Description

Technical Field

[0001] This invention relates to a crib for infants and toddlers, which has a sleeping surface formed by directional tension. Background Technology

[0002] Prior applications and intellectual property documents specifically describe a novel crib without a mattress or railings, having a sleeping surface surrounded by two sidewalls in a cocoon-like structure. These surrounding sidewalls, composed of inner and outer membranes, serve both as the sleeping surface and as cushioned chambers, forming soft and comfortable sidewalls.

[0003] Although the implementation of these technologies has brought significant improvements, further improvements are still needed to perfect the lying performance of cribs. Summary of the Invention

[0004] Therefore, the object of the present invention is to solve and address the above-mentioned problems. In particular, the present invention aims to solve the problem of the upward curvature of the central portion of the horizontal surface as described in the prior art.

[0005] Furthermore, when the bed surface is subjected to load, it is necessary to prevent hammock-like deformation throughout the central region due to uneven tension in the sidewalls and converging tension at the ends of the resulting boundary endwalls (endwalls). This imbalance must be compensated for. Moreover, this uneven load should be eliminated by providing a preferred arrangement that provides uniform suspension throughout the bed surface according to the present invention. The tension walls (sidewalls, endwalls) surrounding the bed surface should be designed such that the tension walls on all sides are adapted in terms of their shape, material properties, and tension, thereby creating uniform suspension throughout the bed surface.

[0006] Finally, the purpose of this invention is to prevent changes in the static properties of the surface caused by the surrounding sidewalls (inner / outer membranes in the prior art) due to minor variations in the tolerances, properties, and elasticity of the material during sewing, especially minor variations in sewing workmanship and seams.

[0007] In one prior art construction, a supine surface is formed within a bag-shaped device. In another prior art construction, a cocoon-like design is proposed, in which a self-supporting supine surface is first formed, and then its suspension is supported by two surrounding sidewalls composed of an inner and outer membrane, forming a cushioning chamber. This raises several problems.

[0008] The drawback of the existing technology is that an independently functioning recumbent surface has been formed, which is then supported by two sidewalls consisting of an inner membrane and an outer membrane. In this case, even minor variations in the material of the sidewalls, the seams, or the pores of the membranes are sufficient to adversely affect the recumbent surface, which has already been adjusted in terms of its static properties. Furthermore, the two membranes acting as buffers increase complexity, thereby increasing the possibility of errors during balance adjustment. Another disadvantage is that the sidewalls formed by the two membranes converge at a narrower front end, thus enclosing the entire recumbent surface. Additionally, the horizontal arch slopes downwards towards the front, reducing the wall area of ​​the sidewalls converging at the ends.

[0009] As a result, only these two membrane-designed sidewalls serve as buffer chambers for the horizontal surface, providing suspension for the entire surface. On the one hand, they utilize the large surface area of ​​the sidewalls to provide elastic support over most of the horizontal surface; on the other hand, they simultaneously compensate for both the reduced horizontal surface area and the reduced wall area at the ends. This results in upward bending of the horizontal surface, hammock-like deformation under load, and uneven static characteristics and suspension issues across the entire horizontal surface.

[0010] According to the present invention, these problems are solved by an infant bed comprising a horizontal frame (101), at least one support element (103) mounted on the frame (101), at least two support elements (105a, 105b) mounted on the frame (101), a textile surface (107) stretched within the frame (101) by a fastening mechanism, two textile sidewalls (109a, 109b) stretched between the support elements (105a, 105b) and the surface (107), and two textile endwalls (111a, 111b). The textile endwalls (111a, 111b) are composed of at least two interconnected sub-elements (111a1, 111a2, 111b1, 111b2). The sub-elements are installed on the ends of the textile sidewalls (109a, 109b) and the textile surface (107) and each forms an inclined wall element. The first sub-elements (111a1, 111b1) point outward from the textile surface (107) at a first angle α, and the second sub-elements (111a2, 111b2) are arranged inward in the opposite direction at a second angle β, so that the two sub-elements (111a1, 111a2, 111b1, 111b2) form an elastic element.

[0011] The horizontal frame (107) may be integrally formed, but is particularly preferably formed of two opposing frame components that are stably connected at the ends of the frame (107) by means of connecting elements.

[0012] At least one support element (103) is mounted at the bottom, commonly referred to as a "foot" or "leg". Its design can vary; for example, it can take the form of an arched leg as shown in some of the attached figures.

