2. Description of Related Arts
A conventional baby furniture, such as a baby bed, generally comprises a mattress frame embodied as a baby bed for the baby to be rested thereon. However, this kind of conventional baby furniture obviously suffers from several undesirable discrepancies.
Accordingly, the mattress frame generally comprises a supporting board and a cushion layer overlapped on the supporting board for the baby to lie thereon. However, the supporting board, which is made of wood or other rigid material, tends to be extremely inflexible. It is worth to mention that the weight of the baby is substantially supported by the rigid supporting board. As a result, depending on the quality of the mattress frame, it would rather be too soft or too hard for the purpose of supporting a baby. As a matter of published medical opinions, a mattress frame for the purpose of supporting a baby should neither be too soft nor too hard, in that if that is the case, it is liable to adversely impede normal growth and development of a baby's backbone. In relation to this discrepancy, if the parents eventually found that the mattress frame is not suitable for their baby, especially when the baby rapidly grows up, he would be left no option but to replace a new one. In other words, the parents need to spend extra money in picking another though not necessarily a better one.
In terms of weight, the conventional mattress frame inevitably bears considerable amount of weight. From engineering point of view, in order to provide secure support to the baby, rigid and strong materials have to be employed so that the strength of the overall baby bed can be guaranteed. These rigid and strong materials inevitably increase the overall weight of the mattress frame. As a result, it is a conflict between the overall weight of the mattress and the provision of a secure and strong supporting structure. Those skilled in the art, as a matter of fact, prefer the latter at the expense of the former. There is nothing intrinsically wrong to prefer safety, however, one should not simply to ignore the other side of the tension so that the relevant area of technology could be further developed.
In addition, the mattress frame is not designed to be portable so that they are inconvenient to transport and store. As a matter of fact, some sorts of foldable baby beds have been developed to address this problem. However, they generally suffer from other problems of insecure or unsafe structure, being still bulky when folded, complicated folding mechanism, and/or shorter life span.
A main object of the present invention is to provide a foldable mattress for a baby furniture, which utilizes air as a supporting medium so that the foldable mattress functions as an air cushion for providing optimal support corresponding to the weight of the baby.
Another object of the present invention is to provide a foldable mattress for a baby furniture, which utilizes air as a principal supporting medium, so that it provides better supporting performance than such conventional supporting mediums as strains, foams, springs, and the likes.
Another object of the present invention is to provide a foldable mattress for a baby furniture, wherein the foldable mattress can be easily unfolded for transportation and storage purpose and folded for usage, so as to enhance the portability of the foldable mattress.
Another object of the present invention is to provide a foldable mattress for a baby furniture, wherein the foldable mattress has an inflatable frame capable of being adjustably inflated with a predetermined amount of air, so that the supporting performance, such as hardness and conversely, softness, of the foldable mattress can be selectively adjusted by means of air pressure corresponding to the weight of the baby.
Another object of the present invention is to provide a foldable mattress for a baby furniture, wherein the foldable mattress comprises a plurality of supporting platforms formed on the inflatable frame to form a supporting surface for the baby to lie thereon, so as to overcome such discrepancies of inflexibility and instability as mentioned in the background of the present invention.
Another object of the present invention is to provide a foldable mattress for a baby furniture, wherein the folding operation of the foldable mattress is quick and easy that by simply deflating the inflatable frame so as to collapse and fold the foldable mattress into a compact structure for transportation and storage purpose.
Another object of the present invention is to provide a foldable mattress for a baby furniture, wherein the adjustment of the supporting performance, such as hardness of the foldable mattress, can be accomplished easily and conveniently by the parents without rearranging any related objects in the vicinity of the baby furniture/the foldable mattress. In other words, the foldable mattress is capable of providing maximum convenience to the parents.
Another object of the present invention is to provide a foldable mattress for a baby furniture, which utilizes air as a supporting agent, so that the foldable mattress is capable of providing secure support to the baby, yet not requiring substantial weight for maintaining its stability, as in the case of the conventional baby furniture. In other words, the present invention resolves the inherent tension between weight and rigidity and security as mentioned in the above discussion of prior arts. Moreover, the foldable mattress, which depends on air as a supporting medium, is light and therefore easy to be transported.
Another object of the present invention is to provide a foldable mattress for a baby furniture, which does not involve any complicated mechanical components or processes for its operation, so as to minimize the manufacturing cost of the present invention. After all, the main supporting medium utilized in the present invention, air, is free for all.
Accordingly, in order to accomplish the above objects, the present invention provides a foldable mattress for a baby, comprising:
an inflatable supporting frame for retaining a predetermined air therewith; and
a reinforcing frame, which is supported on the inflatable supporting frame, comprising a plurality of reinforcing platforms each having a top platform surface, wherein when the inflatable supporting frame is deflated, the reinforcing platforms are adapted to be overlappedly folded up to form a compact unit, and when the inflatable supporting frame is inflated, the top platform surfaces of the reinforcing platforms are reinforced to correspondingly align on the inflatable supporting frame to form a flat resting surface for the baby to lie thereon, while the inflatable supporting frame functions as an air cushioning support for substantially supporting a weight of the baby.
