Definitions

  • SHELTER IN THE FORM OFATENT ABSTRACT A tent, or a shelter similar to a tent, where i 60 Fi means are provided to protect the occupant, or occupants, a r mg against lightning bolts, which tent is in the form ofa Faraday [52] [1.8. CI 135/1 cage and the components constituting the cage are conduc- [51] lnt.l A45flll/00; tively connected to ground, or adapted to be connected to E04b0l/347 ground, and which generally comprises a metal frame and a [50) Field of Search 135/1; 52/2; cover that is preferably conductive for electricity and a metallic base or floor.
  • the present invention relates to tents or tent like emergency shelters. More in particular, this invention concerns a tent or tent like emergency shelter (for convenience only the expression tent will be used hereinafter), with means of protection against lightening strokes for the people using the tent.
  • a tent or tent like emergency shelter for convenience only the expression tent will be used hereinafter
  • For reduction of the step voltage gradient the potential difference over the length of an average human step
  • no adequate protection is given the people which are in the shelter, as it lacks protection against a lightening strike directly in the tent.
  • the protective devices against lightening should not however result in a substantial increase in the production cost, not cause any marked complications while setting up or dismantling the tent, as well as not be too unwieldy or heavy.
  • the tent is formed like Faraday's cage (an electrostatic screen) and the cagelike portions are in a conductive connection with or are connectable with the earth.
  • This contact requirement can be accomplished by means of extending the tent poles or frame to the ground, and/or a metallic grounding plate or also with metal litz wire and the like, so that the passage of the lightening bolt to ground at a definite point is insured.
  • the Faraday's cage can be formed in a simple manner by the tent frame. for example suitable metal parts or tubes and/or by the covering fabric.
  • a tent frame for example suitable metal parts or tubes and/or by the covering fabric.
  • a safety tent forming the Faraday cage is located inside the frame and disposed at a distance therefrom, which is electri cally connected in at least one place with the frame.
  • the frame which may also be in the form of a cage, serves alone as the conductor of the lightening bolt, which accordingly is not led over the tent cover.
  • the safety tent completely shields the user electrically and has the same electrical potential at all points. Thus the user in the interior can not receive a dangerous step voltage nor be endangered by contact with the tent cover.
  • the tent can be built to shelter one or more persons.
  • igloo is recommended as electrically especially favorable, but the invention is not limited thereto.
  • a tent of low structural height like the aforementioned igloo form, has the advantage that with it the danger of a lightening bolt as well as the danger of being crushed or turned over by a storm is diminished.
  • the invention can be utilized to advantage not only for camping tents but also for other purposes.
  • Such simple and easily assembled tents or emergency shelters can serve above all as protection against weather and lightening for those working or active in the open. as railroad personnel, telephone or electrical linemen, lumberjacks, farmers, fishermen, hunters, the military, border guards, mountain rangers, and so on.
  • a one man tent made according to the invention weighs only a few kilograms and is storable in a handy carrying case, so that it can be readily carried by one person over long distances.
  • emergency shelters of this type must not necessarily be adapted to be dismantled, as they may also be provided with a unitary frame to be set up in situ.
  • FIG. I is a perspective view of a first embodiment of a one man tent in accordance with the invention.
  • FIG. 2 shows a second embodiment of the invention with the tent cover omitted also in perspective
  • FIG. 3 shows schematically and also in perspective a third embodiment of the invention
  • FIG. 4 shows schematically a plan view of a tent cor responding to the embodiment in accordance with FIG. 3, but with the upper tent and frame parts omitted;
  • FIG. 5 shows in a perspective view of a portion ofa camping house tent with a suspended tent unit
  • FIG. 6 shows in a schematic plan view of FIG. 5 with the tent roof and other details not of interest omitted.
  • the frame Ia comprising assemblable metal tubes (see FIG. 2) for example steel or aluminum tubes, is provided with a lightening rod 2 suitably on its highest point, and in use rests upon the ground with its ground struts. Fundamentally other means for establishing a connection between the frame or tent and the ground would also be possible.
  • the frame Ia has the task of intercepting and conducting directly striking bolts of lightening and conducts their current immediately to ground so that the tent will not be touched thereby.
  • the frame la can also take on the function of a Faraday cage for lightening bolts striking in the proximity.
  • the tent 3 is so arranged, preferably hung in, that it is spaced a distance a therefrom to safeguard against jumping of a lightening bolt. Taking into consideration the strength of the usual lightening bolt, it will generally be sufficient, if this distance is a few cen timeters. It is however to be understood that the invention is not limited thereto as evidenced by the other embodiments illustrated.
  • the frame is suitably made of metal tubes or rods that are connected together by sockets or sleeves 24 as illustrated in FIG. 2 at la.
  • transverse struts I" of the frame are hingedly connected at 25 to the ground plate 17' as seen in FIGS. 3 and 4.
  • the tent cover 3 is below the frame In, although it can also rest on the frame.
  • the safety tent in the form ofa Faraday cage comprises, for example, a mctallized fabric, for which a cloth can be utilized, that has metal thread 21, 22 woven into the weft and also into the warp as in FIG. 1.
  • Metal litz wires 19 sewn on may also be as shown in FIG. 3.
  • the tent covering fabric can also be formed to be entirely electrically conductive by other means, for example, by production from a material which is conductive per se, applied with a brush, spraying on a metal coating, or covering with a layer of metal 20 as indicated in FIG. 2.
  • the tent 3 is fastened to frame I by releasable loops 5, which consist of an insulating material like rubber or plastic.