[0013] At the top, the crib has support elements (105a, 105b) mounted on the frame (107), the support elements having fabric sidewalls (109a, 109b) stretched on them, as described below.

[0014] The textile mattress (107) is fastened to the frame (101) by means of fastening mechanisms, such as zippers, strip guides, etc. This is essentially for supporting an infant or toddler in a lying position. The textile mattress (107) according to the invention does not require a conventional slatted bed base, etc.

[0015] Textile sidewalls (109a, 109b) are stretched between the textile bed (107) and the support elements (105a, 105b), wherein the installation of the support elements (105a, 105b) can be achieved using the same or different fastening mechanisms.

[0016] The infant bed is surrounded by two textile end walls (111a, 111b).

[0017] The infant bed according to the invention is characterized in that, in the basic embodiment, the textile end walls (111a, 111b) are composed of at least two interconnected sub-elements (111a1, 111a2, 111b1, 111b2), which are mounted on the ends of the textile side walls (109a, 109b) and the textile surface (107), and each forms an inclined wall element.

[0018] Specifically, the first sub-elements (111a1, 111b1) are connected to the textile surface (107) at the bottom and to the ends of the textile sidewalls (109a, 109b) at the sides, particularly by sewing. The second sub-elements (111a2, 111b2) are adjacent to the first sub-elements (111a1, 111b1) at the top and are similarly connected to the ends of the textile sidewalls (109a, 109b) at the sides.

[0019] According to the invention, the first sub-elements (111a1, 111b1) extend outward from the textile surface (107) at a first angle α, i.e., away from the center toward the end of the crib. This first angle α is between 30° and 179°. Preferably, the first angle α is an obtuse angle between 91° and 179°, particularly between 100° and 179°.

[0020] On the other hand, the second sub-elements (111a2, 111b2) are arranged at a second angle β in a direction opposite to that of the first sub-elements (111a1, 111b1), i.e., facing the center of the crib. The second angle β is between 30° and 179°, preferably between 45° and 179°, more preferably between 91° and 179°, and particularly between 100° and 179°. With this arrangement according to the invention, the two sub-elements (111a1, 111a2, 111b1, 111b2) are tensioned with an elastic element. It particularly has an accordion-like structure (Z).

[0021] When an infant or toddler is placed in a conventional crib, the conventional sleeping surface either remains very stiff and therefore uncomfortable, or sags rapidly. However, according to the invention, at least two parts of the textile endwalls (111a, 111b) are provided with an elastic element that flexes to varying degrees according to the weight of the infant or toddler. This allows the tension of the sleeping surface (107) to be at least partially self-regulating.

[0022] To achieve this self-regulation, the spring forces of the textile sidewalls (109a, 109b) and the textile endwalls (111a, 111b), and optionally the textile surface (107), are coordinated with each other. This can be achieved, for example, by using textiles with specific elasticities, which may also be different from each other.

[0023] In a preferred embodiment of the infant crib, the seams between the textile sidewalls (109a, 109b) and the textile surface (107) are arranged at a predetermined distance from the mounting point to the frame (101). This arrangement according to the invention allows the textile sidewalls (109a, 109b) to be incorporated into the suspension of the surface (107) because they are not mounted on a rigid bed frame as is conventional. This advantageous improvement also facilitates self-adjustment; higher tension is generated in the textile sidewalls (109a, 109b) when the textile surface (107) bears a greater load. Furthermore, the arrangement according to the invention can compensate for manufacturing tolerances; that is, if the seams are not executed precisely, this is compensated for by the invention.

[0024] In a preferred embodiment of the infant crib, the crib further includes two crossbars (113a, 113b) fixed between the support elements (105a, 105b), wherein the at least two textile endwalls (111a, 111b) are composed of at least three sub-elements (111a1, 111a2, 111a3, 111b1, 111b2, 111b3). In this arrangement, the third sub-elements (111a3, 111b3) are arranged outward and upward at a third angle γ in a direction opposite to that of the second sub-elements (111a2, 111b2), and fixed to the crossbars (113a, 113b), thereby the three sub-elements (111a1, 111a2, 111a3, 111b1, 111b2, 111b3) form an extended elastic element. The third angle γ is between 30° and 179°, preferably between 45° and 179°, more preferably between 91° and 179°, and particularly between 100° and 179°. It also has a particularly accordion-shaped structure (Z).

