1. Field of the Invention
The present invention relates to a mattress, and more particularly to a self-enclosable inflatable mattress having a bag formed on a body for folding therein.
2. Description of the Prior Art
Inflatable mattresses are designed to be compressible and portable for traveling and camping. Since the inflatable mattresses are easy to store without occupying too much space, they are also popular in families that do not have a guestroom for receiving visitors.
With reference to
However, since the single fastener (80) is attached in one place to the mattress body (90), the mattress body (90) might loosen and unroll, especially when carried, removed from a tight storage place or dropped, causing the mattress body (90) to require refolding and rolling, dirtying a surface of the mattress body (90) or maybe puncturing or tearing the mattress body (90), especially if dropped outside, and inconveniencing transportation, storage and use. Furthermore, during transport and storage the surface of the mattress body (90) may be covered by dust or dirt thus requires cleaning prior to use, especially inconvenient when camping.
A conventional inflatable mattress was disclosed in U.S. Pat. No. 7,401,370 B2. The inflatable mattress has a mattress body and a sleeve. The sleeve may be a flat fabric material, is attached to the mattress body, is extended from the mattress body and has two cinch mechanism. The cinch mechanism is formed on and extended along a side of the sleeve, selectively ties and tightens the sleeve around the mattress body and has a channel and a drawstring or a cord. The channel is formed through the cinch mechanism. The drawstring is mounted through the channel and selectively ties and tightens the sleeve around the mattress body. A similar conventional inflatable mattress was also disclosed in US publication NO. 2006/0037144 A1.
Although the mattress body can be covered by the sleeve, a part of the mattress body is still exposed to the air. Further, to use the drawstrings or cords of the cinch mechanism to tie and tighten the sleeve around the mattress body is relatively inconvenient. Moreover, the sleeve is limited to be made of flat fabric material, especially those with more flexibility for compactly wrapping the mattress body.
To overcome the shortcomings, the present invention provides a self-enclosable inflatable mattress to mitigate or obviate the aforementioned problems.
The main objective of the invention is to provide a self-enclosable inflatable mattress having a mattress body and an bag mounted on a surface of the mattress body, so that the mattress body can be easily stored in the bag, which is selectively flattened or accommodates the mattress body.
The self-enclosable inflatable mattress in accordance with the present invention comprises a mattress body and a bag.
The mattress body has a sidewall and a chamber. The chamber is defined in the mattress body.
The bag is connected to the mattress body and has a surrounding sheet, at least one holding sheet and at least one fastener. The surrounding sheet has a margin. The margin has at least one attaching segment. The at least one holding sheet is attached to the surrounding sheet and has a periphery. The periphery has an attaching section. The attaching section of the holding sheet is detachably connected to the corresponding attaching segment of the surrounding sheet, when the mattress body is encompassed by in the bag and when the bag is in an enclosed configuration. The at least one fastener is mounted between the attaching segment of the surrounding sheet and the attaching section of each holding sheet.
Thus, during transport and storage the surface of the mattress body may be covered by the bag without requiring further cleaning prior to use. Further, since the bag around the mattress body is not fastened by cinch mechanisms, the bag is not limited to be made of flexible material but can also be made of more rigid material such as canvas.
Other objectives, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
With reference to
The mattress body (10) may be rectangular, may be a resilient material and has a top (11), a bottom (12), a sidewall (13) and a chamber. The chamber is defined in the mattress body (10).
Multiple partitions are formed in the chamber between the top (11) and bottom (12) to retain a shape and may be aligned to facilitate folding and rolling.
The valve (30) is mounted through the mattress body (10), may be mounted through the sidewall (13) of the mattress body (10), protrudes into the chamber and selectively allows air to flow through the valve (30) to and from the mattress body (10).
The bag (20) is attached to the bottom (12) of the mattress body by sewing, adhering or welding and has a surrounding sheet (21), at least one holding sheet (22), at least one fastener (23) and optional at least one strap (24).
The surrounding sheet (21) may be rectangular, is connected to the mattress body (10) and has a margin (2101), and an optional attaching surface (211). The margin (2101) has at least one attaching segment. The attaching segment of the surrounding sheet (21) has a length. The attaching surface (211) of the surrounding sheet (21) is attached to the mattress body (10) and may be rectangular. The surrounding sheet (21) may be connected to the bottom (12) of the mattress body (10).
The at least one holding sheet (22), may be elliptical, has multiple optional breathing holes and is connected to the surrounding sheet (21), optionally aside the attaching surface (211) of the surrounding sheet (21) and has an periphery (2201) and an outer surface. Preferably two holding sheets (22) are implemented. The periphery (2201) has an attaching section and an optional fixing portion. The attaching section of the periphery (2201) of the holding sheet (22) may have a length equivalent to the length of the corresponding attaching segment of the margin (2101) of the surrounding sheet (21). The outer surface of the at least one holding sheet (22) is opposite to the attaching surface (211) of the surrounding sheet (21). The fixing portion of each holding sheet (22) is connected to a corresponding margin (2101) of the surrounding sheet (21).
The at least one fastener (23) may be a zip, a hook and loop fastener, strap, clip or the like and is mounted between the attaching segment of the margin (2101) of the surrounding sheet (21) and the attaching section of the periphery (2201) of the corresponding holding sheet (22) when the mattress body (10) is encompassed by the bag (20) and when the bag (20) is in an enclosed configuration. The strap (24) may be attached to the holding sheet (22) by sewing, adhering or welding and has two ends. The ends of each strap (24) may be respectively attached to the outer surface of the two holding sheets (22) or to the surrounding sheet (21) of the bag (20).
The air pump assembly (40) is mounted through the sidewall (13) of the mattress body (10), protrudes into the chamber inside the mattress body (10) and selectively inflates or deflates the mattress body (10).
