BACKGROUND OF INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a bedding, more particularly a kind of three-dimensional shaped bedding with predefined continuous curve.

[0003] 2. Description of the Prior Art

[0004] Average person spends a third of their life sleeping, which makes the comfort of bedding particularly important. But bedding with warm covering that feels comfortable when you lie down is not necessarily good bedding. The fabric used for the facing, content material, weaving method and colors are all key factors affecting the quality of sleep. Good choices of mattress, padding, bed sheet, pillow and blanket can be beneficial to health, and exquisitely designed and good quality sheets, blanket cover, pillow case, and bed spread are a way of life that provide relaxation and comfort to sleepers.

[0005] Mattress and blanket are the first things to consider in the choice of bedding. The selection of mattress should first determine the size desired, and then try it out. Good mattress should keep the spine in natural and relaxed state, which in combination with warm and soft blanket, gives the sleepers comfort and a sense of satisfaction. Sleeping bag is an alternative for modern people. The working principle of sleeping bag is to create non-flowing air with a layer of inflated filler, which wraps the user in an accommodation space to cut down the contact with outside environment. When the cool air outside is kept out and the human body produces thermal convection, the body temperature can be maintained, hence keeping the user warm. The design of sleeping bags available on the market has typically mummy style that comes with a head cover and a taper shape to conform to the shape of human body. The side of the sleeping bag has a zipper to make in and out easier. Such sleeping bag design is good for heat retention. There are also envelop-shaped sleeping bag that is both comfortable and may be unzipped to be used as a blanket.

[0006] For the convenience of usage and storage, sleeping bags are usually made of certain materials and have fixed thickness and simple style. In order to accommodate the shape of human body, the design of sleeping bag basically confines body movement. Thus it may not be suitable for all kinds of circumstances. The proximity of sleeping bag interior to the body keeps the body warm, but it sometimes makes the user feel stuffy and even damp when perspiration damps the bag.

[0007] It is common for small children in kindergarten and nursery to take a nap during lunch break. Because schools usually do not have bedroom for children, they would prepare sleeping bags and have the children sleep on classroom floor. The conventional sleeping bag is monotonous in appearance and confines the movement of typically energetic teenagers or small children. The sultry feel it causes also makes it less popular with users. In this plural society, a bedding will become popular and garner more market share if it also offers other functions in addition to providing comfortable sleeping environment.

SUMMARY OF INVENTION

[0008] The primary object of the present invention is to provide a three-dimensional shaped bedding, which is formed in one piece through pressure molding of special materials to achieve the effect of a continuous curve.

[0009] Another object of the present invention is to provide a three-dimensional shaped bedding, which is formed in one piece and restores its three-dimensional shape when used to achieve the effect of easy storage and use.

[0010] A further object of the present invention is to provide a three-dimensional shaped bedding, which forms a shape of continuous, three-dimensional curve through the design of a covering member to offer bigger accommodation space and aesthetic effect.

[0011] Yet another object of the present invention is to provide a three-dimensional shaped bedding, which achieves the effect of a play tool for children through the design of different three-dimensional shapes of covering member.

[0012] Yet a further object of the present invention is to provide a three-dimensional shaped bedding, which can have varying accommodation sizes through the design of covering member into different style patterns to allow young children to hide inside for game playing and give them a sense of security.

[0013] To achieve the aforesaid objects, the present invention provides a three-dimensional shaped bedding, comprising a confining member and a covering member. The confining member encloses a predefined plane. The covering member is connected with the confining member in such a way that the predefined plane is situated on one side of the covering member. The covering member has at least an opening and at least one apical surface. The apical surface is one height apart from the confining member to turn the covering member into a shape of predefined continuous curve and make the apical surface essentially the highest point. The covering member may be folded up through exertion of force, and when the force is removed, restores the shape of predefined continuous curve.

