    Description

    Technical Field



    [0001] The present invention concerns the technical field of folding and portable supporting apparatuses, such as stands, seats, tables, hammocks, folding beds, camping beds and all the structures that are mainly but not exclusively suitable for camping, hiking, outdoor activities, trips and as equipment for emergency camps. All the situations where lightness, easy opening and folding, as well as the minimum amount of space in closing phase, are decisive for their use. In particular the invention concerns an innovative group of supporting apparatuses that are extremely lighter, more comfortable and more solid than commercial ones.

    Background Art



    [0002] The structures of most of the commercial supporting apparatuses, which can be folded in compact bundle, are articulated with poles, hinge and supporting textile apparatuses at times cooperating, such as the popular crossed style chairs, whose infinite variations are available Fig. 1. Their weight is on average from 2.5 to 4 kilograms and derives from thousand-year old structural models.

    [0003] A version of three-legged camping stool Fig. 2 is composed of three poles joined on the upper part on the extremes to a piece of fabric, a hinge on three axes, in the middle of the poles ending on the ground without other constraints. Essentially this structural diagram copies the same structure of the seat of Fig. 1 wherein most of the elements of the frame are heavily strained by bending (1), shearing and torsional stresses. The consequence is a high materials expense compared to the unit of sustained weight. So these models are very heavy or very fragile or result quite low.

    [0004] Furthermore the big dimensions of the materials involve high weight and significant volumetric encumbrances, therefore these objects neither are "pocket size" nor are "portable" meant as the possibility of storing them in a small rucksack or in a small bag. Many of these apparatuses are at most "transportable" that means they can be folded and stored in a car boot or they English Description can be carried over one's shoulder for a short way. An example of the limits of these apparatuses is given by a tiny stool Fig. 3 that is only 8 or 9-inch (20,32 or 22,86 cm) high and has a coplanar closure of joined elements of traction (2) which are adjustable by a hook with the possibility of pre-tightening. Most of the elements of the structure are composed of full iron and compression exposes them to different strains. This microchair weighs a little less than one kilogram anyway, and has a limited functionality.

    [0005] An American patent made by A.F. Draper in 1938 US2139673 A Fig. 4 probably didn't commercially succeed, but significantly improves the structural economy of foldable objects: a metal structure, in any case heavy because of the technological limits of the time. A polyhedral shell of means of traction composed of different materials contains the structure. Eight poles converging to a central junction hinge in pair and to every pole going up, corresponds another one going down.

    [0006] Draper's seat structure not only has a doubtful effectiveness and complicated mechanics, but also has a significant problem: the shell of the means of traction strains all parts of the apparatus in the right way, but the four side tensioners are put under stress, in case of torsion between the supporting surface (3) and the one on the ground (4), only when the supporting surface has begun to rotate and the upper and lower extremes of the side means of traction move away one another. This effect makes the seat unstable and damages the hinges, because the stresses they are subjected to are not orthogonal to the angles of their pins, so the torsion damages the poles.

    [0007] Regarding commercial foldable camping beds, the ratio of volume to maximum loading is even more significant: the average weight of these apparatuses, in order to hold a person who weighs 80 kilograms, is about 5 kilograms. In case of folding or detachable hammock stands, it raises at least to 12 kilograms. These weights discourage people carrying these apparatuses without using a means of transport. It is still a question of structures composed of elements that are exposed to great leverages and high torsional stress. Other portable and foldable supporting apparatuses are also known from US4290643 A and GB191106468 A.

