DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mattress sheet provided on a bed mattress.

[0002]

2. Description of the Related Art Generally, a bed is provided with a mattress, and the mattress is covered with sheets. As a mattress sheet, a rectangular cloth which is sufficiently larger than the mattress is used, and a peripheral portion of the cloth is folded into the lower surface side of the mattress during bed making.

[0003] However, simply folding the periphery of the sheet into the lower surface of the mattress in this way not only causes the folded state to be released during use and causes the sheet to be rounded, but also has a margin for folding the sheet. Since the size of the mattress had to be increased, a large cloth was required as compared with the size of the mattress.

Therefore, a bag is formed over the entire length of the peripheral edge of the rectangular cloth, and a rubber string is passed through the bag to elastically shrink the peripheral edge of the cloth to form a sheet. Are used so that the periphery of the mattress is engaged with the lower surface of the mattress.

According to such a sheet, since the peripheral portion is elastically engaged with the lower surface of the mattress, it is possible to prevent the peripheral portion of the sheet from coming off the mattress and curling with use. Further, the fabric can be made smaller than when the peripheral edge is folded.

[0006] However, according to such sheets, when removed from the mattress, the rubber strap is provided on the peripheral edge and the sheet is shrunk. It was difficult to iron, and it was difficult to iron after drying, and furthermore, it was difficult to fold properly after ironing.

[0007]

As described above, the conventional mattress sheets are elastically contracted by providing a rubber string around the periphery so that the sheets are hard to come off from the mattress. However, since it shrinks when it is removed from the mattress, it may be difficult to dry even after washing and drying, it may be difficult to iron, or it may not be able to be folded properly.

An object of the present invention is to provide a mattress sheet that can be elastically provided on a mattress by a rubber string and that is not shrunk by the rubber cord when detached from the mattress. .

[0009]

According to a first aspect of the present invention, there is provided a sheet for covering an upper surface and a side surface of a mattress, wherein a rectangular sheet main body, concave portions formed at four corners of the sheet main body, A pair of bags each formed along the side edge in a state where the recesses are sandwiched between the side edges, a rubber cord and a hook rotatably provided at both ends of the rubber cord, A connector for passing the rubber cord through a pair of bags sandwiching the recess and rotating the hook to engage the bag to elastically contract the corners of the sheet body with the rubber cord. It is characterized by having.

According to a second aspect of the present invention, in the first aspect of the present invention, the rubber string is a flat rubber, and the hook has a slit for connecting the flat rubber and a large hole formed at least at one end of the slit. A diameter portion is formed.

According to the first aspect of the present invention, the connecting device provided with the rubber cord through the bag formed at the corner of the sheet main body rotates the hook to release the engagement with the bag. Since it can be removed from the main body, it is possible to remove the contracted state of the corner of the sheet main body due to the rubber string.

According to a second aspect of the present invention, when the hook is rotated in the same direction as the longitudinal direction of the flat rubber and the flat rubber is passed through or removed from the bag, the hook is connected to the flat rubber hook. Since the hook and the flat rubber can be made linear by the large diameter portion formed at the end of the slit, the rubber string can be easily inserted and removed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 3 shows a bed 1, which is provided with a bed frame 3 having a headboard 2 erected at one longitudinal end. A mattress 4 is placed on the bed frame 3, and the mattress 4 is covered with a sheet 5.

As shown in FIG. 4, the sheet 5 has a sheet body 6 made of a cloth formed in a substantially rectangular shape. At the four corners of the sheet body 6 are formed rectangular recesses 7 each having a corner removed at a right angle.

At the four side edges of the sheet body 6, a bag portion 9 is formed over the entire length in the longitudinal direction of the corner edge by bending its end to the inner surface side and sewing it with a seam 8. The bag 9 at each side edge has the recess 7 at both ends.
A cut line 11 is provided at a portion inside the recess 7 by a predetermined dimension to open the bag portion 9 at that portion.

A connecting member 13 is provided at each of the four corners of the sheet body 6. This connecting member 13 is shown in FIG.
As shown in FIG. Hooks 15 are connected to both ends of the flat rubber 14. That is, the hook 15 is made of a relatively hard synthetic resin or the like, and is formed of a band-shaped member having a width smaller than the width of the bag portion 9, and the hook 15 has a slit 16 formed over substantially the entire length in the longitudinal direction. One end of the slit 16 has a large-diameter portion 17 having a diameter larger than the width of the slit 16.
Are formed. The inner diameter of the large diameter portion 17 is desirably substantially the same as or slightly larger than the width of the flat rubber 14.

The flat rubber 14 has both ends inserted into the slit 16 and is bent, and the overlapped portion is sewn. Thereby, the hooks 15 are rotatably connected to both ends of the flat rubber 14, respectively.

