Description
Technical field
The present invention relates to a kind of Load-Carrying Equipment that supplies uses load is transferred to the load transition zone of user's buttocks from Load-Carrying Equipment.
Background technology
When proposing haversack (one type Load-Carrying Equipment) the earliest, unique to be used for it is supported on user's device on one's body be shoulder belt.This means that the load of haversack only acts on user's the shoulder, cause its center of gravity to move backward.In order to compensate this point, when the back haversack, the user need turn forward.With the inclination attitude walking is uncomfortable and tiring, and therefore, the user is easy fatigue more, and this can cause damage and can not pass required separation distance.
In order to overcome the above problems, proposed the weight of load more is evenly distributed in user's haversack on one's body.A kind of mode that realizes this effect is to introduce the buttocks fin.These are the hard filler elements that in upper/lower positions, are attached to the framework of haversack rigidly, and in said position, said hard filler element in use will be positioned on the Background Region of user's buttocks.Like this, the load of haversack is transferred to user's two shoulders and the Background Region of buttocks through this framework.Because buttocks is the point that is in the below, so this layout can make user's steadily of centre of gravity.
Though rigid tab provides the part solution to the load branch problem,, rigid tab can brought shortcoming aspect user's the comfortableness.In addition, everyone pelvic dimensions is different; Regard pelvis as truncated cone, the angle of everyone truncated cone side and the girth of truncated cone are different, particularly between the masculinity and femininity.Therefore, rigid fin is inappropriate for many pelvic dimensions.
For head it off, the flexible waistband of filler has been proposed.Compare with rigid tab, flexible stern band provides improved comfortableness, but because it lacks rigid mount, so its transferring load effectively.
A kind of improved stern band is disclosed in US 6536641; This stern band has two rigid plate, one along the length of waistband with either side that haversack is connected on extend.And, EP0570192 disclose a kind of be installed in either side that haversack is connected on waistband in the rigid plastics net.
Therefore, need be to user's buttocks transferring load and provide to the user and to seek balance between the comfortableness effectively.Usually these are thought two opposite demands, because the increase of comfortableness means the increase that the stern band is flexible usually, this can cause reducing of load transfer ability, and vice versa.
Summary of the invention
The present invention be intended to through provide a kind of concerning the user the load transition zone of comfortable and suitable pelvic dimensions in a big way; Provide the increased dynamic load of rear portion and front area to shift simultaneously, satisfied the opposite demand of the load transfer of the comfortableness thought and enhancing from Load-Carrying Equipment to user's buttocks.
Therefore, in first aspect of the present invention, provide a kind of Load-Carrying Equipment that supplies to use so that load is transferred to the load transition zone of user's buttocks from this equipment, this load transition zone has:
A plurality of load transfer elements along the strip length location;
Each load transfer element is connected through the swivel joint load transfer element adjacent with at least one, and swivel joint limits the rotation that is transverse to strip length, surrounds user's health to allow the load transition zone.
The load transfer element provides the pay(useful) load in the zone from Load-Carrying Equipment to user's buttocks to shift; In use; The position alignment of this zone and load transfer element, swivel joint allows the necessary amount of each load transfer element rotation simultaneously, to be fit to the size of user's pelvis.This structure allows the load transition zone to have the belt shape structure of certain limit, is fit to various user's body shapes to allow the load transition zone.The setting of swivel joint provides the freedom of motion, rather than through making the load transfer element have the freedom that big flexibility provides motion.This means that the load from Load-Carrying Equipment to user's buttocks is shifted and can not be compromised.
Disclosed stern band does not have the load transfer element that is connected through swivel joint among US 6536641 and the EP 0570192.In fact, the band of prior art does not have like any type of hinge portion provided by the present invention.On the contrary, the band of prior art provides known hinges.That is, load transfer element itself has flexibility and adapts to the shape of user's health.Thereby the load transfer element of the band of prior art need be more soft than load transfer element of the present invention, that is, it need have the hardness that reduces.The reducing of the hardness of load transfer element mean, it can't realize that the load that is realized with the present invention shifts the load of par and shift.In addition, compare with the present invention, the comfortableness of the load transition zone of prior art reduces, and the flexibility of load transfer element shifts to realize comfortableness and load simultaneously because the band of prior art need be traded off.
In use, orientate the load transition zone as surround the user buttocks, thereby, according to the length of surrounding user's buttocks orientation measurement load transition zone on every side, measure its length to the securing member at band other end place from securing member with an end.When this band and Load-Carrying Equipment used together, most of load of Load-Carrying Equipment acted on the direction of the length that is transverse to the load transition zone, and therefore, the basic load direction is this direction.Horizontal direction is represented the width direction of intersecting with band.Horizontal direction maybe be vertical or maybe be not perpendicular with the length of band.Realize the load transfer with being formed load transfer element in a lateral direction with necessary hardness.Usually realize hardness with stiffener.
