Covers for mattresses and futons

Abstract

To provide a cover for futons that allows for easy insertion and removal of the futon. [Solution] A cover for bedding is formed in a bag shape using a surface fabric 1 and a backing fabric 2, and the four sides connecting the surface fabric 1 and the backing fabric 2 consist of short sides 3 and 4 and long sides 5 and 6. A zipper 10 is attached to three of these sides (for example, one long side 6 and the two short sides 3 and 4 connected to this long side 6). When the zipper 10 is opened, almost the entire surface fabric 1 can be opened, making it easy to put in and take out bedding or mattresses from the cover.

Description

Technical Field

[0001] This invention relates to a cover for bedding.

Background Art

[0002] In this specification, bedding includes the concepts of futons and mattresses. A cover for bedding is a square cover that is sewn into a bag shape so that a futon or a mattress can be put in entirely to protect it from dirt.

[0003] There is Patent Document 1 etc. in the prior art of covers for quilts, but there is no patent document showing the prior art of covers for bedding. Quilts are light, so a quilt can be easily put into and taken out of a cover with a light force. However, since futons and mattresses are heavy, it takes a considerable amount of force to take them out of or put them into a cover. Especially when taking out and putting in multiple futons or mattresses, the labor becomes very large and it is difficult to use at home. Therefore, even if a cover for a quilt is directly applied to a futon cover, it will not be a cover with good usability.

[0004] Conventionally used futon covers have been made by sewing a thin cloth surface cloth 101 and a back cloth 102 into a bag shape and attaching fasteners 110 to adjacent long sides and short sides, as shown in FIG. 7. Since the attachment position of the fastener 110 is L-shaped when viewed from above, as shown in FIG. 8, when the fastener is opened and the surface cloth 101 is opened, an area approximately half of the back cloth 102 is opened. However, the opened shape is triangular. In conventional futons, there is a problem that it is difficult to take out and put in a heavy futon because the opening is small even when the fastener 110 is opened. In recent years, there are also mattresses in the shape of futons, and the same problem occurs with these as well.

[Modes for carrying out the invention]

[0010] Next, embodiments of the present invention will be described based on the drawings. Below, we will first explain the covers that apply to mattresses.

[0011] (First Embodiment) A mattress cover A according to the first embodiment of the present invention will be described with reference to Figure 1. The futon cover A is a cover formed in a bag shape using a surface fabric 1 and a backing fabric 2 (which is on the back of surface fabric 1 and not visible in Figure 1). Gussets are formed on all four sides where surface fabric 1 and backing fabric 2 connect. Covers without gussets are also included in this invention. Both the surface fabric 1 and the back fabric 2 are rectangular, and the ratio of the lengths of the short sides 3 and 4 to the long sides 5 and 6 can be those of a well-known futon mattress, and there are no particular restrictions.

[0012] The futon cover A of this embodiment has four sides, consisting of short sides 3 and 4 and long sides 5 and 6, and zippers 10 are attached to three of these sides. In the futon cover A of FIG. 1, the fastener 10 is attached to one long side 6 and two short sides 3 and 4 connected to both ends of this long side 6. Therefore, there is no fastener 10 on the long side 5, and the surface cloth 1 and the back cloth 2 are connected. In FIG. 1, the fastener 10 is shown in a simplified manner.

[0013] The fastener referred to in this specification is a fastener that opens and closes a cloth tape with implanted serrated teeth by a slider as defined in JIS standard L0122. In the partial enlarged view in FIG. 1, it is shown that the fastener 10 is composed of three members: a cloth tape 11, serrated teeth 12, and a slider 13. Also, the serrated teeth 12 are composed of two serrated teeth 12a and 12b. Such a structure of the fastener 10 is well-known.

[0014] One slider 13 may be used to open and close the fastener 10, or two sliders 13 may be used. In the case of one slider 13 for the fastener, the slider 13 is pulled around from one end to the other end of the fastener 10 to open and close the cover. In the case of two sliders 13 for the fastener, the slider 13 is pulled around from near the center of the fastener 10 toward both ends to open and close the cover.

[0015] In the futon cover A of FIG. 1, when three sides are opened by the fastener 10, as shown in FIG. 2, almost the entire surface of the surface cloth 1 is opened. That is, since the surface cloth 1 includes one long side 6 and both short sides 3 and 4 are opened, the opening area becomes large. For this reason, even for a heavy futon, it becomes easy to put it in and out of the cover.

[0016] (Second Embodiment) The futon cover B according to the second embodiment of the present invention will be described based on FIG. 3. In the futon cover A of the first embodiment, the fasteners 10 are provided up to the ends of both short sides 3 and 4, but the second embodiment leaves non-opening / closing portions 7 and 8 without providing the fasteners 10 on both short sides 3 and 4.

[0017] The ratio of the short side to the long side of the surface fabric 1 and the back fabric 2, the structure of the zipper 10, the number of sliders 13 attached, etc., are the same as in the first embodiment.

[0018] The non-opening portions 7 and 8 connected to the ends of the zipper 10 are preferably about 1 / 10 to 1 / 4 of the length of the short side or long side. If the non-opening sections 7 and 8 are within the above dimensions, the necessary opening area for inserting and removing the futon mattress can be secured. Therefore, even heavy futons can be easily put in and taken out of the cover.

[0019] (Third embodiment) A mattress cover C according to the third embodiment of the present invention will be explained with reference to Figure 4. The futon cover C consists of a surface fabric 1 and a backing fabric, and the length ratios of the short sides 3 and 4 and the long sides 5 and 6 are substantially the same as those of futon cover A shown in Figure 1. Similarly, zippers 10 are attached to three of the four sides of the fitted sheet cover C. However, the sides to which the zipper 10 is attached are the short side 3 and the two long sides 5 and 6 connected to both ends of it. Therefore, the short side 4 does not have the zipper 10, and the surface fabric 1 and the back fabric 2 are connected there.

[0020] Even with this type of futon cover C, opening three sides with the zipper 10 opens almost the entire surface fabric 1, as shown in Figure 5. In other words, the surface fabric 1 includes one short side 3 and both long sides 5 and 6 open, resulting in a large opening area. Therefore, even heavy futons can be easily put in and taken out of the cover.

[0021] (Fourth Embodiment) A futon cover D according to the fourth embodiment of the present invention will be explained with reference to Figure 6. In the third embodiment of the futon cover C, the zipper 10 is provided to the ends of both short sides 3 and 4, but in the fourth embodiment, the zipper 10 is not provided on both short sides 3 and 4, leaving non-opening and closing sections 7 and 8.

[0022] The ratio of the short side to the long side of the surface fabric 1 and the back fabric 2, the structure of the zipper 10, the number of sliders 13 attached, etc., are the same as in the first embodiment.

[0023] These non-opening portions 7 and 8 are preferably about 1 / 10 to 1 / 4 of the length of the short side or long side. If the non-opening sections 7 and 8 are within the above dimensions, the necessary opening area for inserting and removing the futon mattress can be secured. Therefore, even heavy futons can be easily put in and taken out of the cover.

[0024] (Other embodiments) Although embodiments 1 to 4 described above are applied to futons, the cover of this invention can also be applied to mattresses in the same four embodiments. In particular, the cover of this invention is suitable for mattresses with a thickness similar to that of a futon. Furthermore, even heavy mattresses can be easily put in and taken out of the cover.