The connecting member 13 rotates one hook 15 so as to be aligned with the flat rubber 14, and the hook 1
The bag 5 is inserted into the bag body 9 from the cut line 11 formed on one side edge of the sheet body 6 and is drawn out from the end of the bag body 9 opened to the concave portion 7. This is indicated by arrow A in FIG.

Next, the hook 15 is inserted from the opening end of the bag 9 formed on the side edge adjacent to the one side edge of the sheet body 6, and the flat rubber 14 is extended while the bag 9 is being extended.
From the cutting line 11. This is indicated by arrow B in FIG. Next, the hook 15 is rotated substantially perpendicularly to the longitudinal direction of the flat rubber 14.

Thus, as shown in FIG. 1, a pair of hooks 15 provided at both ends of the flat rubber 14 are engaged with the cut lines 11 of the pair of bag portions 9 sandwiching the concave portion 7 of the sheet body 6. As a result, the corners of the sheet body 6 are contracted by the elasticity of the flat rubber 14 and both ends sandwiching the recess 7 are pulled to form a box corresponding to the shape of the mattress 4. Deform.

Therefore, the mattress 4 is
By covering the upper surface and the outer peripheral surface of the mattress 4, the peripheral portion thereof can be engaged with the lower surface of the mattress 4 by the elasticity of the flat rubber 14, so that the sheet body 6 comes off from the mattress 4 during use. It can be provided without.

When the sheet body 6 is to be washed, if it is detached from the mattress 4, the connecting members 13 provided at the four corners thereof are detached. That is, one hook 15 provided on the flat rubber 14 is rotated so as to be in line with the flat rubber 14, and inserted into the bag 9 on one side edge from the cutting line 11,
Pull out from the bag 9. Similarly, the other hook 15 is rotated so as to be aligned with the flat rubber 14, inserted into the other bag portion 9 from the cutting line 11, and taken out from the bag portion 9.

As a result, the contracted state of the corners of the sheet body 6 due to the flat rubber 14 is removed, so that it does not curl up when washing and drying, so that it is easy to dry and easy to iron after drying. , And can be folded more neatly. Moreover, since the sheet body 6 can be washed by removing the connector 13, it is possible to prevent the connector 13 from being damaged early.

When the flat rubber 14 is passed through the bag section 9 or withdrawn from the bag section 9, the hook 15 is rotated so that the large rubber section 17 formed in the slit 16 forms the flat rubber 14.
Can be positioned without greatly curving.

As a result, the hook 15 and the flat rubber 14 can be aligned as shown in FIG. That is, it is possible to prevent the end of the flat rubber 14 from protruding to the side of the hook 15. Therefore, when the flat rubber 14 is inserted into or removed from the bag portion 9,
The work can be performed smoothly because the work is not easily caught.

Further, since the concave portion 7 is formed at the corner of the sheet body 6, when the connecting member 13 is provided at the corner, the corner of the sheet body 6 is formed by the elasticity of the flat rubber 14 of the connecting member 13. Since the part is contracted, it can be deformed into a box shape corresponding to the shape of the mattress 4, so that the sheet main body 6 can be fitted to the mattress 6 according to the shape of the mattress 4. That is, the sheet body 6 can be favorably provided on the mattress 6 without causing large slack or the like.

The present invention is not limited to the above embodiment, but can be variously modified. For example, the bag portion formed on the sheet body may not be formed over the entire length of the side edge portion, but may be formed with a predetermined length across the concave portion. Further, the hook may be formed with a large diameter portion at both ends as well as at one end.

[0029]

According to the first aspect of the present invention, the connector provided at the corner of the sheet main body by passing the rubber string through the bag section rotates the hook connected to the rubber string to connect with the bag section. Because you can remove it from the sheet body by releasing the engagement,
This makes it possible to remove the contracted state of the corner of the sheet main body due to the rubber string.

For this reason, when the washed sheet body is hung, its corners are not rounded and difficult to dry.
It is also easy to iron and can be folded properly. Further, since the connector can be removed and washed, the connector is less likely to be damaged. The invention according to claim 2 is that the hook is rotated in the same direction as the longitudinal direction of the flat rubber to pass the flat rubber through the bag portion. When the flat rubber and the hook are removed from the bag portion, the flat rubber and the hook can be straightened by locating the portion connected to the flat rubber hook at the large diameter portion formed at the end of the slit. That is, it is possible to prevent the end of the flat rubber from protruding to the side of the hook.

Therefore, when the rubber cord is passed through the bag, it is possible to prevent the end of the rubber cord from being caught in the bag, so that the rubber cord can be easily inserted into or removed from the bag. be able to.