[0025] This implementation improves structural stability through the crossbars (113a, 113b) and improves the distribution of tension and spring action through the textile endwalls (111a, 111b) composed of three sub-elements (111a1, 111a2, 111a3, 111b1, 111b2, 111b3). Because the textile endwalls (111a, 111b) are designed in a quasi-accordion shape, they provide even better elasticity when the surface (107) is under load.

[0026] The basic shape of the infant crib according to the invention is not fixed. However, it is preferred that the frame has a generally elliptical basic shape, as shown in the accompanying drawings illustrating the preferred embodiment. This elliptical shape, as well as the circular shape, has the advantage that air does not accumulate in the corners, thereby ensuring that the climate remains generally uniform across the entire textile bedding surface.

[0027] In a further improvement, it has proven advantageous for the specific design of the textile sidewalls (109a, 109b) that the two support elements (105a, 105b) extend in an arched shape between the two end faces of the frame (101). In this case, the two support elements (105a, 105b) are secured using the same or similar fasteners used to fix opposing frame components to each other. In this way, starting from the arched seam (115a, 115b) between the textile facet (107) and the textile sidewalls (109a, 109b), the textile sidewalls (109a, 109b) are concavely stretched by the upwardly arched support elements (105a, 105b) and the two textile end walls (111a, 111b).

[0028] In addition to further optimizing the tensile strength under load, these concavely stretched textile sidewalls (109a, 109b) have a soothing effect on infants because the shape formed according to the invention mimics the womb, thereby creating a sense of security. Due to the tensile strength distributed according to the invention, the textile sidewalls (109a, 109b) remain as flexible as the environment of an unborn fetus in the womb.

[0029] To better realize the advantages of the invention, the fabric of the textile surface (107) and / or the textile sidewalls (109a, 109b) and / or the textile endwalls (111a, 111b) is at least partially elastic and at least partially breathable. Different textiles with varying degrees of elasticity can be used depending on the size of the infant or toddler and the resulting increased weight. This is made possible, in particular, by the aforementioned fastening mechanism, which allows for easy replacement of the textile components of the crib. The at least partially breathable nature is also important for providing sufficient fresh air to the infant or toddler.

[0030] In a further embodiment, it has proven advantageous that the fabric of the textile facet (107) and / or the textile sidewalls (109a, 109b) and / or the textile endwalls (111a, 111b) contains functional fibers and / or functional particles. In particular, the functional fibers and / or functional particles may have electromagnetic shielding properties. Similar to a Faraday cage, infants or young children can be protected, for example, from 5G radiation and general electromagnetic pollution. Examples include fibers or particles made of silver or containing silver ions. However, care must be taken to ensure that these functional fibers and / or functional particles are arranged in a manner that prevents direct contact with infants or young children.

[0031] In one embodiment, the infant bed further includes a circumferential textile wall (117) disposed on the edge of the textile surface (107) or the frame (101) and extending at least to the outside of the textile sidewalls (109a, 109b), thereby forming a gap (119) between the circumferential textile wall (117) and the textile sidewalls (109a, 109b). The circumferential textile wall (117) has no structural effect on the infant bed of the present invention or on the specific distribution of tension. Instead, it serves as a protective covering and enhances the appearance from a non-technical perspective. The fabric of the circumferential textile wall (117) may also contain functional fibers and / or functional particles, wherein these functional fibers and / or functional particles have electromagnetic shielding properties. In the case of the circumferential textile wall (117), it is ensured in all cases that the infant or toddler does not come into contact with the functional fibers and / or functional particles.

[0032] The textile surface (107), in combination with the textile sidewalls (109a, 109b) and the textile endwalls (111a, 111b), is in principle sufficient to provide very good lying comfort for infants or toddlers. However, this can be further enhanced if the crib according to the invention also includes a mattress (121) arranged on the textile surface (107), the mattress being shaped to fit the shape of the textile surface (107). To achieve the above advantages, the mattress (121) is designed to be at least partially breathable. When the term "mattress" is used herein, it includes any form of mattress, pillow, or cushion, provided that the features of the invention are present and the corresponding effects are achieved.

[0033] The textile sidewalls (109a, 109b) fit snugly against the mattress (121) without any gaps between them. In this way, the mattress (121), together with the surrounding textile sidewalls (109a, 109b) and textile endwalls (111a, 111b), forms a breathable unit. This enhances comfort, such as when the mattress comes into contact with urine or feces, as the mattress is easily replaceable. The mattress can be simply removed and cleaned without disassembling the textile components, which are designed like a cocoon.

