Definitions
- the present invention relates to the field of articles which comprise a structure in one or more arches, and which are foldable between a deployed use position and a folded storage position, in which folded position they have a substantially circular configuration.
- This invention finds particular application folding items of the tent type, shelter, or ball game device.
- These items typically include an upper canvas, often referred to as a roof covering in the case of a tent or shelter. This is called arch structure when the fabric is secured to flexible structural elements which take, in the deployed position of the article, a circular arc configuration.
- These structural elements may consist of flexible rods with elastic return, in particular formed of rods of composite material or metal or plastic, the rods being optionally connected to each other.
- the flexible rods are in the rectilinear state in the folded position of storage of the article and do not take the configuration in an arc in the assembly of the article. This is particularly the case of some tents commonly referred to as dome tents.
- the structural elements form a closed loop, this loop in particular to give the article its three-dimensional dimension.
- Such an article is described for example in US-3,960,161.
- the structure element, in the form of closed loop is in the folded position of the article, in the form of three superimposed circular turns. It is the same for the tent described in US-3,675,667.
- the folding of the article consists mainly, from the form set volume, so three-dimensional, to nest the loops forming the article to fold back into each other.
- the loops are imbricated simultaneously with their formation.
- a substantially planar figure is first formed with the loop of the arch structure with three smaller, substantially aligned loops (that is, the three respective centers of which are substantially aligned), and then superimposed the three loops smaller by antagonistic pressures at both ends of the previously formed three-loop plane figure, thereby pivoting the two ends of this plane figure in the direction of one another.
- the described method therefore consists of a succession of laborious steps during which, and at the end of which, the object to be folded is kept in a three-dimensional configuration, with the exception, of course, of the final configuration in three superposed turns that can be likened to a substantially flat configuration, and possibly of an intermediate configuration forming a substantially flat figure with three loops.
- the problem that arises then is to have a method of folding an article which comprises a hoop structure, from a deployed position to a folded position in which the hoop structure forms a series of three superimposed turns, which is easy and quick to implement, especially by a single person.
- the object of the invention is therefore to provide a solution to the aforementioned problem among other problems.
- the invention thus relates, according to a first aspect, to a method of folding an article which comprises a folding arch structure on itself comprising at least one closed loop, in a folded position in which this loop is presented.
- the shape of three superimposed turns are preferably substantially circular, but may also be oblong or oval.
- the method consists in particular of forming with the loop a first substantially flat figure with three loops: a central loop and two lateral loops, all substantially in the same plane.
- each of these lateral loops is then successively brought back to said central loop to form the three superimposed turns.
- a first of the two side loops is first brought back on the central loop, then the second of these two side loops is brought back on the central loop and the first side loop, to form these three superimposed turns.
- a second substantially flat figure is formed from the first substantially flat figure, by bringing a first of the two lateral loops onto the central loop, and then forming the three superposed turns by bringing the second of the two lateral loops onto the second substantially flat figure.
- the folding method is easy to implement, in particular by a single person, because of the passage through a step at the end of which the initial loop forms a flat figure with three smaller loops.
- Maintaining the loop in a substantially flat shape at the end of each step (step of creating the first substantially planar figure with three loops in the same plane, step of creating the second substantially flat figure by superposition of a first lateral loop on the central loop, and superposition step of the second lateral loop on the assembly formed by the superposition of the first lateral loop on the central loop, that is to say on the second substantially flat), facilitates the implementation of folding, for example by keeping the assembly on the ground.
- a first portion of the loop having a vertex is grasped and brought back to the plane of the complementary portion of this loop also having a vertex, so that the first portion crosses the complementary portion at two crossing points, and secondly that the top of the first portion is found beyond the top of the complementary portion.
- the initial loop is subdivided into three smaller loops in the same plane and ready to be superimposed to form the three final turns.
- first plane figure we seize a first portion of the loop, which is twisted so as to create a first cross point. Then we seize a second portion of the loop, opposite to the first portion, which is also twisted so as to create a second crossing point.
- this first or second lateral loop is rotated around its point of intersection with said central loop.
- the arch structure comprises several loops of substantially the same size.
- these loops are superimposed so as to form virtually a single closed loop, to which the method as presented above can then be applied.
- the superimposed loops are held together by means of at least one attachment element, for example a diametral strap or a link, to facilitate the subsequent manipulation of this loop superposition as a single loop.
- at least one attachment element for example a diametral strap or a link
- the three superposed turns are held together by means of a fastening element preferably of diametrical strap type, or of link type.
- the three superposed turns are inserted in a cover preferably substantially circular, but which can also be oblong or oval.
- the invention also relates, according to a second aspect, to an article comprising an arch structure itself comprising at least one closed loop, folded into a folding position in which the loop is in the form of three superimposed turns, preferably substantially circular, obtained by the folding method as presented above.
- FIG. 1 shows diagrammatically and in perspective the arch structure of a tent-type article in the deployed position
- FIG. 2 schematically represents a tent-type article in the deployed position
- FIGS. 3 to 6 show schematically the various steps of the method of the invention, in a first embodiment variant
- FIGS. 7a to 7c show schematically the transition from the stage of FIG. 3 to the stage of FIG. 4 (formation of the first plane figure in the first embodiment),
- FIG. 8 to 12 show schematically the different steps of the method of the invention in a second implementation variant.
- Figure 1 an arch structure of a tent type article 1 in the deployed position.