These and other objectives, features, and advantages of the present invention will become apparent from the following detailed description, the accompanying drawings, and the appended claims.
Referring to
According to the preferred embodiment, the foldable mattress comprises an inflatable supporting frame 10 for retaining a predetermined air therewithin and a reinforcing frame 20 supported on the inflatable supporting frame 10.
The reinforcing frame 20 comprises a plurality of reinforcing platforms 21 each having a top platform surface 211, wherein when the inflatable supporting frame 10 is deflated, the reinforcing platforms 21 are adapted to be overlappedly folded up to form a compact unit, as shown in
According to the preferred embodiment, the inflatable supporting frame 10 comprises a top layer 101, a bottom layer 102 overlappedly connected thereto and defining an air chamber 11 therebetween, and an air valve 12 communicating with the air chamber 11 for retaining the air therewithin in such a manner that the inflatable supporting frame 10 is adapted for being inflated through the air valve 12 for retaining a predetermined air pressure in the air chamber 11 and being deflated for releasing the air within the air chamber 11, as shown in
The inflatable supporting frame 10 is preferably made of material which is strong, flexible, elastic yet air-impermeable. The inflatable supporting frame 10 should be not only durable to provide secure support to the baby but also flexible to facilitate folding and unfolding for the foldable mattress when the inflatable supporting frame 10 is deflated. Thus, the inflatable supporting frame 10 should be air-impermeable so that the air, once inflated into the air chamber 11 through the air valve 12, will not be leaked until the inflatable supporting frame 10 is intentionally deflated through the air valve 12. And the inflatable supporting frame 10 should be elastic to allow the inflation and deflation thereof. Accordingly, the inflatable supporting frame 10 is preferably made of plastic or leather having a predetermined elasticity in order to fulfill the above objects.
As shown in
In order to form the resting surface 201 on the inflatable supporting frame 10 to support the weight of the baby, each of the reinforcing platforms 21 is preferably made of rigid but flexible material such as plastic or bamboo so as to provide an optimum level of hardness for the baby to lie on the foldable mattress. Customarily, a cushion layer is overlapped on the resting surface 201 of the foldable mattress to provide a soft and comfort feeling for the baby to lie thereon.
As shown in
It is worth to mention that when the inflatable supporting frame 10 is inflated, the air pressure retained within the air chamber 11 applies a stretching tension exerting on the reinforcing frame 20 to reinforce the alignment of each of the reinforcing platforms 21, so as to prevent the reinforcing platforms 21 from being folded up accidentally. Once the inflatable supporting frame 10 is deflated, the stretching tension is released such that the reinforcing platforms 21 are capable of being folded up, as shown in
In order to set up the foldable mattress of the present invention, the user, such as parents, is able to inflate the inflatable supporting frame 10 via the air valve 12 to retain a predetermined air within the air chamber 11. Once the inflatable supporting frame 10 is inflated, the reinforcing platforms 21 automatically form the resting surface 201 thereon. Accordingly, when the baby supports on the foldable mattress, the inflatable supporting frame 10 functions as an air cushion that automatically self-adjusts to deform corresponding to the weight of the baby. It is worth to mention that the user is able to adjust the softness of the foldable mattress by adjusting the amount of air within the air chamber 11. In other words, the foldable mattress becomes harder to support a heavy baby by inflating more air inside the air chamber 11. In medical sense, the air cushion as a supporting medium can prevent the foldable mattress becoming too hard so as to damage the backbone/body of the baby. Conversely, the air cushion can also prevent the foldable mattress becoming too soft so as to make the body of the baby being maintained in an unhealthy position on the bed.
When the parent needs to transport or store the foldable mattress, he/she can simply release the air within the air chamber 11 through the air valve 12 so as to deflate the inflatable supporting frame 10. After that, the reinforcing platforms 21 are adapted to be overlappedly folded to form a compact structure for transportation or storage purpose, as shown in
As shown in
To summarize, the foldable mattress disclosed above utilizes air as a supporting medium to provide body support to, for example, a baby. Since air is light in nature, plus the inflatable supporting frame 10 is foldable upon deflation, the present invention carries the maximum convenience for the user/buyer in transporting and storing. Moreover, the present invention provides the maximum flexibility to its user/buyer as to the usage.
One skilled in the art will understand that the embodiment of the present invention as shown in the drawings and described above is exemplary only and not intended to be limiting.
It will thus be seen that the objects of the present invention have been fully and effectively accomplished. It embodiments have been shown and described for the purposes of illustrating the functional and structural principles of the present invention and is subject to change without departure from such principles. Therefore, this invention includes all modifications encompassed within the spirit and scope of the following claims.