  • the material of this suspending means can be rigid or elastic.
  • a conductive floor covering such as, one provided with litz wire can be disposed.
  • a mctallized rubber mat I is preferably used.
  • this connection 6 can consist of metal litz 7 sewn on the tent and fastened of the frame 1 near the ground.
  • the mctallized tent cover which is conductively connected to the frame I and surrounds the occupants, prevents that any displacement currents due to the increase in potential of the frame 1 with respect to the environment can flow over the occupants, especially through any contact points between the occupants and the tent frame, and can seriously endanger the people. Additionally it should be pointed out that the conductive tent cover protects the occupants also against Vagabond currents which possibly occur if the tent is set up under trees having branches hanging down or in bushes.
  • FIGS. I and 2 each show a tent for accommodating one person.
  • This tent is suitably in the approximate shaped of a semisphere or an igloo where the seating cushion 9 for the occupant can be in one corner and the windows 4 to the left and the right of the opposite corner.
  • the seat 9 is suitably made of an insulating material, for example, a cushion of rubber or plastic that can be blown up.
  • the entrance flap I6 is provided with a zipper 8 which can be closed from the inside as well as from the outside. It is, of course, also possible to make larger tent units in this manner.
  • the invention is not limited to the illustrated form and configuration of the frame.
  • a ground plate l7 can be provided which is located in the interior of the tent and there constitutes a standing or locating surface for the feet of the tent occupant or occupants.
  • Size and arrangement of the tent, as well as of the chosen plate 17 and of the seat 9 may be chosen in such a manner in relation to the tent interior, that the occupant or occupants can assume a definite position in the tent and place the feet upon the ground plate (see FIG. 2 and the schematic drawing of FIG. 4).
  • the user is prevented from picking up a step voltage, while the Faraday cage affords a safeguard against direct lightening strokes. It is advisable not to make the ground plate too large, so that there is only room for the feet of the person or persons that can be accommodated in the interior of the tent.
  • the electrical connection of the ground plate with the earth can be optional, for example, by way of the base or ground struts l of the frame Ia, which may simultaneously serve for grounding the frame or the Faraday cage.
  • the ground plate 17 can be releasably connected with the struts I.
  • the plate 17 may be arcuated as indicated in FIG. 2 at 18 and resilient.
  • the differently shaped transverse struts I" of the frame lb are linked to the plates 17' and can be turned over downwardly or upwardly into a position perpendicular to the plate for transportation purposes.
  • the tent cover 3 is directly below the frame Ia and may be a Faraday cage. If the frame, as well as also the tent cover are designed as a Faraday cage, it is advisable to connect them conductively at several places. It would also be possible to provide the tent cover on the outside of the frame lb as indicated at 3" in FIG. 3. In that event the cover must have the properties of a Faraday cage.
  • the mesh width of the Faraday cage should be so narrow that no dangerous potential difference can arise between the person and the cage. Since the tent has merely a contact ground, it is under some conditions raised to several million volts when a lightening bolt strikes. A suitably narrow meshed cage safeguards against the person being "taken along" to this voltage, i.e., a sufficient coupling is provided between person and tent. In that event (see also the embodiment of FIG. I) there is no necessity for electrical reasons to provide a ground plate or the like in the tent that is conductively connected to ground so that the tent can also be closed entirely at the bottom and thus be satisfactorily sealed against the penetration of wind and dampness.
  • the tent is safely held on the ground by the weight of the occupant or occupants seated therein, i.e., it need not be separately anchored. This is essential because in the event of a suddenly arising storm the time is the frame, possibl the ground plate and the cover can be readily accommo ated and taken along in a portable con tainer such as a knapsack, a bag or the like.
  • FIGS. 5 and 6 illus trates the application of the invention, to a tent generally referred to as a house tent for camping purposes.
  • the supporting frame I3 is indicated in interrupted lines.
  • a living or sleeping unit 15 is tied by means of loops 14 which are only schematically illustrated (dash and dot lines), which unit is in the sense of the above explanations in the form of a Faraday cage made, for example, out of metallized fabric.
  • the inner tent part 15 may be made either as a separate living or sleeping unit and hung into camping tents that are already in existence. However, it is also possible to provide such a camping tent from the beginning with a tent portion in the form of a Faraday cage hung into its frame.
  • the dimensional proportions of the mesh screen should be such that it can conduct the lightening current which flows over the frame into ground. Only by way of example a mesh screen is mentioned made of copper litzen that is 5mm in cross section and of a mesh width of 3050cm.', the invention is not limited thereto. By means of the mesh screen dangerous step potentials are simultaneously avoided.
  • Shelter in the form of a tent providing protection for the occupant or occupants against lightning strokes, said shelter comprising a supporting frame, a conductive floor including metal capable of conducting lightning currents conductively connected to said frame, a shelter cover, insulating members such as loops of rubber or plastic material supporting said shelter cover on said frame at a distance to safeguard against jumping of lightning bolts, said frame and said floor forming a Faraday cage adapted to be conductively connected to ground.
  • said metal in said conductive floor is in the form of a ground plate or the like in the interior of said shelter which serves as a supporting surface for the feet of the occupant or occupants of said shelter.
  • Shelter in accordance with claim 4 comprising conductor means such as metallic struts conductively connecting said ground plate to said frame.
  • Shelter in accordance with claim 4 including an inflatable seat for each occupant arranged proximate said ground plate in a manner permitting the occupant of each seat to place his feet on said ground plate.