[0034] Specifically, the mattress (121) is designed to be semi-permeable, preventing moisture from reaching the textile surface (107) through the mattress (121), while allowing air to flow over the mattress (121) from below. The mattress (121) may also contain functional fibers and / or functional particles, wherein these functional fibers and / or functional particles have electromagnetic shielding properties. To ensure that infants or young children do not come into contact with the functional fibers and / or functional particles, these are preferably arranged on the lower surface of the mattress (121).

[0035] As described above, the textile components of the crib are at least partially breathable. As an alternative to a semi-permeable design, the mattress (121) may consist of two components, with an impermeable layer on the lower surface and breathable portions covering the sides and surface. Thus, the mattress (121) is impermeable at the bottom in all cases, but retains at least some of the breathability of the crib through its surface and sides.

[0036] In a further embodiment, this feature is utilized, wherein the infant bed further includes at least one air cushion (123) for supplying air to the infant bed, wherein the at least one air cushion (123) is arranged to the side and / or below the textile surface (1047) and is in fluid communication (127) with an air filter (125).

[0037] The supply of filtered and / or purified fresh air significantly contributes to the infant's peaceful sleep and, in the case of Sudden Infant Death Syndrome (SIDS), safe sleep. The at least one air cushion (123) is arranged in a manner that does not generate actual airflow, but rather allows air to flow slowly into the crib according to the invention. The air cushion (123) may, for example, be arranged on the fabric sidewalls (109a, 109b), particularly within the gaps (119), allowing fresh air to flow in from the sides. The circumferential textile wall (117) may be made slightly less airtight, so that fresh air flows substantially into the crib of the invention without escaping outwards. (Stale) air flowing back into the gaps (119) in a balanced state can be discharged to the outside.

[0038] The at least one air cushion (123) may also be arranged, for example, below the textile bedding (107), allowing fresh air to flow in from below. A combination of lateral and under-side inflow is also possible. Particularly preferred is that the inflow of fresh air into the crib forms slowly rising fresh air bubbles that carry away stale air and are replenished by the air cushion (123).

[0040] Figure 1 (Does not exist) Figures 2 to 17 The specific implementation details are described below. Detailed Implementation

[0041] exist Figures 1 to IX In the figures, the same parts are represented by the same reference numerals; however, for clarity, not all reference numerals are necessarily included in all figures.

[0042] Figure I A schematic side view of a crib according to a preferred embodiment of the invention is shown. In this embodiment, the horizontal frame 101 is supported by two downwardly curved legs as support elements 103, the legs also having feet (not reference numerals) for stabilization. These feet are removable, allowing the crib to be converted into a cradle in a few simple steps.

[0043] Two support elements 105a and 105b (105b not shown here) are mounted on the frame 101 and also extend upward in an arched shape; together with the surface 107 (not shown here), they support the fabric sidewalls 109a and 109b (109b not shown here). Two crossbars 113a and 113b are installed between the support elements 105a and 105b (105b not shown here), and the textile endwalls 111a and 111b are stretched between the two crossbars 113a and 113b, shown only schematically here. Reference numeral Z indicates the accordion-like structure of the elastic element.

[0044] Figure II schematically shown Figure IThe illustration shows a front view of a crib according to a preferred embodiment of the invention, presented in a semi-transparent manner to show the various seams between the components. A surface 107 is laid within the frame 101, and textile sidewalls 109a, 109b extend from the frame via arched seams 115a, 115b to the support elements 105a, 105b. In the foreground is a textile front wall 111a, shown in this embodiment with its three sub-elements 111a1, 111a2, 111a3. This textile end wall 111a is stitched to the surface 107 at the bottom via sub-elements 111a1 and to the crossbar 113a at the top via sub-elements 111a3. The elastic properties of the textile end wall 111a are indicated only by the arched seams.

[0045] Figure III A schematic 3D diagram is shown. Figure I and Figure II The illustration shows the infant bed of the present invention. This type of illustration clearly shows the accordion-shaped textile front wall 111a of the present invention, whose sub-elements 111a1, 111a2, and 111a3 are arranged at different angles to each other. It is also clear how the cocoon-like structure formed by the textile walls 109a, 109b, 111a, and 111b, together with the downwardly sloping surface 107, is effectively “suspended” within a frame structure including the frame 101, support elements 105a and 105b, and preferably crossbars 113a and 113b. In addition to the illustration of the infant bed, arrows indicate various tensions acting on the surface 107, and the sub-elements 111a1, 111a2, 111a3, and sub-elements 111b1, 111b2, and 111b3 are shown, particularly to illustrate the accordion-shaped design of the textile end walls 111a and 111b. Angles α, β, and γ are also shown here.

