Inflatable mattress with a coverlet
An inflatable mattress has a body and a coverlet. The body is hollow, is inflatable and has a top, a sidewall and at least one first engaging member attached to the sidewall of the body. The coverlet is mounted detachably on and covers the body and has at least one second engaging member attached to the coverlet and corresponding respectively to and detachably engaged respectively with the at least one first engaging member on the body. The coverlet is mounted tightly on the body and would not be shifted by persons' movement on the inflatable mattress.
1. Field of the Invention
The present invention relates to a mattress, and more particularly to an inflatable mattress that has a body and a coverlet tightly and flatly mounted detachably on the body without any wrinkles so that the coverlet on the body looks tidy and would not be shifted inadvertently by persons' movement on the inflatable mattress.
2. Description of Related Art
Inflatable mattresses are used generally in travels and camping because of their compressibility and portability.
However, people lying on the inflatable mattress feel less comfortable than they feel when lying on a traditional bed because of no sufficient soft cushion such as cotton fill put in the inflatable mattress.
U.S. Pat. No. 7,007,329 disclosed a conventional inflatable mattress with a pillow top. The pillow top is mounted on a top of a mattress body. However, the pillow top has no cushion function so that people lying on the pillow top on the mattress body would still feel more uncomfortable as compared with conventional beds. Furthermore, the conventional inflatable mattress has a second fastener portion attached to the edge weld of the inflatable mattress. The attachment prevents the pillow top to be secured tightly to the surface of the inflatable mattress and would appear to be “loose” across the surface of the inflatable mattress.
To overcome the shortcomings, the present invention provides an inflatable mattress with a coverlet to mitigate or obviate the aforementioned problems.
SUMMARY OF THE INVENTIONThe main objective of the invention is to provide an inflatable mattress that has a body and a coverlet tightly and flatly mounted detachably on the body without any wrinkles so that the coverlet on the body looks tidy and would not be shifted inadvertently by persons' movement on the inflatable mattress.
An inflatable mattress in accordance with the present invention comprises a body and a coverlet. The body is hollow, is inflatable and has at least one first engaging member attached to the body. The coverlet is mounted detachably on and covers the body and has a top cushion and at least one second engaging member attached to the coverlet and corresponding respectively to and detachably engaged respectively with the at least one first engaging member on the body.
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 body (2) is hollow, is inflatable and has a top (21), a bottom (22), a sidewall (23) and at least one first engaging member.
The sidewall (23) is annular, may be rectangular and have four side surfaces and four corners.
The at least one first engaging member, is attached to the sidewall (23) of the body (2) at a distance from the top of the body (2) and is at least one hook (41) mounted on the sidewall (23). A preferred embodiment of the body (2) has four sets of at least one hook (41) mounted respectively on the four side surfaces of the sidewall (23).
The coverlet (1) is mounted detachably on and covers the body (2) and has a top cushion (11), a skirt (12) and at least one second engaging member.
The top cushion (11) is soft and resilient, is located above on the top of the body (2), corresponds to the top (21) of the body (2) and has an outer edge, an internal chamber and a fill. The internal chamber is defined in the top cushion (11). The fill is made of fiber such as cotton or wool and is filled in the internal chamber so that the cushion (11) may provide a soft and comfortable feel to persons lying on the coverlet (1).
The skirt (12) is annular, extends out from the outer edge of the top cushion (11), corresponds to the sidewall (23) of the body (2) and has an outer edge.
The at least one second engaging member is attached to the skirt (12) of the coverlet (1) and corresponds respectively to and is detachably engaged respectively with the at least one first engaging member. In some aspects, a distance from the at least one second engaging member to the outer edge of the top cushion (11) may be shorter than the distance from the at least one first engaging member to the top of the body (2) so that the coverlet (1) mounted on the body (2) is stretched tightly and flatly. The skirt (12) is pulled and the coverlet (1) is stretched tightly across the top (21) and the sidewall (23) of the body (2) when the at least one second engaging member is engaged respectively with the at least one first engaging member on the sidewall (23) of the body (2). Therefore, the coverlet (1) is mounted tightly and flatly to the body (2) without any wrinkles. The at least one second engaging member is at least one loop (42) mounted on the skirt (12), detachably mounted respectively around and hooked respectively by the at least one hook (41) on the sidewall (23) of the body (2) so that the coverlet (1) would be mounted detachably on the body (2). A preferred embodiment of the coverlet (1) has four sets of at least one loop (42) mounted on the skirt (12), corresponding respectively to the sets of the at least one hook (41). The at least one loop (42) of each set is mounted respectively around and hooked respectively by the at least one hook (41) of a corresponding set.

The engagement of the at least one first engaging member on the sidewall at the distance from the top (21) of the body (2) and the at least one second engaging member on the skirt (12) of the coverlet (1) keeps the coverlet (1) mounted tightly and flatly on the body (2) without any wrinkles. Therefore, the coverlet (1) on the body (2) looks tidy and would not be shifted or detached inadvertently by persons' movement on the inflatable mattress. Also, the coverlet (1) with the top cushion (11) provides a soft and comfortable feel to persons lying on the inflatable mattress so that they would easily relax to sleep. Furthermore, the coverlet (1) is detachably mounted on the body (2) so that can be individually washed and stored. Moreover, persons carrying the inflatable mattress for travel and camping may take or leave the coverlet (1) home depending on whether they wants a fine sleep or simple and light baggage.
Even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only. Changes may be made in the details, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