The load transfer element may extend to band in use with the corresponding zone of the front area of user's buttocks.Many Load-Carrying Equipments all are designed to be positioned on user's the back (Background Region).In the corresponding zone of the front area with buttocks of band, the load transfer element is provided, can allows to shift to the load of the front area of buttocks from people's back.This has reduced load, and has reduced the stress on the lumbar region at back thus.
Preferably, the load transfer element is connected to form serpentine configuration (serpentine configuration, serpentine structure).In one embodiment, the load transfer element possibly be u shape and n shape.Preferably, the load transfer element is u shape and n shape, and it is connected to have serpentine configuration.

Advantageously, the serpentine configuration of u shape and n shape load transfer element causes the part of load transfer element to be located along the direction that is transverse to strip length.Shift from the load that the aligning on the direction of the basic load of Load-Carrying Equipment has further improved from Load-Carrying Equipment to the load transition zone on the part edge of load transfer element.
This serpentine configuration further is favourable because it is in light weight.The user can carry heavier load with Load-Carrying Equipment for a long time, therefore, to Load-Carrying Equipment and load transition zone any weight that can carry out reduce the amount that reduces the fatigue that the user experiences when carrying Load-Carrying Equipment.
This serpentine configuration also is easy to structure.This causes the simplification manufacturing of load transition zone.
Preferably, the load transfer element is made of plastics or is made of metal.
When comparing with the load transition zone of prior art, the serpentine configuration of load transfer element increases the hardness of load transition zone.In use, (through Load-Carrying Equipment) in most applications, the load of Load-Carrying Equipment will make the load transition zone with the direction in the opposite direction of load effect on twist.With reference to Figure 18, in a test, load transition zone 15 is fixed in the closing position at its shortest length place, in use will be positioned at user's buttocks ring on every side to produce.Load-Carrying Equipment 10 is placed on the flat surfaces.In the distance B that measures 10cm with will act in the opposite direction of load and on from the center of load transition zone perpendicular to the direction of load transition zone.Then, be hooked on the load transition zone or pass wherein with the spring scale of calibration, simultaneously Load-Carrying Equipment is kept fixing, the extension spring scale is so that the distance of load transition zone distortion 10cm.Load transition zone of the present invention has the torsional loading (that is, causing the required load of 10cm distortion) greater than 4kg.The torsional loading of the load transition zone of being tested of prior art is lower than 3kg.Preferred implementation of the present invention will have the torsional loading greater than 3kg.
Preferably, will be with Load-Carrying Equipment with link member and be connected.Can link member be positioned at the center of band.In this situation, the load transfer element is positioned on every side of link member.In the situation of load transfer element, also serpentine configuration is positioned on every side of link member with serpentine configuration.
In addition, can make or arrange the load transfer element of serpentine configuration like this, make that the interval between the cross-section part of load transfer element separates along serpentine configuration (or along band) equably.The even interval of cross-section part causes uniformly distributed load around the load transition zone.In use, load on even distribution around user's buttocks and avoided the high capacity in the lumbar region at back, this is useful with limiting aspect tired to the user improving comfortableness.
The part that is transverse to the serpentine configuration of strip length possibly have the central axis that overlaps with the rotation of swivel joint.This layout advantageously allows to use simple swivel joint, for example pivot fitting.
Swivel joint possibly be the pivot fitting that is used for snakelike and non-serpentine configuration.Randomly, form pivot fitting with male connector and recessed connector.Perhaps, use two male connectors that connect by sleeve to form pivot fitting.The male-female connector of swivel joint and two male connector structures all form durable joint.Can in load transfer element itself, form connector.This advantageously allows to change like a cork the load transfer element.
The load transition zone can have the plate (panel) of the length of extending the load transition zone.Can add liner to the load transition zone, with further improvement user's comfortableness.Said plate can comprise be used to filler, it possibly be a foam.Can the plate of load transfer element with the load transition zone be connected.Plate can being connected with the load transfer element along the directed part place of the direction of strip length at the load transfer element.In the situation of u shape and n shape load transfer element, this connection possibly be positioned at the bottom of u shape element and the place, top of n shape element.The user can contact swivel joint, so that easily change one of them load transfer element.Perhaps, can the load transfer element be completely contained in the plate.
For the further comfortableness of improving, preferably, the load transfer element is being transverse to the bigger distance of end extension towards the center ratio of being with towards band on the direction of strip length.In use, this structure has reduced the anterior zone of locating of user's health that the load transition zone is covered.
