Description

Organization of human body self adaptation and meet the load distribution band of ergonomics

Background technology

For a long time, the human or animal uses band and harness (harnesses) always when carrying or mobile big and/or heavy load.Usually be attributed to the weight of load, the carrying heavy load can cause sense of discomfort usually, yet band or harness can be caused this sense of discomfort by censure equally.For example, the band on the normally used musette bag of students or the knapsack is introduced basic not improvement so far since such bag is initial.And moving around of load and traditional backpack strip may cause pulling, fash and unnecessary damage.Yet students can be complained the weight of entrained article usually, and does not recognize that band or harness are only the actual cause that causes their injury.The case of repetitive strain injury thus, (RSI) and musculoskeletal disorder (MSD) is also continuing rising.

One of reason that existing carrying band and harness bring sense of discomfort is that they are to make with the material of rigidity and inflexibility, and are not limited to leather and fibre bundle.When carrying load, the lower surface area of band can make band rein in the incarnation, and the material of band is then along with kinetic vibration produces friction.Thus, band meeting abrasion user's skin is especially when the user passes through the landform of rugged or fluctuating.Thus, when carrying load surpassed a period of time, band can allow the people more and more painful and may cause damage.When band produced sense of discomfort, people can adjust, and the sense of discomfort of animal could be found by the people in the time of can seeing up to injury.

By better material, such as the US5 of Heckerman, 143, No. 266 illustrative neoprene foams of patent have made progress to improve the design of band.Yet slowing down simply that load produces repeat to push is not sufficient to reduce the possibility that produces injury, because load is distributed in the whole injury Yi Fa district as downward pressure usually.

Summary of the invention

According to an aspect of the present invention, band or harness can provide better power to distribute by cut portion.In a kind of structure, cut portion is placed in the middle and along the band longitudinal extension, but stops before the edge.Cut portion can provide crooked outward flange, this outward flange is the narrowest in order to form parallel member effectively in centre, even when the characteristics of human body that is pressed to such as acromion, cucullaris, shoulder and neck area, this parallel member also is convenient to self adaptation and is improved compliance.The band system can redirect dynamic load and shift from the responsive N﹠M of direct compressing thus.This redirects and can ease off the pressure and auxiliary recovery in a plurality of fields, including but not limited to: repetitive strain injury (RSI), musculoskeletal disorder (MSD), neuromuscular disorder, orthopedics injuries, fatigue and common sense of discomfort.This cut portion can also promote gas permeability, in order to discharge the probability of moisture and reduction fash and other potential medical condition.

The shortcoming of the band that some are previous and harness design is, causes skew and tendency toward sliding because dynamic force impels band in one plane to slide, and is such the spitting image of sliding at borneol.This slip impels the user to regulate load and weight location on the health usually, and resets the supporting way of band on their shoulder.Some embodiments of the present invention have solved the problem of sliding by this way: form two or more planes by the cut portion passage, reduce the towing of leading edge thus by minimizing because of the integral surface tension force of the push-pull effort generation of directionality.

According to a further aspect in the invention, the revolving part at place, the end of band and/or harness can form joint, and this joint permission extension band is independent of main member and moves.This independence movement can help to slow down tension force and material friction, and adding increases loose sense and reduce tension force, thereby the pivotal action by the imitation human synovial rather than band are reined in into and given the user the more dynamically free degree among the user.This revolving part can also increase the stability of main stationary member.

According to another aspect of the invention, by improving perceived value and overall usability, can prolong the service life of band.Such band or harness can be integrated in, are applicable to or add to following application, and described application is including, but not limited to the similar carrying product of: underwear, knapsack, binoculars, sports goods, weapon, media record equipment, digital equipment, courier's bag, golf bag, bag, wallet, clamping plate, parachute, animal harness, remote control unit, Medical Devices, handwriting pad, computer, computer equipment, moving belt and other.Further feature can comprise modularizing member, as: the connector of screw thread, clip and other type.

Additional or the integration of some embodiments of the present invention is characterised in that the web (webbing) of low friction or the use of material, by reducing pulling and increasing user's comfort by reducing material texture, the web of low friction or material help band to move better.This material can also helpers moves and reduces Bei Gou Pan or winding.Alternatively, various materials, streak line otch and enhancing position can be used to improve durability, keep the integrality of major function of the present invention simultaneously.