[0014] To achieve the aforesaid objects, the present invention provides another three-dimensional shaped bedding, comprising at last a covering member and at least a frame member. The covering member has a structure of predefined shape. The frame member further consists of a top surface and a bottom surface, which is a height apart from each other. The top surface has a structure corresponding to the covering member. When the frame members props up the covering member, the covering member and the frame member form an accommodation space through the height and exhibit a structure of predefined shape.

[0015] To achieve the aforesaid objects, the present invention provides yet another three-dimensional shaped bedding, comprising a padding member, at least a covering member, a shaping member, and at least a frame member. The padding member may be laid on a flat surface. The covering member is connected to the periphery of padding member, and the part of periphery that is not connected forms at least an opening. The shaping member is connected with the covering member and protrudes from the outer rim surface of covering member. The frame member is arranged on the padding member to prop up the covering member to a height away from the padding member and form an accommodation space.

[0042] Referring to FIGS. 1A and 1B which show the structural views of three-dimensional shaped bedding according to a first and a second embodiment of the invention, the three-dimensional shaped bedding 1 comprises: a confining member 11 and a covering member 12. The confining member 11 encloses a predefined plane 13. In a preferred embodiment, the predefined plane 13 is oval shaped, which can also be round shaped. The covering member 12 is connected with the confining member 11 in such a way that that the predefined plane 13 is situated on one side of covering member 12. The covering member 12 has at least an opening 14 and at least one apical surface 15. As shown in FIG. 1A, the opening 14 is arranged at one end of covering member 12 that allows the user 2 to pass through and enter the three-dimensional shaped bedding 1. As shown in FIG. 1B, the three-dimensional shaped bedding 1a has an opening 14a situated at the central part of covering member 12a.

[0043] The apical surface 15 is one height H1 away from the confining member 11 to turn the covering member 12 into a shape of predefined continuous curve and make the apical surface 15 essentially the highest point. In a preferred embodiment, the covering member 12 displays a semi-oval sphere, which can also be hemispherical in shape. The covering member 12 is fabricated by pressure moulding of foam and non-woven fabric, hence can be made in one piece. The covering member 12 has elasticity, hence can be folded up under the exertion of force. The confining member 11 is at least a cord or at least an elastic band. When the confining member 11 is pulled, it will draw covering member 12 close in alignment with it and the covering member 12 can be folded up for storage. But when the force is removed, the covering member 12 restores the shape of predefined continuous curve.

[0044] The other preferred embodiments described below have identical or similar elements to those described earlier. Those elements are assigned the same numeral (with only a English letter suffix for distinction purpose) and names and their detailed constitutions will not be elaborated. FIGS. 1C.about.1E show the side views of several embodiments of three-dimensional shaped bedding according to the invention. As shown in FIG. 1C, the three-dimensional shaped bedding 1b further comprises a plurality of frame members 16 arranged inside the covering member 12b in a predetermined manner. The frame member 16 consists of at least two arc curves 161, at least an overlapping end 162 and two adjoining ends 163. The two adjoining ends 163 adjoin the confining member 11 respectively and the overlapping end 162 is situated exactly on the apical surface 15. As shown in FIG. 1D, the frame members 16a of the three-dimensional shaped bedding 1c are sewed to the covering member 12c, and the frame member 16a is roughly the shape of a honeycomb composed of a plurality of hexagons. Naturally, the frame member 16a can also be wavy or other shapes. In FIG. 1E, the confining member 11 of the three-dimensional shaped bedding 1d is further connected to a padding member 18 with a connecting member 17. The padding member 18 is the predefined plane enclosed by the confining member 11, and the connecting member 17 in this embodiment is a zipper so the confining member 11 and the padding member 18 may be separated in an open state or zipped up in a closed state in the internal space of the three-dimensional shaped bedding 1d.

[0045] Please refer to FIGS. 1F and 1G, which are structural side views of the three-dimensional shaped bedding according to the sixth embodiment of the invention under two different operating conditions. The three-dimensional shaped bedding 1e further comprises an extending part 19.
