Description

Tent

The present invention relates to a kind of tent, it discharges elastic force and sets up automatically by the spring members of tension in advance that belongs to this tent from.

This tent is known from patent disclosure publication WO 94,/11 600.In this patent, spring members is made of a single continuous steel spring, this spring forms two annulus when tent is put up, and one of them annulus struts the bottom of tent canvas as a under(-)chassis, and another annulus is promoted to tent canvas on the bottom.Can be folded, twist and tie together into a flat circle parcel when tent carrying or storage.But this parcel can be quite big because tent when putting up annulus must cover a people who lies low, so must on two dimensional directions, sizable stretching, extension be arranged at least.In addition, structure itself is just quite complicated and expensive.

Purpose of the present invention just provides a kind of this tent of mentioning in first section, but it has simple structure and low cost, is easy to travelling and carries and fold again, and account for still less space than tent known today under folded situation.

Putting up the shape that has vertical pipe under the situation according to the tent canvas that the present invention obtains.Spring members is made of at least one the continuous helical spring along this pipe.Each circle of spring struts tent canvas with maintenance as the annulus that delegation links to each other.This structure is fit to do single tent, and its lateral dimension is fit to a people who lies low.Yet the annulus of above-mentioned known structure must possess identical with personnel's that tent holds height at least lateral dimension or diameter, and annulus of the present invention or turn have much smaller diameter with respect to people's lateral dimension.Tent of the present invention is thus compared the same much smaller diameter that obtained with known tent under folded state.Mainly, this tent only comprises that two are easy to produce and cheap parts.This tent canvas can be made with single a slice rectangular cloth, and this cloth only needs vertical freely limit, edge to link together.Spring wire coiling that helical spring can plain mode shears off with one section and that made by the suitable material of tension in advance, this helical spring stretches automatically when the tubulose tent canvas is released.Therefore tent is barricaded as automatically, and availablely manually spring end is pushed toward each other and effortlessly folds up again.

Tent can only be with the tent canvas pipe of open end to constitute by one, and tent just has the characteristics that hide canopy like this, two ends is closed by each wall just can form a normal tent.At least one wall in these walls can advantageously be constructed to the part that extends axially of tent canvas, and this at least one wall can limit and seal with rope or by means of for example slide fastener.

Spring wire can have any cross section in principle.Preferably, cross section is circle, semicircle or rectangle.If the long side surface of the planar side of semi-circular cross-section or rectangular cross section turns to the inside facing to tent, for the people in lying in tent, this will be comfortable.

Spring must have multi-turn like this so that tent canvas is strutted and make length of spring compressed together, does not have spring will cause permanent deformation.On the other hand, in order to save production cost, and, do not need than required more circle in order tent to be folded to minimum as far as possible volume.When helical spring pitch spring diameter 1/8 and 1 between, particularly spring diameter 1/4 and 3/4 between the time, these conditions are able to best satisfy.

As mentioned above, tent can so just form one and have the dish type parcel that approximately equates with the helical spring diameter only with manually both ends of the spring portion being pushed toward each other and folds.Can advantageously not reduce in addition this diameter, method is that the circle that at first reverses in the dish type parcel with hand makes them form 8 word figures, joining of each circle is reversed two half parts of described 8 word figures in this 8 word figure again, thus make these two halves mutually near.Formed second dish type parcel thus, its diameter is approximately half of first parcel diameter.

Utilize described operation that spring wire is reversed around its center line, need a people, therefore permanent deformation can not occur manually to reverse each circle that is folded with the method.Therefore the cross section of spring wire must have a little polarity impedance unit, because spring also should be able to keep the tent canvas security extension, just sizable intensity must be arranged so be used as the material of spring wire, and for fear of permanent deformation, material also must be very flexible.

In fact, can reach these requirements when spring wire is made by a kind of like this material, the coefficient of elasticity of this material is less than 100,000kp/cm ², yield point is greater than 1.000kg/cm ²Suitable material is the plastics (fibre-amoured plast) of plastics, especially fibre-coated.

Yet the diameter of dish type parcel also can reduce, and its method is that each is torqued into the relative direction of respectively enclosing coiling with different directions around axle of spring with two ends of spring.With the method, utilizing the spring wire with flattened cross-sectional will be easily.When spring wire when being thin diametrically, spring can easily reverse around its axis, if spring has enough axial widths simultaneously, then spring can produce a pressure, and this pressure is big must being enough to setting up tent and keep tent canvas to open.

When tent was folded up with a kind of method in the said method, it can utilize at least one openable lock, is secured in the folding position as tape or similar device.

