Description

CROSS REFERENCE TO RELATED APPLICATION

This application claims priority to Chinese Patent Application Number 201710265608.0, filed Apr. 21, 2017, which is hereby incorporated by reference.

TECHNICAL FIELD

The present invention relates to a sleeping bag, and particularly relates to a multifunctional sleeping bag with insertable and composable parts and a combined sleeping bag.

BACKGROUND OF THE INVENTION

With the development of the society and the improvement of people's living standard, many people show an increasing passion for outdoor sports, and the demand for outdoor products is thus increasing. As one kind of essential equipment for outdoor camping while traveling, sleeping bags function to keep people warm when they are sleeping during a camping trip.

Chinese Patent CN204120683U, incorporated herein by reference, has disclosed a split-type sleeping bag, including cotton-padded clothing and a leg warm-keeping bag arranged at the lower portion of the cotton-padded clothing, wherein matched connecting devices are arranged at openings of the cotton-padded clothing and of the leg warm-keeping bag. The sleeping bag is simple in structure, and the cotton-padded clothing can be independently put on to resist cold. When the cotton-padded clothing and the leg warm-keeping bag are connected by the connecting devices, the whole piece can serve as a sleeping bag. However, this sleeping bag has no pillow, and poor sleep quality will be caused during a camping trip due to the lack of a pillow. If a pillow is additionally carried along during the camping trip, an unnecessary burden will be caused, and it is very inconvenient.

Chinese Patent CN204500151U, incorporated herein by reference, has disclosed a sleeping bag, including a sleeping bag body, wherein a sleeping bag cap and a warm-keeping strip are sewed on an upper bottom edge of the sleeping bag body, and a wind shielding strip is sewed on an edge of the sleeping bag cap. An intermediate layer is sewed within the sleeping bag body, and a warm-keeping pad is placed inside the intermediate layer. The warm-keeping pad inside the intermediate layer of the sleeping bag may be separated and taken out, so that the sleeping bag is suitable for different seasons. Elastic tapes on the sleeping bag body are used for fixing the sleeping bag when the sleeping bag is folded up. A pillow is provided within an intermediate bag, so that it is more conformable when a person lies in the sleeping bag. During a camping trip, users always want to carry fewer articles with small size and light weight as far as possible, but the sleeping bag has accessories such as the pillow, the warm-keeping strip, the wind shielding strip and the warm-keeping pad, so that the sleeping bag has a large size and a heavy weight, and is inconvenient to carry.

During an outdoor adventure in a cold place, people often put on thick clothing such as jackets, down jackets, coats and so on. When a person goes to sleep or takes a rest in a sleeping bag at night, the coat is usually taken off and put aside, or folded up to serve as a pillow. However, this coat is merely used as a pillow and unable to play its warm-keeping role; or, the coat is covered on the sleeping bag to achieve the thickening and warm-keeping effects, but the coat will be slipped off when the person turns over while sleeping, so that the thickening and warm-keeping effects are not really achieved. Moreover, many sleeping bags are not provided with a pillow, and even if the coat is covered on the sleeping bag for keeping warm, the problem of poor sleep quality caused by the lack of a pillow remains unsolved. Hence, the coat is not fully utilized in case of being short of outdoor resources.

As described above, in the prior art, the sleeping bags necessary for an outdoor trip, the clothing worn, and other warm-keeping articles (e.g., scarves and so on) carried are generally independent from each other, or may be used only in a simple combination, for example, the coat is folded to serve as a pillow. Thus, the inventor considers that the function of a sleeping bag is not fully utilized, and it is necessary to design a novel sleeping bag which makes full use of the carried clothing and warm-keeping articles in a trip and is convenient to carry and easy to use.
