Definitions
- the invention concerns a tent of the kind which automatically is put up by releasing the elastic force from a pre-tightened spring unit which is belonging to the tent.
- Such a tent is known from the patent publication WO 94/11600.
- the spring unit consists of one single continuous steel spring which forms two straps when the tent is pitched.
- One of the ⁇ e straps works as a sort of a bottom frame, which keeps the foot of the tent canvas distended while the other one lifts the tent canvas above the underlying layer.
- the tent When the tent is to be transported or stored, it can be folded up, twisted and bound together to a flat, circular package. This package will, however, be rather large, since the straps, when the tent is pitched, will have to span a lying person and therefore necessarily must have a rather large extension in at least two dimensions. To this can be added that the construction in itself is rather complicated and expensive.
- the object of this invention is to provide a tent of the type mentioned in the opening paragraph with a simple construction and a low production price, being easy to travel with and fold up again, and which in folded up condition takes up less space than known until now.
- the tent canvas having the shape of a longitudinal tube in pitched condition, and that the spring unit consists of at lea ⁇ t one continuous screw spring running along this tube.
- the windings of the spring will work as a row of coherent straps holding the tent canvas distended.
- the construction is suitable for a one-man tent with a tranverse measurement suitable for one lying person.
- the straps of the above-mentioned known construction neces ⁇ arily had to have tranverse measurements or diametres, which at least were as large as the height of the person, whom the tent should accomodate
- the straps or the spring windings according to the invention can have a much smaller diametre in relation to the tranverse measurement of the person, whereby the tent according to the invention equally obtains a much smaller diametre in folded up condition than the tent known.
- the tent consists of only two components which both are simple and cheap to produce.
- the tent canvas can thus be produced from one single piece of rectangular cloth, which only have to be joined together along the free longitudinal edges.
- the screw spring can in a simple way be wounded up by a length of spring thread cutted off and being of suitable material with a pre-tightening, which automatically extends the tubular tent canvas when being released.
- the tent i ⁇ therefore self-pitching and can with effortles ⁇ ea ⁇ e be folded up again by manually squeezing the spring end ⁇ again ⁇ t each other.
- the tent can con ⁇ i ⁇ t only of a tent canva ⁇ tube with open end ⁇ , whereby the tent have the character of a shelter.
- a proper tent can be created by closing the ends with walls. At least one of these walls can advantageously be constructed as an axial prolongation of the tent canvas which forms the tent canvas tube, and be closed by constriction with a string or by mean ⁇ of e.g. a zipper.
- the ⁇ pring thread can in principle have any cross section, whatsoever.
- the cro ⁇ sections preferred are round, semicircular or rectangular. It will be pleasant for the person, who lie ⁇ in the tent, if the plane ⁇ ide of the ⁇ emicircular cro ⁇ section or the long side of the rectangular cros ⁇ section turn against the inner of the tent.
- the ⁇ pring mu ⁇ t have ⁇ o many winding ⁇ that the tent canva ⁇ can be di ⁇ tended and the ⁇ pring be squeezed together, without it thereby will cause permanent deformations.
- the screw spring has a pitch of between 1/8 and 1, and especailly between 1/4 and 3/4 times the diametre of the ⁇ pring.
- the tent can, as said before, be folded up merely by squeezing the spring ends manually against each other, so that a disc- ⁇ haped package is formed approximately with the same diametre as the screw spring.
- This diametre can, however, advantageously be reduced additionally by fir ⁇ t manually twisting the windings in the disc-shaped package ⁇ o that they form a figure of eight, and then twist the two halves of said figure of eight around the intersection point of the winding ⁇ in the figure of eight, so that the two halves will be abutted on each other.
- a second disc-shaped package is formed with approximately half the diametre of the the first package.
- the cros ⁇ ⁇ ection of the ⁇ pring thread mu ⁇ t therefore have a ⁇ mall polar re ⁇ i ⁇ tance element, and ⁇ ince the spring furthermore shall be able to keep the tent canva ⁇ safely distended, the material, which i ⁇ u ⁇ ed for the spring thread, mu ⁇ t have a rather large strength. In order to avoid permanent deformation ⁇ the material must furthermore be very elastic.
- the diametre of the di ⁇ c- ⁇ haped package can, however, al ⁇ o be reduced by twi ⁇ ting the ends of the ⁇ pring in different directions around the spring axis to the opposite direction of the one in which the windings are turning.
- a spring thread with a flat cross section.
- the spring will then easily could be twisted arount its axis, and if at the same time the spring is dimensioned with adequate axial width, the spring can be brought to produce a pressure, which nevertheles ⁇ is large enough to pitch the tent and keep the tent canvas distended.
