Description

  The present invention relates to a rectangler type sleeping bag, and more particularly to a rectangler type sleeping bag that can be used in a state where it is unfolded and connected in two layers.

  There are two types of sleeping bags: a rectanglar sleeping bag and a mummy sleeping bag. The cloth material of any sleeping bag is formed by putting a cotton pad between the outer material and the lining material cut into respective shapes and sewing them together. The Mommy sleeping bag has a head side hole and one or two sets of slide fasteners extending from the hole to the foot side so that the user can enter from the foot and put out the head and face. The legs are sewn together in a thin bag shape. On the other hand, the rectangler-type sleeping bag is formed in a rectangular shape with the cloth material formed in a rectangular shape and one end (head side end portion) is opened in a folded state. A set of slide fasteners is provided in the vicinity of the three sides to the both sides.

  The length of the rectanglar sleeping bag from the opening end to the foot end is about 190 cm and the opening width is about 84 cm as a standard (regular size). However, in some cases, the length from the opening end to the foot end is about 200 cm and the opening width is about 100 cm according to the physique of the user (king size).

  For example, when a person with a small physique enters a king-sized rectangler-type sleeping bag, there is a problem that an extra gap is formed in the entire body, the inside is difficult to warm, and warm air easily escapes. On the other hand, since the thickness of the clothing when entering the sleeping bag differs depending on the season, there are cases where a regular size sleeping bag is usually sufficient for a person who needs a king size sleeping bag. Therefore, in order to eliminate the unreasonableness of having to equip two types of rectangler type sleeping bags, there is a need for a rectangler type sleeping bag that can be transformed into a regular size and a king size.

  In recent years, there have been many occasions where it is used in large tents and in cars of sufficient size, such as in auto camps, so two rectanglar sleeping bags can be used simultaneously by multiple people. May be used by connecting the rectangler type sleeping bag by connecting the slide fasteners in an open state with the linings facing each other. Structurally, such a connection cannot be made with a Mummy type sleeping bag, but such a connection can be made with a Rectangler type sleeping bag by sharing the size and the type of slide fastener.

  Japanese Patent No. 2574633 describes a rectangler type sleeping bag with an improved connection function.

  However, since the size of the rectangler type sleeping bag of different sizes is different in both the size of the cloth material itself and the length of the slide fastener, it is difficult to connect the two. Therefore, there is a problem that even if regular size sleeping bags and king size rectangular sleeping bags can be connected to each other, different size rectangular sleeping bags cannot be connected to each other.

  Therefore, if you already own a rectangle sleeping bag and purchase a connecting rectangle sleeping bag, it is necessary to match the size of your sleeping bag. For example, regular size and king size 2 Even if you purchase a type, you cannot make such a connection. On the other hand, if you have the same size, even if you have two sleeping bags, there is a problem that you can not change the size according to the situation .

Japanese Patent No. 2574633

  An object of the present invention is to provide a rectangular-shaped sleeping bag that can be deformed into both a regular size and a king size and that can be connected with sleeping bags having a common size.

  The rectangler type sleeping bag of the present invention is a rectangler type sleeping bag in which one end is opened when a rectangular fabric is folded in two by a first connecting means and a second connecting means that can be connected. A gusset is provided on a side where the means is provided, and a third connecting means and a fourth connecting means capable of being connected are provided on the outer side of the gusset and the side where the second connecting means is provided. Normally, the opening width can be expanded by expanding the gusset outward from the side where the first connecting means is located and connecting the third connecting means and the fourth connecting means.

  Further, it is preferable that each connecting means is a slide fastener.

  Furthermore, it is possible to connect the first connecting means and the second connecting means with each other by overlapping the two rectanglar sleeping bags in an opened state with the lining facing each other, and It is preferable that the third connecting means and the fourth connecting means can be connected.

  The present invention provides a rectangular sleeping bag that can be transformed into both a regular size and a king size and can be connected to each other as long as the sleeping bag is the same size. It became possible to meet.

  The present invention will be described with reference to the drawings. FIG. 1 is a plan view showing a rectangular sleeping bag according to an embodiment of the present invention. 2 is a plan view showing a use state in a regular size, and FIG. 3 is a cross-sectional view taken along the line III-III in FIG. 4 is a plan view showing a use state in a king size, and FIG. 5 is a cross-sectional view taken along line VV in FIG.

  The cloth material has a rectangular shape, and accommodates batting that provides a heat insulating effect by the outer material (11) and the lining material (12). With the first slide fastener (14) and the second slide fastener (15) that can be connected to each other (both constitute a pair of slide fasteners), the cloth material has an opening width of a regular size in a folded state. It has a one-open open rectangle body. The slider (14a) may be provided on the first slide fastener (14) or on the second slide fastener (15). The connecting means may be any known technique such as a hook-and-loop fastener and a button stop, instead of a slide fastener.

  A gusset (13) made of a cloth material having a long side from the open end to the middle of one side is provided on the side of the main body where the first slide fastener (14) is located.

  Further, the third slide fastener (21) is provided on the outer side (the side not connected to the main body) of the gusset (13), and the fourth slide fastener (22) to be combined with the third slide fastener is provided. The second slide fastener (15) is provided in a portion corresponding to the installation position of the third slide fastener in the vicinity of the side of the main body. The slider (21a) may be provided on the third slide fastener (21) or on the fourth slide fastener (22). The fourth slide fastener (22) may be provided so as to be parallel to the second slide fastener (15), either on the outer surface (11) side or on the lining (12) side, Either is acceptable.

  As shown in FIG. 1, the gusset (13) has a shape in which two substantially triangles are symmetrically juxtaposed in the unfolded state. As shown in FIG. Form. In a normal use state, the entire body is folded, but the gusset (13) is pulled out from the body and folded to connect the third fastener and the fourth fastener. An extension is formed on the side.

  That is, by setting the width at the opening of the gusset (13) to about 32 cm and connecting the third slide fastener (21) and the fourth slide fastener (22), an opening width of 84 cm, which was a regular size, is obtained. It becomes expandable to 100cm of opening width which is king size.

  In the illustrated example, the gusset (13) has a substantially triangular shape, and the portion from the waist to the top swells in a trumpet shape so that the opening width becomes the king size. Even if a person has a large body shape, the difference from the waist to the bottom is small compared to a person with a general body shape, and usually the cross-sectional area from the waist to the chest is large. A trumpet shape with a wide end is sufficient. However, for example, the gusset (13) may be formed into a vertically long rectangle of about 32 cm × about 190 cm so as to be deformable into the shape of a normal king-sized rectangular bag. The gusset (13) may be fan-shaped.

  6 is a plan view showing a connected state of two rectanglar sleeping bags, and FIG. 7 is a sectional view taken along line VII-VII in FIG.

  Two rectanglar sleeping bags of the present invention are connected to the first slide fastener (14) of one sleeping bag and the second slide fastener (15) of the other sleeping bag, with the linings facing each other. By connecting in this way, two or more people can be used simultaneously.

  Further, in the case of the rectangle type of the present invention, by pulling out each gusset (13) and connecting one third slide fastener (21) to the other fourth slide fastener (22). The extended portions can be formed on both sides, and the length of the open end can be expanded to 200 cm. It can be used by adults of large size and all parents and children at the same time.

  In the illustrated embodiment, the two rectangular bags of the present invention are connected. However, it is also possible to connect the rectangular bag of the present invention to a conventional regular size rectangular bag. . In this case, the extended portion cannot be formed by the gusset (13). However, in the case of single use, the above-described operation and effect are provided, so that various situations can be dealt with.