    Advantageous Effects of Invention



    [0008] The aim of this invention is to provide a new structural base and some innovative solutions which enable to significantly reduce the weight and the encumbrance of some currently in use folding supporting apparatuses such as: supports, stands, seats, tables, camping beds and hammock stands for outdoor use and camping. According to the invention it is provided a portable and foldable supporting apparatus as claimed in claim 1, which describes a series of structural elements that are symbiotic with other specific technical solutions and enable to realize apparatuses on average five times lighter and about five times less bulky than the currently used ones. By copying a structure that is common in many vertebrates and other natural organisms, the invention is realized by making an inner skeleton mainly composed of compressed elements and an external shell of tensors, mainly stressed while in traction and adding to this so to say "natural" apparatus a series of applications and technical solutions that enable to realize apparatuses useful for the desired function. Moreover, the aim of the present invention is to realize the said apparatuses with the best solutions regarding ergonomics, easiness of use, stability, and to realize them with the available technology and materials, and with the best ratio between weight capacity and the weight/encumbrances of the object.

    [0009] For two-legged seats Fig. 5, three-legged seats Fig. 6 or more legs; for tables Fig. 40 and Fig. 41 them as well equipped with a varying number of legs as the supports of different functions such as high chairs Fig. 38 or pelvic supports Fig. 39 it is used a structure composed of an inner skeleton made of tubes or poles that converge on a central horizontal junction. This junction hinges an end of the said poles and its polygonal sides are the pins of the said hinges; from this junction, when the structure is unfolded and in use, the poles are set one upwards and one downwards, in cyclic way, in a varying number of pairs as in Fig. 9, arranged as an anti-prism. In these apparatuses, according to the invention, the structures is completed by a "shell" that is a closed system of means of traction which are composed of materials flexible to transverse stressessuch as cables, ropes, bands, fabrics and laminas. The said means of traction join all the poles vertexes opposite to the central junction so as to each vertex joins at least other three vertexes of the other poles creating this apparatus of "shell" made of tie-straps that provides a stable constraint for all constituent parts.
    The whole system works as a closed tensile structure. In the upper part, the means of traction are composed of textile surfaces or at least flexible ones that serves as support for people or objects and are integral part for the means of traction. As all the components of this structure are spared from almost every stresses caused by bending, torsioning, shearing, the result are extremely rigid and solid apparatuses using the least amount of raw materials.

    [0010] In unfolding/folding phase of the apparatus, it is possible to stop or lengthen the bonds of a certain number of means of traction in order to relax the whole structure and then fold all elements, including the supporting surfaces of the structure, in parallel, ordered, compact bundle Fig. 13 and Fig. 16. As in the technique of sails or medical corsets, it is possible to join to the supporting surfaces of the seats some flexible surfaces (14) reinforced with thin and semi rigid sticks (15) to obtain folding backrests; these surfaces are spread by the sticks when in use, but they are supported by the user's back and are flexibly joined to the side edge of the supporting surfaces. In a similar way, for some seats are provided expansions (16) of the supporting surfaces over the polygonal limit given by the vertex of poles. The said expansions are supported in a similar way on the backrests by sticks (15) that are coplanar integrated in the same supporting surface. According to claim 1, it is an optimal solution the partial rotation of the polygonal supporting surface of the seats with respect to the polygon of the base Fig. 4; this shape of the frame and of the means of traction dictates a tetrahedral shape to the two-legged seats/supporting surface Fig.5 and a similar anti-prismatic shape to the seats with a higher number of poles. The said anti-prismatic shape is extremely rigid and minimizes movements and distortions of the apparatus when under load. In case of not dynamic load, as for the case of the tables Fig. 40 and Fig. 41 it is possible to use alternatively a prismatic structure with only one side tensioner (17) per pole: Fig. 17; or crossing means of traction (18), as in diagram of Fig. 18 wherein the poles are joined on vertical planes in pairs as in the geometry of prism, that is with the 3 edges of the upper supporting surface polygon parallel to the base polygon, in this case the hinges of the poles with the junction are joined one on the other in order to simplify the closure. For camping beds apparatuses Fig. 46 and for hammocks stands ones Fig. 42, structural principles are the same, but there are two junctions (64). They are vertically oriented and are spaced out by a horizontalpole; the hinges are similar to a bone joint as in the femoral head, in order tohave more movement directions and to give more elasticity to the structure.