- the tent When the tent is folded up in one of the said ways, it can be fixed in folded position by means of at least one releasable lock, e.g. a belt or similar means.
- at least one releasable lock e.g. a belt or similar means.
- Fig. l shows, seen in perspective, a pitched tent according to the invention
- Fig. 2 show ⁇ the ⁇ ame tent folded up to a fir ⁇ t di ⁇ c- ⁇ haped package with the ⁇ ame diametre a ⁇ the tent in pitched condition
- Fig. 3 how ⁇ the package shown in fig. 2 when it is twisted to the figure of eight in the direction of the arrows,
- Fig. 4 shows how the two halves of the figure of eight, shown in fig. 3, are twi ⁇ ted again ⁇ t each other in the direction of the arrow ⁇ around the inter ⁇ ection point of the ⁇ pring winding ⁇ in the figure of eight.
- Fig. 5 ⁇ how ⁇ the two halve ⁇ of the figure of eight, ⁇ hown in fig. 3 and 4, twi ⁇ ted to be abutted on each other, ⁇ o that a ⁇ econd di ⁇ c- ⁇ haped package i ⁇ formed which ha ⁇ half the diametre of the first disc-shaped package shown in fig. 2 and releasably is fixed by means of a belt,
- Fig. 6 show ⁇ the spring of the tent shown in fig. 1, seen from the end, and
- Fig 7. shows the same spring helically twisted in order to reduce the diametre.
- a tent according to the invention designated as a whole with the reference number l.
- the tent is in position for use pitched on an underlying layer 2, e.g. soil, with a person 3 lying in the tent.
- the two main parts of the tent are the tent canva ⁇ 4 and a screw ⁇ pring 5 to keep the tent di ⁇ tended. in the ⁇ hown pitched condition the tent ha ⁇ the shape of a longitudinal tube 6, which at the ends is closed by a first wall 7 and a second wall 8, respectively.
- the fir ⁇ t wall 7 con ⁇ ists of circular piece of tent canva ⁇ , while the ⁇ econd wall ⁇ con ⁇ ists of an extension of that tent canvas which forms the tent canvas tube 6.
- a round-going casing 10 With a string 11.
- the u ⁇ er can make an opening for the passage in and out of the tent, and by tightening the string, the user can close the tent to the wanted extend.
- the second wall 8 is only partly closed, ⁇ ince a ventilation opening 12 is left. It goes without saying that the first end wall 7, if ⁇ o wanted, can be adapted in the ⁇ ame way a ⁇ the ⁇ econd end wall 8.
- the two halves 14, 15 are brougth to rest against each other, whereby the tent has reached its final folding position in the ⁇ hape of a ⁇ econd di ⁇ c- ⁇ haped package 17 with a diametre only half the ⁇ ize of that of the first package 13 or, said in other words, as the tent 1 in pitched position.
- the tent will therefore take up very little space in folded up condition and is consequently easy to transport and store.
- the tent is fixed in folded up condition releasably by means of a belt 18, which ha ⁇ a hole 19 which fit ⁇ to a pivot 20 on the half 15 from the figure of eight.
- the tent will automatically jump up to the po ⁇ ition shown in fig. 1.
- the tent is therefore self-pitching.
- the spring is fixed in relation to the tent canvas by means of straps 21 on the inner side of the tent canva ⁇ .
- a continuou ⁇ casing can be used.
- the ⁇ pring can be glued to the tent canva ⁇ .
- the spring can be fixed to a closed ring (not shown) which mark ⁇ the axial limitation ⁇ of the tent canva ⁇ tube.
- a closed ring (not shown) which mark ⁇ the axial limitation ⁇ of the tent canva ⁇ tube.
- This final folding up po ⁇ ition can be fixed by turning the second end wall 8 backwards and around the di ⁇ c- ⁇ haped package with reduced diametre and then lace up the opening of the end wall with the ⁇ tring 11.
- a one-man tent according to the invention can, in pitched condition, have a diamtre of e.g. 120 cm and a length of approximately 200 cm. In folded up condition the tent will typically have a diametre of 60 cm or le ⁇ and a thickne ⁇ of approximately 2-3 cm.
- the cross section can be mainly quadrangular, trapezoidal or triangular.
- the cros ⁇ section can have a plane side, which with rather large bendings end ⁇ up in a cycloid.
- the plane side will then repose on the underlying layer, while the cycloid arches above the underlying layer.
- the plane side will form a convenient couch for the person who lies in the tent, and the cycloid ha ⁇ a shape, which makes the spring suitable to take up loadings on the tent from e.g. the self-weight of the tent canvas.