[0046] Figure IV and Figure V These are schematic exploded views of the textile wall, viewed from the front and from a perspective. To achieve optimal distribution of tension, the shapes of these individual components are optimally coordinated with each other. Furthermore, the shape of the individual components according to the invention has a decisive influence on the formation of the concave structure of the two textile sidewalls 109a, 109b.

[0047] Figure VI A schematic front view of the cocoon formed by textile walls 109a, 109b, 111a, and 111b is shown. This illustration again serves to clarify the arrangement of the textile front wall 111a and its sub-elements 111a1, 111a2, and 111a3 relative to the textile side walls 109a and 109b. It can also be seen that the arched seams 115a and 115b are spaced apart from the mounting points on the frame 101 (not shown here).

[0048] Figure VI The cocoon shown is in Figure VII The diagram shows a schematic perspective view of the textile end walls 109a, 109b, 111a, and 111b, as a preferred embodiment of the invention. The diagram is rendered semi-transparent, allowing the rear textile end wall 111b to be seen in addition to the front textile end wall 111a. Although the angles between the sub-elements 111a1, 111a2, 111a3 and 111b1, 111b2, 111b3 and the horizontal surface 107 are not shown here, the geometric relationships between the individual components used to generate various tensions and to adjust them are still clear.

[0049] As described above, from a structural point of view, the fabric walls 109a, 109b, 111a, and 111b, together with the facing surface 107, form a self-regulating system. In this system, the tension of the fabric sidewalls 109a, 109b and the facing surface 107 is self-regulating; that is, when the tension on the facing surface 107 increases, the fabric sidewalls 109a and 109b are stretched into a curved shape. This is due to the shorter direct path from the facing surface 107 to the support elements 105a and 105b. Therefore, due to the (relaxed) curvature, the fabric sidewalls 109a and 109b bear less tension, while the facing surface bears greater tension.

[0050] In the event of minor static changes or deviations, the face 107 is less taut, causing the textile sidewalls 109a, 109b to be pulled into bending less, and thus to be stretched more taut. This results in a constant spring force within the face 107 due to the self-adjustment of the textile sidewalls 109a, 109b, 111a, 111b, even with minimal variation in the type of fabric used, the relative fit and seam design, or the correct cut of the fabric. Furthermore, elastic zippers or clips can be used to attach the fabric to the frame 101, the support elements 105a, 105b, and / or the crossbars 113a, 113b to aid in self-adjustment.

[0051] The horizontal tension applied by the surface 107 causes the textile walls 109a, 109b, 111a, and 111b to bend into a nearly 360° elliptical shape, thus creating a cushioning effect with the soft textile sidewalls 109a and 109b surrounding the surface 107. In this embodiment, the arching in the textile sidewalls 109a and 109b and the spring force in the surface 107 are not generated by two conventional sidewalls as in the prior art, but by two different but self-regulating tension directions and forces.

[0052] Figure VIIIA schematic perspective view shows the cocoon-shaped textile walls 109a, 109b, 111a, 111b together with the circumferential textile wall 117. The cocoon is shown in cross-section here, making the gap 119 visible. A preferred embodiment of the invention includes a mattress 121 disposed within the textile walls 109a, 109b, 111a, 111b and adapted to the sleeping surface, which is elliptical in a particularly preferred embodiment.

[0053] Further specific embodiments involve the setting of the air cushion 123, such as... Figure IX A schematic front view is shown. As previously described, these air cushions 123 are used to supply fresh air to the infant crib of the present invention. For this purpose, the air cushions 123 can be arranged in various locations. One option is a lateral arrangement, preferably within the gap 119, such that fresh air from the air cushion 123.1 is introduced through the textile sidewalls 109a, 109b. Alternatively, fresh air can also be introduced via the air cushion 123.2, which is arranged below the gap 119 and introduces fresh air through the gap 119 and the textile sidewalls 109a, 109b.

[0054] A third alternative includes an air mattress 123.3 positioned beneath the sleeping surface 107, through which fresh air flows into the interior of the crib. If a mattress 121 is provided in this particular embodiment, it, like the sleeping surface 107, is also designed to be breathable.