    [0011] These apparatuses are closed in the same way of the ones of the seats, by loosening the hooks and by loosening one or more of the means of traction under the structure, but in order to have more stability the directrixes of these tie straps also involve the point of contact among the junctions and the central pole that joins them. Concerning these two apparatuses, only a part of the anti-prismatic configuration of the means of traction takes form, but the torsion on the longitudinal axis of the apparatus is blocked by ground contact of the feet. The poles of these quite big folding apparatuses can be sectioned or halved, with proper links connected, in order to reduce these structures and make them more portable when closed. All the apparatuses subject-matter of the present invention have spread and hardly tightened supporting surfaces that result more comfortable than the currently used ones which are often only constrained and tend to bundle up the users' body. Further advantages are deducible by the subordinate claims.

    Examples



    [0013] As set forth in the next part of the present description, the primary concept of the invention can be extended to object meant for different functions, but which are all foldable supporting structures for people or objects. In the specific instance the concept of the present invention not only enable to make chairs, but also to make stands, tables, folding beds and others similar items. The said particular examples are not exclusive, those solutions referring to the attached drawings concerning the case of a chair, are not to be meant with a restrictive sense but they can be widen to other apparatuses. In general, the invention concerns the innovative use for these supporting apparatuses of an unusual structural principle and of some further technical applications, which enable to easily use and fold these apparatuses. In the sample four-legged chair presented in fig. 7, when in use, a central junction (5) hinges the ends of the four poles pointing downwards (7) and of those pointing upwards (6). The ends of the poles (22), oriented upwards and opposite to the junction, are joined to the vertexes of a polygonal surface made of textile or the like material, (13) which represents the seat of the chair. The said vertexes are joined through proper links (23) to some side means of traction (24) that can be composed of extended surfaces as in Fig. 19 or of linear elements as: ropes, cables, bands or laminas.

    [0014] These means of traction are here set in the optimal conformation, two directions that starting from the vertexes of the supporting surface, branch off joining two different links (25) placed on the ends of the four poles oriented downwards. All the legs of the chair are still further joined one another parallel to the ground by other means of traction (26), which are placed in the lower part of the structure and complete the closure of the "shell" of means of traction that includes the structure of the poles. The elimination of the most bending, shearing and torsional stresses from this structure enables to economize on the dimensioning of materials and it is the distinguishing feature of this invention.

    [0015] The whole structure is relaxed by releasing or lengthening of this means of traction placed in the lower part (27), and it can be easily folded in this way: Figs. 11, 12, 13; all the poles remain joined to the central junction, in a bundle of parallel poles, which is possible to aligning the means of traction and, among them, the supporting surface. Parallely folding the elements of the apparatus it is possible to reach the maximum closure compactness and the maximum length of the closed structure corresponds to the exiguous and uniform length of the poles. Fig. 20 represents a particular closing/releasing process of the lower means of traction. For example, in a three-legged chair a group 4 of three bands or straps (28) joins the feet (29) to a polygonal ring (30), that is placed in a central position, which then goes back to the buckle (31); the said buckle can be pushed away from its central position in order to tighten the apparatus and, in the opposite direction, it can be slid toward the centre so as to relax the structure during the closing phase. In this not exclusive solution, the terminals of the poles on the ground Fig. 21 are preset to join them and are composed of three elements: - A small cup (32) that surrounds the poles or tube and expands so as to support the band of the lower means of traction (33) which then joins a pair of side means of traction (34). - A spherical cap (35) and a screw (36) that intersects all the elements which complete and compact the structure placed on the ground. The bands, which complete the lower part of the structure, are perforated where the screw pass through it, and these holes are reinforced by an eyelet (37); other eyeletted holes are placed some centimetres apart along this band and enable to choose some adjustment for height and inclination of the structure as schematized in Figs. 22, 23 and 24. A particular arrangement of the poles around the junction is decisive for the stability of these apparatuses, that is the poles around the junction are linked or hinged in such a way as to each pole pointing upwards hinges between two pointing downwards, and the ones pointing downwards hinge between two pointing upwards. It serves to give the structure astable anti-prismatic shape, as schematized in Fig. 9 wherein the polygon represented by the supporting surface of the seat is rotated of half side with respect to the polygonal base, which is delimited by the feet of the poles. In Figs. 26, 27, 28, 29 and 30 seats are represented from above respectively provided with 2, 3, 4, 5, 6 pair of poles arranged in this way. The outer means of traction can be fully replaced, or the most of them, by a shell of flat surfaces joined one another and internally tightened by the previously described structure of poles and junctions, as represented in Fig. 19 wherein the frame with pentagonal antiprismatic base extends and is braced by a textile covering. The backrest and the armrests as well are placed onto it supported by sticks (38). A particular shape of the central junction Fig. 31 and Fig. 32 has a junction divided into two parts, the first part (39) is placed onto the other and contains the hinges of the poles pointing downwards; the latter (40), placed under the first one, hinges the poles pointing upwards. Therefore, the poles of a series intersect with the ones of the other series, alternating. The two semi-junctions can be screwed by a screw joint (81) when are drawn up. In this phase the structure expands and tightens the shell of the means of traction. When the two junctions are released, they can be distanced until the poles of the two groups are gathered in a parallel bundle, as shown in the diagram of Figs. 14, 15 and 16 wherein the two semi-junctions are set at the ends of the said bundle. This alternative structure as well has an antiprismatic shape and opening or lengthening of the means of traction are not required as the structure of poles gathers up and reduces or expands outwards.

