BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing a pillow 10 and a pillow cover 12 put on the pillow 10.
The pillow 10 is a long pillow having a length L1 at least as large as the width of a person's shoulder. A recess 14 is provided in a central portion of the pillow on which the head rests in the length direction. In other words, bulges 16 and 18 are provided on both sides in the length direction with respect to the central portion.
[0013]
The pillow cover 12 that is put on the pillow 10 having the above-described shape has a bottomed cylindrical shape. The pillow cover 12 is completely covered in the direction of the arrow until one end in the length direction of the pillow 10 reaches the bottom. The overall length L2 of the pillow cover 12 is longer than the overall length L1 of the pillow 10 by L4. When the pillow cover 12 is completely covered by the pillow 10, the L4 portion is folded back, and further, the half that is outside at the time of the folding is turned over and attached to the pillow 10.
[0014]
FIG. 2 is a view of the pillow cover 12 as viewed from a side opposite to that shown in FIG. That is, FIG. 2 shows a portion of the pillow cover 12 that is on the bottom side of the pillow 10 (bed mounting surface side). A stop band (hereinafter, referred to as a “pillow-side stop band”) 20 which is a band-shaped member is attached to the outer peripheral surface of the pillow cover 12 on the bed placement side. The pillow-side stop band 20 has a width W2 and a length L5, and is attached in a direction in which the width direction matches the length direction of the pillow cover 12 (and the pillow 10).
[0015]
The pillow side stopper 20 has one end (a portion indicated by reference numeral 22) facing the length direction fixed to the pillow cover 12 by sewing or bonding. The other end is fixed by the planar fastener 24. That is, the hook-side member 26 of the sheet fastener is sewn (or stuck) to the other end, and the loop-side member 28 of the sheet fastener is stitched (or stuck) to the pillow cover 12 side. ), And are fixed by engaging both members.
[0016]
The loop-side member 28 is sewn (or stuck) at a position where both the pillow cover 12 and the pillow-side stopper band 20 do not loosen while being engaged with the hook-side member 26. That is, the length L6 and the length L7 shown in FIG. 2 are set to be substantially the same. This length L6 is the length of the non-fastened portion of the pillow-side stop band 20 in a state where the pillow-side stop band 20 is fastened to the pillow cover 12 by the planar fastener 24.
[0017]
In addition, the length L6 of the non-fastened portion substantially matches the width W1 of the pillow 10 (see FIG. 1). The pillow cover 12 is put on the pillow 10 so that the bottom of the pillow 10 comes to a portion corresponding to L6.
On the other hand, as shown in FIG. 3, the sheet 34 hung on the mat 32 of the nursing bed 30 is provided with a bed-side stop band 36 to be engaged with the pillow-side stop band 20. The nursing bed 30 has a configuration in which a mat 32 is provided between a headboard 38 and a footboard 40, and a so-called box-shaped sheet 34 is hung on the mat 32. The mat 32 is divided into three in the length direction (longitudinal direction) of the care bed 30 (the division is not shown). The mat 32 is supported by a mat displacement mechanism (not shown) that can be displaced for each of the divided mats, and can perform so-called back raising, knee raising, and height adjustment by the mat displacement mechanism. It has become. The mat displacement mechanism has a rolling function of tilting the entire mat 32 leftward or rightward of the care receiver to prevent the care receiver from rubbing the floor.
[0018]
The bed-side stopper band 36 is a band-shaped member having a length L8 and a width W3, and the length direction is provided in accordance with the width direction (transverse direction) of the bed. The bed-side stopper strip 36 has both ends facing in the bed transverse direction fastened (sewed) to the sheets 34 by sewing, and the length of the unfastened non-fastened portion is L9. I have. The length L9 of the non-fastened portion is set to substantially the same length as the width W2 of the pillow side stopper band 20. Further, the length L6 of the non-fastened portion of the pillow-side stop band 20 is set longer than the width W3 of the bed-side stop band 36.
[0019]
FIG. 4 shows a state in which the pillow 10 is locked on the bed 30, that is, a pillow cover 12 covered on the pillow 10 on a bed-side stopper band 36 fixed on a sheet 34 hung on a mat 32 of the bed 30. FIG. 6 is a view showing a state in which the pillow-side stopper band 20 fastened to the front side is engaged. For convenience of explanation, the pillow cover 12 is not shown in FIG. 4 and the pillow 10 is drawn by a two-dot chain line.
[0020]
First, the pillow cover 12 is attached (covered) to the pillow 10 as described above. Then, the pillow-side stopper band 20 is inserted into the gap between the bed-side stopper band 36 and the sheet 34. At this time, the pillow-side stopper band 20 is inserted so that the sewing portion 22 is on the headboard 38 side and the hook-side member 26 is on the footboard 40 side. After the insertion, the hook side member 26 and the loop side member 28 are engaged with each other to complete the mounting.
[0021]
Since the pillow 10 is attached to the bed 30 as described above, even if the bed 30 is rolled, the pillow 10 hardly shifts in the tilt direction. Since the width W2 of the pillow-side stop band 20 and the length L9 of the non-fixed portion of the bed-side stop band 36 are set to substantially the same length, the displacement of the pillow cover 12 and thus the pillow 10 in the cross-bed direction is limited. Because it is regulated. In other words, the width W2 of the pillow-side stop band 20 and the length L9 of the non-fixed portion of the bed-side stop band 36 are such that the pillow cover 12 and the pillow 10 restrict the displacement in the cross direction of the bed (almost). Because they are set to the same length). As a result, even if the muscular strength of the neck is reduced, it is possible to prevent the head from being shifted together with the pillow during rolling. Further, as described above, the pillow 10 has the concave portion 14 at the center and the bulging portions 16 and 18 on both sides thereof, so that the head is effectively held by the pillow 10, and In addition, the head pillow is prevented from shifting.