[0055] As from Figure IX As can be seen, the air filter unit 125 can be conveniently positioned directly beneath the crib, thereby communicating with the air mattress 123 via the fluid communication portion 127. To protect the infant or toddler from radiation / electromagnetic pollution that may emanate from the air filter unit 125, it has proven advantageous that at least the sleeping surface 107 is provided with functional fibers or functional particles to ensure shielding. The mattress 121 and the textile walls 109a, 109b, 111a, 111b can also have such a functionalized structure.

[0056] The following, combined with further Figures 2 to 17 This description will further elaborate on several aspects of the invention. In this description, reference numerals that differ in certain cases are used; the correspondences of these reference numerals can be identified from the numeral list and reference table appended at the end.

[0057] In one embodiment of the present invention, the face 107 is formed by two tension walls (the aforementioned face 107 and textile sidewalls 109a, 109b). Tension wall 1 (hereinafter referred to as face 107) is horizontally stretched, and tension wall 2 (hereinafter referred to as textile sidewalls 109a, 109b) is vertically stretched. These tension walls 107, 109a, 109b are configured to interact with each other to form face 107. Thus, even if possible changes occur in the seams, materials, or shapes (stamping) of tension walls 109a, 109b, due to the special arrangement and design of tension walls 1 (i.e., 107) and tension walls 2 (i.e., 109a, 109b), tension walls 107, 109a, 109b can balance each other, so that face 107 always has the same desired elasticity.

[0058] In a preferred embodiment of the invention, improved structural stability is achieved by preferably at least four functional tension walls 109a, 109b, 111a, 111b, preferably with each pair of tension walls being identical in shape, function, design, and tensile strength. Preferably, two identical tension walls 109a, 109b are mounted on opposite left and right sidewalls (configuration A). Preferably, two further novel functional tension end walls 111a, 111b with identical configurations are formed and mounted on opposite front and rear ends (configuration B).

[0059] This novel functional design, comprising components A and B, ensures uniform elasticity across the entire surface 107, and coordinates with the arrangement defined by frames 101, 105a, 105b and the surface 107 in terms of elasticity. Figures 2 to 17 In this diagram, all identical components are labeled with the same reference symbol; however, for clarity, not all reference symbols are necessarily included in all figures. Nevertheless, individual reference symbols may be used in different ways.

[0060] Figures 2 to 7 The description relates to a preferred embodiment of the functional tension wall of the present invention. The advantages over the prior art arise from two tension walls that are balanced with each other. Figure 2 In A, A represents the sleeping surface within the frame of the infant crib. To form the sleeping surface, it is preferable to tension the elastic material in a manner that creates a load-bearing yet resilient surface. Due to the circular arrangement of the frame, all tensions A1 are aligned in the same direction.

[0061] exist Figure 2In the designation C, C represents the bed surface, which is preferably elliptical. B1 represents the crib frame, which is also elliptical. C1 and C2 are tension forces applied to the elastic material in a manner that creates a load-bearing yet resilient bed surface. Tension forces C1 and C2 differ from other tension forces. This is because the narrow, tapering ends of the crib, in contrast to the larger central area, require different tension forces to form uniform static units within the bed surface. Tension force C1 must be designed to be stronger than tension force C2, which supports the smaller, tapering bed surface, because it must provide greater static stability over a larger area than tension force C2.

[0062] exist Figure 3 In A, construct and Figure 2 The same static unit as C. The only difference is that the bed frame is rectangular. Figure 4 Two diagrams are shown, illustrating the two directions of tension: horizontal and vertical. The vertical tension... Figure 4 The vertical tension B is represented by B. Figure 2 and Figure 3 The horizontal tensions (tensions A and C) together form a combined tension and a horizontal surface stabilized by two tension walls.

[0063] Figure 5 A shows in Figure 4 The description refers to the combined tensile force. This is the combined tensile force generated by the vertical tensile force C and the horizontal tensile force F. The resulting horizontal surface is B. Figure 5 In A1, the tension F1 generates a stronger pull. As a result, the vertical tension and the sidewall C1 are stretched into a bent shape. Furthermore, the resultant tension R1 shifts in the direction of the horizontal tension. This shape-forming, forced bending of the vertical sidewall... Figure 7 Detailed explanation follows.

[0064] Figure 6 A side view is shown. This side view shows a stronger horizontal tension force (represented by F1) and a vertical tension wall C pulled outward (in the direction of the horizontal tension force F1). As a result, the vertical tension wall C, which was originally designed to be straight, is stretched into a curved shape C1. This newly formed tension wall C1 bends its inner side toward the horizontal surface B1 and is pulled toward the outer frame by the horizontal tension force F1. The newly formed horizontal surface B1 is formed by the stronger tension force F1 and the bending tension C1.