    [0016] Other structures like the anti-prismatic one, but less rigid, can be chosen too.
    The diagrams of the means of traction which can be applied to the frame of these different apparatuses are schematized in Fig. 17 and in Fig. 18; furthermore mixed bracing systems for this models exist: In the seat support Fig. 33 with at least three poles pointing upwards (41) and only one pointing downwards (42) a structure which does not belong to the said models has been chosen, but also in this case there are not elements in the frame which are flexed or subjected to torsion. In this apparatus it is also possible to add an adjustable lengthening module (43), between the feet and the pole pointing downwards. This apparatus as well has a tetrahedron shape, as the one of Fig. 5. Also the support/seat shown in Fig. 5 has the minimum number of poles: two pointing downwards (45) alternating the two pointing upwards (46), and has the same shape and triangulation of the side means of traction of the other anti-prismatic seats. Furthermore, the supporting surface (13) is tightened by two links and is enlarged by adding one or more sticks (44). When in use Fig 34 it combines with the sitting user's feet leant on the ground. The user's feet are placed orthogonally to the feet of the apparatus. This support as well is a tetrahedron, as the one of Fig. 33 wherein only one support is completed by leaning the user's feet on the ground. In Figs. 27, 28, 29 and 30 there are some, not exclusive, diagrams concerning the positioning of the backrests (47) that can be added, or not, to the surfaces of these chairs. These backrests are constrained to the seats of the chairs and are combined as in orthopaedic corset by proper sticks (15); Fig. 7 shows one prospective of the solution of the four-legged chair. These backrests becomes stable only when the user lean his/her back on it. The sticks avoid the falling or sliding of the textile planes or the like which the backrests are made of, while the side bracing (48) of these surfaces completes their stability. In closing phase, these surfaces can be folded and aligned together with the other parts of the apparatus, also without disjoin them. In some apparatuses, as the one represented in fig. 6, the structure of a seat on three-legged chair is composed of a backrest (14) supported by a pair of sticks (15) hinged to textile materials near the two ends of the joint between poles and surface of the seat, while two other sticks (16) enlarge the seat beyond the polygonal perimeter of its supports, in order to extend the small triangular supporting surface. When the user's legs lean on these extensions (16) the side supporting planes (48) of the backrest spread, finally tightening the backrest around the user's back.