The present invention will be with the description of the following example (they only as an example) with reference in addition more fully explanation of accompanying drawing, wherein:

Fig. 1 is the phantom drawing of a tent of setting up of the present invention,

Fig. 2 shows the same tent be folded into first dish type parcel, and it has identical diameter with tent under having set up state,

Fig. 3 shows the parcel shown in Figure 2 that is reversed into 8 fonts along the direction of arrow,

Fig. 4 shows that how two of 8 fonts shown in Figure 3 reverse along the be hit by a bullet intersection point of spring coil of direction of arrow circle in figure 8 shape for half toward each other,

Fig. 5 shows two half parts that are reversed into 8 fonts that are close to mutually shown in Fig. 3 and 4, so formed second dish type parcel, it has half of diameter of first dish type parcel shown in Figure 2, and releasably fixing by tape.

Fig. 6 shows the spring of the tent of seeing from the end shown in Figure 1, and

Fig. 7 is shown as and reduces diameter and same spring that helical form is reversed.

Seen in fig. 1 is according to a tent of the present invention, whole by label 1 expression.Tent is on the position that rides over down when using on the bottom 2 (as the soil) among the figure, people 3 of recumbency in the tent.

Two major parts of tent are tent canvas 4 and a helical spring 5 that keeps tent to launch.Shown under the state put up, tent is the shape of vertical pipe 6, its two ends are respectively by first wall 7 and 8 sealings of second wall.

First wall 7 is made of circular tent canvas sheet, and second wall 8 is made of the prolongation of that piece tent canvas that forms tent canvas pipe 6.Form a circle cover 10 that has rope 11 at 9 places, edge of this extension.Unclamp rope, the user can make the opening of a turnover tent, and tightens up a rope, and the user just can be closed to tent the degree of wanting.Second wall 8 is only partly closed among the figure, because will leave a ventilation opening 12.Can think that first end wall 7 can the method the same with second wall 8 be adjusted if think so also.

Helical spring coiling under tension in advance makes tent canvas pipe 6 keep frapping.With hand the tent two ends have just been formed first dish type parcel 13 among Fig. 2 along direction of arrow extruding, it has the diameter identical with helical spring 5.

This first parcel 13 usefulness hands reverse along the direction of arrow and form 8 word figures among Fig. 3.

Two half parts of 8 word figures are respectively 14 and 15 among Fig. 4, and intersection point that they form between the turn 16 reverses toward each other along the direction of arrow again.

Among Fig. 5, two

half parts

14,15 are kept being close to mutually, tent has reached its final folding position thus, the i.e. shape of second dish type parcel 17, its diameter only wraps up half of 13 diameter dimensions for first, in other words, as be in half of tent 1 diameter dimension under the state of putting up.Therefore tent accounts for little room under folded state, so be easy to carrying and storage.

In the illustrated case, tent can be fixed in folded state by tape 18 with opening, and this tape has a hole 19, this hole be positioned at half fulcrum 20 on 15 of 8 word figures and cooperate.When tape unclamped, tent can be bound to position shown in Figure 1 automatically.Therefore tent is set up automatically.

In the illustrated case, spring is to utilize the brace 21 on the tent canvas inboard to be fixed on the tent canvas.Also available one continuous cover replaces.Perhaps, spring can be bonded on the tent canvas.The method is especially convenient when with flat spring wire.

Spring can be fixed on (not shown) on the closed circle at two ends, and this annulus is represented the axial limit of tent canvas pipe.Yet in Fig. 1, each end of tent canvas pipe is the annulus of an opening, is respectively 22 and 23, and they form the spring spiral coil very simply and continue the plane circle that.

Among Fig. 6 be under this state from the spring shown in the end, this moment tent put up, promptly spring and tent have same diameter.For the purpose of clear, tent canvas does not show in the case.Among Fig. 7, two ends of spring are reversed with relative direction around axle of spring along direction shown in the arrow.Therefore diameter has reduced, and the tent on final folding position will be gained all the little space of possibility like this.

This final folding position can be so fixing, that is: second end wall 8 is turned over and on the disc-shaped part that has reduced diameter, with rope 11 opening of end wall is fastened then.

When tent folds with the method, can use a kind of flat spring wire expediently with less relatively radial dimension and larger axis to size.So just be easy to spring is reversed, thereby also tent together reversed to little diameter, offer spring simultaneously and set up tent and make the required power of the normal expansion of tent canvas.

According to the present invention, single tent is being put up the diameter that has 120cm for example under the situation and the about length of 200cm.Tent generally has 60cm or littler diameter and the about thickness of 2-3cm under folded state.

Reach the present invention described above shown in the accompanying drawing and be based on the hypothesis of cross section for circle.Yet should understand it only is an example, and tent can have the cross section of any appropriate within the scope of the invention.

Like this, cross section can mainly be quadrangle, trapezoidal or triangle.

As an embodiment especially easily, cross section can have a planar side, and this side has sizable flexibility and terminates on the cycloid.In the use location, planar side will be positioned on the bottom, and cycloid arches upward above bottom.Planar side will form a bed easily for the people who lies in the tent like this, and the shape that cycloid has can make the suitable load that produces from for example tent canvas deadweight on the tent of bearing of spring.
