연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

1. A system for carrying loads comprising: a harness;a back frame;a load base;vertical-only-free movement connecting means to connect said load base to said back frame so that said load base can move freely with respect to said back frame along one linear axis within a defined range substantially without transmitting vertical load onto said back frame and be steadily connected to said back frame in the other two linear axes and in the three rotational axes;load support and adjusting means having upper end and lower end to support said load base from below, said load supporting means is connected to said load base at a location so that when a load is attached onto said load base its center of gravity is substantially vertically above said connection point when said system is in use; andgliding means connected to the lower end of said support and adjusting means, to enable easy gliding of said system on the ground when in touch with the ground;wherein said load support and adjusting means further comprise: a first folding means to allow temporary backward rotation of said load support and adjusting means in response to bumping of said gliding means into a local protrusion on the ground, said rotation is returnable by retuning means; anda second folding means to allow folding of said load support and adjusting means upwardly to a stowing position. 2. The system of claim 1, wherein said means to connect said back frame to said load base is at least one from a list including a parallelogram and at least one sliding rail. 3. The system of claim 1, wherein said load support and adjusting means comprise at least two telescopic tubes that are adapted to glide in a fitted manner inside one another and adapted to be fixed to each other at a desired position. 4. The system of claim 1, wherein said harness comprises at least two links pivotally connected to each other to allow relative rotational movement of one link with respect to the other in a plane vertical to the ground when said system is carried by a user standing upright and parallel to said load support and adjusting means, to allow flexibility of said back frame when said user leans forward. 5. The system of claim 1, further comprising shock restraining means connected between said back frame and said load base to restrain abrupt vertical movements of said load base with respect to said back frame. 6. A method for carrying loads comprising: attaching a back frame to a load base by means allowing vertical-only-free movement of said load base with respect to said back frame within a defined range substantially without transmitting vertical load onto said back frame;supporting said load base with respect to the ground by means of an adjustable load support and gliding means, said load support is connected to said load base at a location so that when a load is attached onto said load base its center of gravity is substantially vertically above said connection point when said system is in use and wherein said adjustable load support comprises a first folding means to allow temporary backward rotation of said adjustable load support in response to bumping of said gliding means into a local protrusion on the ground, said rotation is returnable by returning means; and a second folding means to allow folding of said adjustable load support upwardly to a stowing position;loading a load onto said load base; andattaching said back frame to a back of a user by means of a harness attached to said back frame. 7. The method of claim 6 further comprising: restraining the movement of said load base with respect to back frame by means of restraining means connected between them. 8. A system for carrying loads, the system and comprising: a harness adapted to be worn by a user;a harness back frame attached to the harness and having a vertical axis;a load base comprising a base portion configured for receiving a load thereon, the base portion being oriented transversely to the vertical axis;connecting means connecting said base portion to said back frame so as to allow free movement of said base portion parallel to itself, with respect to said back frame, along the vertical axis;load support disposed under the base portion and having an upper end connected to the base portion and an opposite, lower end associated with gliding means configured for gliding when in touch with the ground, the load support being configured to provide vertical support to the base portion and while doing so to move along the vertical axis in response to the topography of the ground, causing thereby the load base to perform its corresponding movement parallel to itself along the vertical axis;wherein said load support comprises a first folding means to allow temporary backward rotation of said load support in response to bumping of said gliding means into a local protrusion on the ground, said rotation is returnable by returning means; and a second folding means to allow folding of said load support upwardly to a stowing position. 9. A system according to claim 8, wherein the load base further comprises a vertically oriented side portion holding the base portion fixed thereto to form an integral body or formed as an unitary body therewith, and said connecting means connect the side portion with the back frame so as to allow the movement of the side portion together with the base portion along the vertical axis. 10. A system according to claim 9, wherein at least a part of the side portion extends along the back frame and is disposed above the base portion. 11. A system according to claim 10, wherein the load base is configured to perform said movement between an raised position in which the load support exerts on the base portion an upward force, and a lowered position taken by the load base under the influence of gravity. 12. A system according to claim 10, wherein, in the side view of the frame, said part of the side portion extends along at least a majority of the back frame in at least one of said positions or in at least one intermediate position between the raised and the raised positions. 13.

A system according to claim 8, wherein the load support is configured for taking at least two states defined by different positions of at least the lower end of the load support relative to the base portion of the load base, at least one of said states allowing the load support to provide said vertical support to the base portion of the load base. 17. A system according to claim 16, wherein said load support has an upper portion associated with its upper end, and a lower portion associated with its lower end and movable with respect to the upper portion to bring the load support from one of said states to another. 18. A system according to claim 16, wherein said different states are defined by different positions of the lower end relative to the upper end. 19. A system according to claim 16, wherein said different states are defined by different distances between the upper and lower ends of the load support. 20.

A system according to claim 17, wherein the movable portion of the load support is configured for taking different angular positions relative to the vertical axis of the system, at least one of said positions being vertical. 22. A system according to claim 8, wherein the load support is configured to take at least one working position in which it is configured to proved said vertical support to the base portion of the load base, and a non-working, stored position at which it is prevented from providing such support. 23. A system according to claim 22, wherein in said stored position, one of the following conditions is met: the lower support is disposed below the base portion of the load base and has a shorter length than that in the working position and/or is oriented at such acute angle relative to the base portion, as to prevent the load support from contacting the ground;the load support is oriented perpendicular to the vertical axis of the system;the load support extends upwardly from the base portion of the load base; andthe load support is detached from the base portion with a possibility of being attached back thereto.