[0022]
On the other hand, when the bed 30 is raised as shown in FIG. 5 (in FIG. 5, the knee is slightly raised at the same time), even if the head is displaced relatively to the mat 32 (sheets 34). The pillow 10 can also move in accordance with the displacement of the head. Because the length L6 of the non-fixed portion of the pillow-side stop band 20 is set longer than the width W3 of the bed-side stop band 36, the pillow cover 12 and thus the pillow 10 can be displaced in the bed longitudinal direction. It is. As a result, the feeling of being dragged when the head is pulled by the pillow 10 (pillow cover 12) is reduced.
[0023]
The displacement amount of the pillow 10 (the pillow cover 12) allowed in the bed longitudinal direction (hereinafter, referred to as “permissible displacement amount”), that is, the width W3 of the bed-side stop band 36 and the non-fixation of the pillow-side stop band 20. The difference from the length L6 of the portion is set to 10 cm. The maximum back elevation angle α of the bed 30 is 70 °, but the relative displacement of the head with respect to the mat (sheets) generated when the back is raised by the maximum angle from a flat state is 7 to 8 cm. Was. Therefore, the actual measured value is set to 10 cm with a margin. Needless to say, the allowable displacement is not limited to 10 cm. In short, it is only necessary that at least the displacement amount at which the head is displaced relative to the mat (sheets) when the bed is raised is secured.
[0024]
When the back is raised, the head is displaced in the direction of the headboard 38 relatively to the mat (sheets). The bed-side stopper strip 36 is fixed to the sheet 34 at a position where the pillow 10 (pillow cover 12) can be displaced in accordance with the displacement of the head described above. That is, when the pillow is placed at a position where the head of the non-caregiver comes to the bed in a state where the mat surface of the bed is flat, as shown in FIG. On the other hand, the bed-side stopper band 36 is fixed at a position where the bed-side stopper band 36 is slid to the full side of the footboard.
[0025]
Then, as the bed is raised, the head is displaced toward the headboard with respect to the sheets (mat) as described above. Accordingly, the pillow 10 (pillow cover 12) is also moved by the arrow A. It will slide in the direction (direction toward the headboard).
At this time, since the length of the pillow 10 is at least about the width of the shoulder of the non-caregiver, the pillow 10 is pressed by the shoulder of the non-caregiver, and the pillow 10 slides more smoothly.
[0026]
Also, when raising the back, the non-caregiver raises the body more than the angle of raising the back, the head of the non-caregiver separates from the pillow 10, and the back of the non-caregiver separates from the sheets (mat). However, even in such a case, the pillow 10 only slides to the state shown in FIG. 6A and does not fall. The pillow-side stop band 20 is inserted through the bed-side stop band 36 such that the sewing portion 22 is on the headboard 38 side and the hook-side member 26 is on the footboard 40 side. This prevents the planar fastener 24 from coming off due to the impact at the time of the slide, which may occur when the slide fastener is inserted in the opposite direction.
[0027]
The pillow 10 (pillow cover 12) can be slid smoothly so that the fabric used for the pillow-side stop band 20 and the bed-side stop band 36 is a combination of materials having good sliding properties, for example, both are silk fabrics. Is preferred. For the same purpose as above, it is preferable that the pillowcase 12 and the sheets 34 are also made of a combination of cloths having good sliding properties. However, fabrics with good slidability are not always optimal for the original purpose of the pillowcases and sheets (for example, cotton). There are some problems. Therefore, it is preferable that at least only the area corresponding to the pillow bottom of the pillow cover and the area corresponding to the range in which the pillow of the sheet slides be a combination of cloths having good sliding properties. That is, at least the above-mentioned area portion is made of a cloth having a better sliding property than the cloth of the other areas.
[0028]
In addition, it is preferable to secure good slidability between the surface of the pillow 10 and the inner surface (back cloth) of the pillow cover 12. When the back is raised, if the pillow 10 (pillow cover 12) does not slide smoothly for some reason, the head is pulled by the pillow cover 12 (pillow 10), and a sense of dragging occurs. This is because the pillow cover 12 is relatively displaced with respect to the pillow 10 by the above-described operation, and the above-mentioned dragging time is reduced.
[0029]
As described above, the present invention has been described based on the embodiments. However, it is needless to say that the present invention is not limited to the above-described embodiments. For example, the following embodiments are also possible.
(1) In the above embodiment, the length direction of the bed-side stop band is aligned with the cross-bed direction, and the end of the bed-side stop band facing the cross-bed direction is fixed to the sheet surface.

However, the relationship of the direction in which the both stopper bands are provided may be reversed.
[0030]
That is, the length direction of the bed-side stopper band is aligned with the bed longitudinal direction, and the end of the bed-side stopper band facing the bed longitudinal direction is fixed to the sheet surface. The length direction of the band may be aligned with the longitudinal direction (bed cross direction) of the pillow (pillow cover), and the end of the pillow side stopper band facing the cross direction of the bed may be fixed to the pillow cover. In this case, in order to allow displacement of the pillow in the longitudinal direction of the bed and to restrict displacement in the transverse direction, the length of the non-fastened portion of the pillow-side stopper and the width of the bed-side stopper are substantially the same. The length of the non-fastened portion of the bed-side stop band is set longer than the width of the pillow-side stop band by the allowable displacement amount.