    [0017] In a not exclusive solution, the junction that hinges the structure as antiprism Fig. 36 is shaped as a polygonal ring (49) made of metal or other firm materials. The circular section of its segments functions as hinge pin to proper heads (50) made of reinforced plastic material that join to the ends of the pole (that are shaped as little tubes in this version). On the vertexes of the polygonal ring are preset some small spheres (51) that reinforce the point where the ring is mainly put under stress and enlarge the friction area between the metal and the end of the pole Fig. 37 that are made of plastic materials. This friction make the junction stable, otherwise the junction could have an inclined or distorted position. This shape of the junction enables to tighter gather the poles without spaces among them.

    [0018] An accessory for still further tighten the seats and the tables Fig. 25 concerns a means of traction (52), a rope or a band which surrounds the side traction pillars of the structure and gather them all, fastening them, by an adjustable closing (53). The said means of traction is still further stronger tightened after the opening of the apparatus. An apparatus composed of the same elements of the seat, but conceived as high chair Fig. 38, here the three-legged version is shown. It differs in an upper supporting surface, not stretched, not collaborating but relaxed downwards creating a sack (54) where to put a baby and has two lower openings for the baby's legs. Three tie straps (55) close the upper means of traction, they serves as edge, backrest and support for the sack seat, while in the lower part, on the front tie straps, there is an adjustable support (56) for the baby's feet.

    [0019] A similar structure, but more expanded Fig. 39 can contain, instead of a seat for children, a conical/pyramidal basin, made of waterproof material, with function as tub or sink (57); lower drain tap is provided (58).

    [0020] The upper surface of the apparatus with functions of a small table Fig. 40 or high table Fig. 41 is very tensed; the said surface (59) is preferably going to be made of not textile material or in any case few deformable and not elastic, thin and foldable materials. The edges of the said surface are going to be enlarged with external borders (60) in order to reinforce the sides of the table. A pole(61) leaned to the central junction, crosses the plane vertically, and by a linking ring (62) with the same plane it can adjust and compensate the falling downwards of the centre of the supporting surface of the table making flatter the said surface and suitable to sustain the heaviest objects without deforming. Above the pole emerging from the surface (63), multifunction stands can be added: Lamps, bottle and glass holders and so forth.

    [0021] The apparatus shaped as a foldable garden hammock stand Fig. 42 and Fig. 43 is composed of two junction (64), joined to the ends of a horizontal pole (65); from each junction two poles point downwards (66), and a single longer pole point upwards (67); the system of means of traction of this apparatus enables the hammock to support both transversal and longitudinal, strong stresses made by the user. In this solution the junctions (64) are tied to the head of this central and horizontal pole and hinge the other poles, in a more complex manner: two of these heads (68) are rounded and insert in some cap-shaped niches (69), as the femoral head in the hip joint. A string (70) avoid the separation in parts of the structure when the means of traction are unloosened. A further mean of traction (71) is between the extremities of the hammock, joining the base of the two junctions too (72). It is useful for stabilizing the structure of unladen and relaxed hammock and is not tightened. Unlinking or unloosening the lower tie straps (73) or mean of traction (71) it is possible to better fold the structure of the hammock by dividing in two sections the longest poles as in Fig.45 which can be sectioned into intermediate points (74).

    [0022] The structure of the camp bed apparatus Fig. 46 is quite similar to the previous one, but the poles that point upwards from the junction are two per each junction of the horizontal pole. It is a camp bed/hammock with a more tightened supporting surface. The said surface is supported by four poles on the vertexes and, as for the seats, it is part of the means of traction of the structure and, in the schematized solution, in the said surface also the shorter sides (75) of the apparatus are extended, and from these side it further extends (76) toward the opposite junction. This structure as well can be divided into fragments and the poles can be halved in two sections. In disassembly phase, the whole piece of material and the tie straps that complete it are disjoint from the frame of poles in order to simplify as much as possible the folding of the apparatus. The links among the supporting surfaces and the poles in all the apparatuses are similar to the link of the poles on the base: - a screw (77) fixes a little cap (78) to the supporting surface, to probable reinforcing straps (79) and to the small cup that surrounds the end of the pole (80).