[0065] However, this embodiment of the invention is based on the following feature. The horizontal surface B1 formed by the two tension walls C1 and F1 is self-adjusting and self-correcting even if the material of the sidewalls, the stitching, or the stamping of the cocoon-shaped components changes. This is because, when the sidewall C1 is pulled into a bend, the greater the tension applied by the horizontal tension F1, the greater its elastic force and the smaller its tension.

[0066] When the tensile force F1 is weak, the sidewall C1 pulled into the bend has a weaker elastic force, resulting in a straighter profile and a greater tensile force. In this way, the imbalance of tensile forces is self-adjusted, and through the interaction of tensile forces, the desired elasticity, stability, and structural integrity are consistently generated in the horizontal surface B1.

[0067] Figure 7 This section details the forced bending of the sidewalls and the interaction between the two tension walls (vertical and horizontal). In the functional sequence shown in A, the two tensions F1 and F2 form a resultant tension R. In B, the bending of the frame is shown. Its oval and ovate surfaces, combined with the aforementioned two tensions, support and reinforce the vertical tensions on the sides / the bending shape of the sidewalls. The bending C resulting from all these components is formed by the tensions F1, F2, the resultant tension R, and the frame bending described in B.

[0068] Figures 8 to 17 The description relates to the implementation of two functional tension wall systems of the present invention. Figures 8 to 17 The improvements are shown. Figure 8 In this structure, a bed surface 3 is formed, consisting of two identical, opposing wall systems, namely System 1 and System 2. These two wall systems function harmoniously with each other and adapt to existing structural requirements within their respective systems. Wall system 1, with its large area, supports the large bed surface requiring cushioning. Wall system 2 is located in the narrower areas of the bed surface and at the ends of the inclined horizontal arches of the bed frame. These wall systems adapt to the structural requirement of a taut, smaller bed surface.

[0069] Therefore, wall system 1 and wall system 2 function harmoniously. Wall system 2 must exhibit highly elastic properties. This is because a smaller, tapering support surface is needed to cushion the impact, and the downward-sloping horizontal arches at the ends limit the length of the wall system, thus limiting its elastic force.

[0070] Figure 9 The solution for wall system 2 is shown. The horizontal surface X is well cushioned in the center by the large surrounding sidewalls 1. In order to achieve the tapered ends with shortened walls (due to the inclined frame) in a manner that is equally soft and statically adaptable in terms of cushioning, a functional system wall (wall system 2) is employed according to an embodiment of the invention.

[0071] The system wall (corresponding to textile end walls 111a and 111b) consisting of 2, 2.1, and 2.2 (corresponding to sub-elements 111a1, 111b1, 111b3, 111a2, 111b2, and 111b3) is an arrangement of various wall segments that function as a single wall through stitching. As explained in A, this wall has a fixed length, the same as wall 1. Therefore, it can elastically compensate for structural forces at the ends along its entire length. However, in order to precisely fit into the shape of a bed frame with an inclined horizontal curve, as explained in B, a serrated wall is formed that functions in a manner comparable to an accordion or a coil spring. The advantage of this functional system wall is that its length, and consequently its elasticity, is fixed. However, thanks to its serrated design, it can still be configured within a smaller predetermined space.

[0072] Figure 10 A preferred embodiment of the system wall is shown. The serrated system wall is composed of a vertically outward pulling force 2, a vertically inward pulling force 3, and a vertically outward pulling force 4. Thus, the horizontal pulling force 1 is imparted to a flexible suspension through the system walls 2 / 3 / 4.

[0073] Figure 11 This section explains all the functions of the system tension walls and the interaction of the lateral tension walls. In A+G, the aforementioned sidewalls and their systematic tension function are explained in relation to the frame. As a result, the inwardly curved sidewalls provide excellent cushioning for the supine surface of cocoon X. In B, B1, and B2, tensile forces are shown, which are shortened along their entire length B2 by the serrated shape B1.

[0074] This is also reflected in the design (B1, B2). Specifically, the height (within frame G) of the functional walls and the actual length Y of the functional walls, also explained in B3. In Y and X, the elongation force of the system walls is explained through elasticity. The system walls extend below the X-axis solely through elasticity causing the individual walls to elongate. This is the suspension mechanism resulting from the elongation of the individual walls caused by the elasticity of the material.