- the structure comprises two closed loops 2, 2 '. Specifically, the structure has an upper loop 2 and a lower loop 2 '.
- FIG. 1 For the purpose of explaining the folding process, which is discussed later in this description, reference is also made in FIG. 1 to different points of the upper 2 and lower 2 'loops.
- FIG. 1 also refers to the two ends or tops 10 and 11 of the upper loop 2, at the highest points of this upper loop 2 in the deployed position, ie at the points of this upper loop 2 furthest from the lower loop 2 'in the deployed position.
- this figure 1 shows two other opposite ends or vertices 12 and 13 of the lower loop 2 ', at the points of this lower loop 2' furthest from the upper loop 2 in the deployed position.
- 2 schematically shows the tent 1 provided with the arch structure shown in Figure 1, with a fabric 7, generally called roof fabric, stretched between the arches of the structure.
- FIGS. 3 to 6 show the different main steps of the folding method of the invention, in a first implementation variant, applied to a general folding article which comprises at least one closed loop 2.
- FIG. 3 thus represents the closed loop 2, such as that represented in FIG. 1, seen from below.
- this loop 2 is not necessarily flat, as will be seen in particular with reference to Figures 7a and 7b.
- the representation mode chosen in bottom view shows the projection of this loop 2 in a plane, so in the form of a plane curve which can be oblong or circular, for example.
- the first portion 3 of the loop 2 comprising the vertex 3a is grasped, and it is gradually brought back into the plane of the complementary portion 4 of the loop 2 which includes the vertex 4a.
- pressure is exerted along an axis perpendicular to the axis connecting the vertices 3a and 4a to tighten the first portion 3 for the subsequent formation of the central loop 2b.
- the first portion 3 intersects the complementary portion 4 at two crossing points 5 and 6, and the vertex 3a of the first portion 3 is found beyond the vertex 4a of the complementary portion 4.
- FIGS. 7a to 7c The operation to move from the stage of FIG. 3 to that of FIG. 4 as described in the preceding paragraph, is decomposed in FIGS. 7a to 7c, in a succession of perspective views of the loop 2.
- FIG. 7b corresponds to a view in FIG. perspective of the loop 2 in an intermediate position, when the first portion 3 of the loop 2 has not yet been completely brought into the plane of the complementary portion 4.
- one of the lateral loops 2a is brought back onto the central loop 2b, to form the substantially flat intermediate figure, or second substantially flat figure, as represented in FIG. 5.
- the lateral loop 2a is rotated around its point of intersection with the central loop 2b.
- this side loop 2b is rotated around its crossing point 6 with the central loop 2b.
- the loop 2 is in the form of three superimposed turns 2a, 2b and 2c, as shown in FIG.
- turns are preferably substantially circular, but may also be oblong or oval.
- an attachment element to maintain these three turns 2a to 2c together. It may be for example a diametral strap, preferably elastic, or one or more links.
- the superposition of the two loops 2 and 2 ' is obtained by making coincide the vertices or ends 12 and 13 of the lower loop 2' furthest from the upper loop 2 in the deployed position, respectively with the ends or vertices 10 and 11 of the upper loop 2 farthest from the lower loop 2 'in the deployed position.
- the lower loops 2 'and upper 2 thus joined or superimposed, then virtually form a single loop 2 as shown in Figure 3 or 7a.
- this virtual loop 2 in fact comprising the two lower loops 2 'and upper 2 together or superimposed, it can be provided to maintain these two loops 2, 2' together by means of at least one attachment element ( one or more links for example).
- the formation of the first three-loop flat figure 2a, 2b, 2c can be obtained in another manner, as shown in FIGS. 8 to 12.
- a first portion 8 of the loop 2 as shown in FIG. 8 is grasped, which is twisted so as to create a first crossing point 5, as shown in FIG. 9.
- the first three-loop plane figure, one central 2b, and the other two lateral 2a and 2c thus comprises three loops 2a to 2c substantially aligned (in the sense that their respective centers are substantially aligned), while in the first variant (FIG. 4), the two lateral loops 2a and 2c are offset with respect to the central loop 2b so as to form a kind of clover (in the sense that their respective centers form the vertices of a substantially isosceles triangle, possibly equilateral ).
- this side loop 2b is pivoted around its point of intersection 6 with the central loop 2b.
- the loop 2 is in the form of three superposed turns 2a, 2b and 2c of substantially circular preferences, or possibly oblong or oval.
- a cover preferably substantially circular, provided for this purpose.
- an attachment element to maintain these three turns 2a to 2c together, such as a diametral strap, preferably elastic, or one or more links.
- the present description is given by way of example and is therefore not limiting of the invention.
- the invention is not limited to the folding of a tent as shown in Figures 1 and 2, but applies to a tent whose arch structure has a single loop 2 or more than two loops 2, 2 .
- the method of the invention is not limited to the folding of a tent, but concerns the folding of any article with an arch structure comprising at least one closed loop, so that this loop presents itself in the folded position, in the form of a superposition of three turns. Therefore, the method also applies to other examples of such items, such as shelters or collapsible ball game devices.
- the invention is not limited to the two modes of implementation presented above for the formation of the first three-loop plane figure. Other ways of forming such a figure can be envisaged, provided that one goes through this step of forming a first three-loop plane figure, that is to say three loops substantially in the same plane, that it can then easily be brought back to one another as described above.
