Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a sleeping bag (shulafzatsk) used for mountain climbing, camping, etc.

Conventional technology Sleeping bags used for mountain climbing, camping, etc. are sewn with outer and inner fabrics, and waterfowl feathers and synthetic cotton are used as insulation material inside.

However, when sleeping bags are used for mountain climbing, camping, etc., it is common to take off only the shoes and enter the sleeping bag with clothes on, which has the disadvantage that the toes of the feet tend to cool down and interfere with sound sleep. .

Problems to be Solved by the Present Invention This can be improved considerably by increasing the amount of heat insulating material or making the sleeping bag body double, but in this case, the volume increases and becomes bulky, making it inconvenient to carry and expensive. There are problems such as high prices.

The present invention improves the heat retention of the toes without increasing the amount of heat insulating material or making the sleeping bag body double, thereby improving the shortcomings of conventional products.

Means for Solving the Problems The present invention provides a short and small inner bag formed separately at the bottom of the sleeping bag body, and a belt that forms a desired space between the inner bottom of the sleeping bag body and the inner bag. The sleeping bag is stretched to maintain a space so that the toes do not come into direct contact with the bottom of the sleeping bag body, and the air that fills the space increases the heat retention of the toes.

Function: When the sleeping bag body of the present invention is extended to the use state, the inner bag is pulled to the bottom of the sleeping bag body by the tensioned belt, forming a space between the sleeping bag body and the inner bag,
The air in the space reduces heat conduction and improves the heat retention effect on the toes.

An example of its implementation will be described based on the drawings.

Embodiment In the present invention, feathers, synthetic fiber cotton, or a heat insulating material 6 having the same effectiveness as these is filled between the outer fabric 2 and the lining fabric 3, and quilting 8 is carried out, and optional opening/closing devices (fasteners, etc.) C are provided in desired areas. are provided to form the sleeping bag main body 1.

Next, a short and small inner bag A is formed by filling the insulation material 6 between the outer fabric 4 and the inner fabric 5 and quilting the main parts, and the bottom of this inner bag A is connected to the inner bottom B of the sleeping bag body 1. The upper end of the inner bag A is sewn 1 to the sleeping bag body 1.
It is a sleeping bag made of 0.

Note that the belt 9 is preferably made of a material that can be bent and expanded.

Since the present invention is constructed as described above, the method of use is the same as that of the conventional product: extend the sleeping bag body 1 to the use state, open the opening/closing device C, insert your body into the sleeping bag body 1, and close the opening/closing device C.

However, the toes are located in the inner bag A provided at the inner bottom of the sleeping bag body 1. Since the bottom of the inner bag A is stretched with a belt 9 so as to create a space 7 between it and the inner bottom B of the sleeping bag body 1, the toes of the feet do not come into direct contact with the bottom B of the sleeping bag body 1. Moreover, as a result of the air filling the space 7 reducing heat conduction from inside and outside,
Cooling of the toes is significantly reduced, providing excellent heat retention.

In particular, since the bottom of the inner bag A is stretched with a belt 9 so as to create a space 7 between it and the bottom B of the sleeping bag body 1, when you place your toes on the inner bag A, the weight of the inner bag causes your heel to move. The inner bag of the part is depressed and the space 7 is reduced,
Since a sufficient space 7 can be secured between the soles of the feet and the fingertips, an excellent heat retention effect can be maintained. In addition, since the inner bag A is short and small and is located near the bottom B of the sleeping bag body 1, it does not take up much bulk when folded and carried. Thus, a sleeping bag useful for mountain climbing, camping, etc. can be provided.