[0075] In diagram C, the elastic effect of the system walls is shown by increasing the angle between them. Due to the serrated design, an angle of 45° is formed, for example, in a static, unloaded state. Under load, this angle expands to over 45°, for example, over 50°. Thanks to the serrated design and the elastic material, the resulting system walls exhibit extremely flexible elasticity, making them ideally suited for static balance adjustment of tapered surfaces.

[0076] The label B in the diagram indicates the material used in the tension wall. Because the system wall mounted thereon not only elastically deforms downwards but also elastically deforms as a single unit along with the large sidewalls, the material is also stretched laterally. This generates a lateral tension S, which, through its elasticity, effectively reduces the downward tension S1. The force acting laterally relative to the tension S persists even without load. Therefore, it is important to create an extremely flexible suspension in the system wall at the ends by implementing the methods described in B and C.

[0077] exist Figure 12 Section 3.6 describes the various loads, namely F0 (no load), F1 (medium load) and F2 (high load). Figure 12 Figure 3.5 shows how the horizontal surface X is elastically pulled downwards by opening the angle and elongating the system wall section.

[0078] Figure 12 sub Figure 12 .1 indicates that this elastic action is crucial for balance adjustment. There exists a long X-axis and a horizontal plane of width Y located at the center. The Y-axis and X-axis, intersecting at the ends, are narrowed within the horizontal plane without the use of functional walls, thus limiting their elastic force. The sub-axis in this figure... Figure 2 , 3 The sequence of 4 and 5 illustrates the respective functions of sidewalls 2 / 4 and the functions of the end functional walls 3 / 5. The unloaded state of the horizontal surface is... Figure 12 As shown in 2 and 3, the load conditions are shown in 4 and 5.

[0079] Figure 13 , Figure 14.1 , Figure 14.2 and Figure 14.3 Various implementations of possible arrangements of infant beds, frames, and functional walls are shown. Figure 14.2 This invention illustrates a baby crib that visually imitates existing technology only. Functionally, the system walls of this invention remain in the inner region, while the outer walls are retained only to achieve preferred and highly beneficial ventilation. That is, the outer walls are installed but do not function in terms of force, or only slightly.

[0080] Figure 15 Three top views A, B, and D illustrate the effect of tension and the structure of the tension wall system. View C shows a holographic depiction of the tension wall. In sub-view A, the large, opposing tension wall shown in 1 acts as a buffer against the horizontal surface 3. 2 shows a smaller system tension wall (zigzag, accordion, elastic tension, wall system) that, in order to form / provide the same suspension for the horizontal surface 3 and allow the horizontal surface to settle / elastically deform uniformly under load, must have the same elastic force as the system tension wall shown in 1.

[0081] In B, the tension wall of the sidewall is denoted as 1, and the tension wall of the endwall system is denoted as 2. Furthermore, the tension generated by the force between the intersecting tension walls (1, 2) is denoted as 3. These tensions, denoted as 3, are intended to form a uniformly acting tension force throughout the entire circumference of the surface. D shows the longer X-axis and the shorter Y-axis, and the tensions derived from them, which, in their interaction, form a uniform suspension throughout the entire surface.

[0082] C illustrates a layout depicted holographically and a preferred embodiment of the design and configuration of the two tension wall systems. The horizontal surface 6 is formed by two longitudinal tension walls 1 and 2, and corresponding end tension walls consisting of a systematic functional wall (a sawtooth suspension accordion). The end tension walls are composed of vertically generating balancing adjustment components 3, 3.1, and 3.2, and preferably support sides, indicated by 5 and 5.1, connecting the two wall systems to each other.

[0083] Figure 16 The various components that together form the structural framework of the entire cocoon are shown. Here, 1 represents horizontal tension, and 2 represents vertical tension (stretched into a curved shape as explained). Furthermore, 6 represents the horizontal surface, and 4 represents the system wall. These are further broken down into sections 5.3, 5.2, 5.1, and 5 to illustrate the lateral tensions and connections within the wall system in more detail. Thus, the tension wall (end wall system) provides vertical suspension adapted to the side walls, and connects the end walls and side walls within the harmonized structural system.

[0084] Figure 17 A possible suspension mechanism is shown, which is preferably mounted to the frame at point A and used to fix the cocoon structure at point A1. B is a suspension system for supporting various tensions under load. Furthermore, B can adjust its tension and suspension via manual operation (e.g., a helical mechanism, but not limited to this).
