing to have a shape to create the air gap, thereby further bending and tensioning the assembled rucksack to create the desired spacing. It is not necessary to be placed in a state where By using a pre-formed panel in this way, the air gap can indeed be maintained over the entire width of the rucksack. The air gap may be thin with substantially the same depth, preferably over most of the height and width of the back of the rucksack. As a result, the center of gravity of the load in the storage unit is held close to the user's back, and the influence of the frame on the internal space of the storage unit is minimized.

  The pre-formed panel may be formed from any suitable material, but is preferably molded from a plastic material. Thereby, it replaces with the metal rod already bent beforehand used, and realizes that it is light weight and is cheaper.

  The pre-formed panel preferably includes a central area that is generally flat, and a lower portion that is folded so as to protrude forward (toward the user's back) from the central area. The panel may also include an upper portion that folds so as to protrude forward from the panel. The area protruding forward in the lower part is intended to be adjacent to the lower waist of the user. When the rucksack has a hip belt, the hip belt may be provided in a lower protruding region of the frame. The upper end of the shoulder strap may be provided at a fixed position close to the upper projecting area of the frame, and preferably the lower end of the projecting area, but in a more preferred embodiment, the shoulder strap is described later. Can be adjusted.

  The flat central area of the pre-formed panel may be at least 30% of the vertical length of the panel and may be 40%, 50% or more of the vertical height of the panel. Preferably, the upper and lower portions of the panel protrude at least 2 cm forward from the central area (this is close to the resulting air gap depth), and more preferably about 3 cm.

  In other embodiments, the pre-formed panel may have a continuously concave curved shape, or other suitable shape, to create the desired air gap. In general, the air gap is at least 2 cm deep, more preferably at least 3 cm, but the air gap is not formed too deep (ie, it is 10 cm in height, more preferably 5 cm).

  One or more air permeable mesh elements may extend generally vertically across the air gap. Such elements are intended to lean against the user's back and help maintain the spacing between the user's back created by the frame shape and the back of the receptacle.

  The shoulder strap is preferably adjustable with respect to the frame and adjusts the back length of the rucksack. The upper end of the shoulder strap is, for example, provided on a pre-formed panel (that is, the end of the panel) and can be adjusted. In a preferred embodiment of this feature, the shoulder strap can be adjusted to the first feature described above.

In a third aspect, the present invention provides:
A back-mounted device worn by the user,
Storing the goods to be transported, and a storage part provided in the back mounting device;
A frame attached to the back of the storage and formed to hold the back of the storage away from the user's back to create an air gap;
With
A pair having an upper end adjustably provided on the rucksack so that the back-mounted device can adjust between a first position close to the top of the frame and a second position close to the bottom of the frame. The present invention provides a rucksack characterized by comprising a shoulder strap.

  Embodiments will be described in detail with reference to the accompanying drawings.

The main concept included in the back device of the rucksack which concerns on embodiment of this invention is shown roughly. It is a front view of the back (namely, the side which opposes a user when carrying the back) of the rucksack which concerns on embodiment of this invention. It is a front view of the mounting part to the shoulder of the rucksack of FIG. It is a rear view of the mounting part to the shoulder of the rucksack of FIG. FIG. 3 is a partial front view of the back according to the rucksack of FIG. 2 with the shoulder mounting portion removed. 2 is a side cross-section (along line AA in FIG. 2) of a pre-formed panel of molded plastic that forms the frame of the rucksack of FIG. 2 (“S / S end” is the top or shoulder strap). End, "H / B end" is the lower end of the frame or the end of the hipbelt).

  FIG. 1 schematically illustrates the main concepts and components shown in the other figures and embodied in a general rucksack described below. The rucksack includes a pre-formed frame 10 which is a molded plastic panel in this example. The frame 10 may support the back surface of the load conveyed to the storage portion of the rucksack and may be held in a pocket on the back surface. The frame 10 extends substantially across the entire width of the back of the rucksack. The frame has a flat central area 12 and an upper part 14 and a lower part 16 projecting forward from this central area (ie towards the user's back).

  Two air permeable mesh fiber elements 18 extend from the top 14 of the frame to the bottom 16 of the frame. Due to the advantage that the frame 10 has a pre-shaped shape, the mesh element 18 is arranged in front of the central area 12 of the frame 10. When the rucksack is on the user's back, the mesh element 18 leans against the user's back and the central region 12 of the frame 10 holds the back of the rucksack storage away from the user's back. An air gap 20 (corresponding to the back of the rucksack) between the mesh element 18 and the central area 12 of the frame allows air to circulate between the user's back and the backpack storage. To do.

  The upper ends 22 of the two shoulder straps 24 are fixed to a shoulder blade pad 26. The scapula pad 26 is disposed on the two mesh elements 18 and can slide up and down so that the position of the upper end 22 of the strap 24 is more or less spaced from the lower portion 16 of the frame 10. The back length of the rucksack can be adjusted effectively.

  2 to 5 illustrate a rucksack that includes the conceptual and structural features schematically illustrated in FIG. Thus, referring to FIG. 2, the rucksack is held in a pocket on the back 30 of the rucksack and has a frame (not shown) which is a pre-molded molded plastic panel.

  Two generally parallel air permeable mesh structural strips 18 (best shown in FIG. 5) extend from the top to the bottom of the back 30 and are formed by the shape that the frame imparts to the back 30. Spans a breathable air gap.

  The rucksack includes a hip belt 32 at the lower end of the back surface 30 and a mounting structure 34 on the shoulder toward the upper end of the back surface 30. The shoulder mounting structure 34 includes a scapula pad 26 and two shoulder straps 24. The scapula pad 26 is slidably disposed on the mesh strip 18 that allows placement of the scapula pad 26 so that the upper end of the shoulder strap 24 is adjusted relative to the hip belt 32 and the rucksack. Change the back length of.

  More particularly, with particular reference to FIGS. 3-5, the posterior side of the scapula pad 26 (see FIG. 4) has two fabric pieces 40, one attached to either side of the pad 26. Yes. Since these cloth pieces are attached only to the rear side edge of the scapula pad 26, the cloth pieces form a tunnel on the rear side of the scapula pad 26, and the individual pieces penetrate through the tunnel. A mesh strip 18 can extend from the top to the bottom. Thereby, the scapula pad is held on the mesh strip 18 and can slide freely up and down.

  The scapula pad 26 can be secured in any of a number of locations along the mesh strip 18 by hooks or clasps 50 of the scapula pad 26 and is provided on the back 30 of the rucksack storage. The selected one of the set of loops 52 can be selectively engaged. In this illustration, a hook 50 is attached to the back side of the scapular pad 26 by a mesh loop 56 and is hanging.

  In this example, as best shown in FIG. 5, there are five loops that allow for five levels of position adjustment for the scapular pad 26, corresponding to a back length adjustable to five levels for the rucksack. ing. The loop 52 is formed from a strip of fabric 54 that is fixed to the back surface 30 vertically away from the horizontal region so that between the fixed regions the fabric protrudes from the back surface 30 to form the loop 52. Yes.

  To adjust the position of the scapula pad 26, the hook 50 now disengages from the engaged loop 52, and the scapula pad slides up (lowers) the mesh strip 18 to the desired new position, at which position The hook 50 can engage with the remaining loop 52.

  To assist in supporting the shoulder strap at the desired location, a length adjustable high tension strap 58 is the most possible for the shoulder blade pad 26 with the middle portion of each shoulder strap 24 at the back of the rucksack. Connect above the high position. These straps 58 can be extended when the scapula pad 26 moves down the back of the rucksack (to reduce the length of the back), and the scapula pad 26 moves up the back of the rucksack. When moving to (to increase the length of the back) can be shortened.

  In the illustrated example, the length of the shoulder strap itself can also be adjusted by using the adjuster 60 at the lower end of each strap so that the chest strap 62 can be accurately placed on the shoulder strap shoulder during use. It is provided to help you keep it on the board.

  FIG. 6 shows a side cross-section of a molded plastic plate or panel used as a rucksack frame. The panel has a flat central area 12 and an upper part 14 and a lower part 16 projecting about 3 cm forward from the central area 10 (ie towards the user's back) to form an air gap 20. In the transition between the central area 12 and the upper part 14, the panel folds along the first fold 70, and then continues with the straight area 72 being folded a second time at the second fold 74, so that the frontmost of the panel Elongation to is prescribed. The lower part 16 is formed in the same manner. The panel spans the entire width and has the same area, thereby generally corresponding to the width of the back of the rucksack.

  Those skilled in the art will appreciate that various modifications can be made to the specifically described embodiments without departing from the scope of the present invention.
