Description

  The present invention relates to a pillow whose height can be adjusted by increasing or decreasing the amount of filling, and when the amount of filling is reduced and the height thereof is lowered, the pillow does not cause the user to feel the bottom. About. In addition, the height can be raised or lowered without increasing or decreasing the amount of filling.

  Conventionally, it has been generally performed to change the height of a pillow in use according to the physical condition. For this reason, a pillow (see Patent Documents 1 and 2) that adjusts the height by providing a filling port in the side bag of the pillow, appropriately increasing or decreasing the amount of the filling according to preference, has been considered.

However, with this configuration, the volume of the bag that fills the filling is constant, and the amount of filling changes in the bag. Therefore, if the amount of filling is small, the filling of the part where the head and the pillow come into contact with the pillow is in use. The weight of the head is eliminated without being fully supported, the amount of padding between the head and the bottom side is reduced, or there is no so-called bottoming feeling, it is difficult to obtain the desired height, and cushioning Was damaged and inferior in usability.
Utility Model Registration No. 3090217 JP 2001-128824 A

  In view of the above points, in the present invention, when the height of the pillow is changed by increasing or decreasing the amount of filling in the bag, the amount of filling in the bag is reduced by simply reducing the amount of filling in the bag. As the filling rate decreases, an extra space is created in the bag. For this reason, the movement of the filling becomes easy in the excess space of the bag body, and when the amount of the filling in contact with the head is reduced, a so-called feeling of bottoming is observed. An object of the present invention is to eliminate the occurrence of bottoming even when the filling is removed. It is another object of the present invention to change the filling rate of the filling by changing the volume of the bag itself without increasing or decreasing the amount of filling, thereby changing the height and softness of the pillow.

The pillow according to the first aspect of the present invention is a pillow comprising a plurality of small chambers partitioned between the upper and lower sides by a cloth, and a first locking member is provided at an extended portion of the cloth extending outside the side ground. A second locking member that engages with the first locking member provided on the extension portion at a plurality of positions on the side ground where the distance from the contact point between the side ground and the cloth extension is different. It is possible to change the height of the cloth by changing the engagement position between the first locking member and the second locking member.
In the pillow according to the second aspect of the present invention, the filling chamber is provided in each of the small chambers.
The pillow of the present invention according to claim 3 is a cloth that can change the height of the cloth by changing the engagement position of the first locking member and the second locking member. Filling is performed in a plurality of small chambers configured by partitioning them.
The pillow of the present invention according to claim 4 is a cylindrical cloth that can change the height of the cloth by changing the engagement position of the first locking member and the second locking member. An air circulation space configured between the upper and lower sides is provided.

  In the pillow according to the present invention, when the height is adjusted by reducing the amount of filling in the small chamber filled with the filling, the porosity of the small chamber is reduced by reducing the volume of the small chamber according to the amount of filling reduced. ing. For this reason, even if the amount of filling is reduced, there is no excess space in the small room and the movement of the filling is small. As a result, due to the load from the head, the filling is eliminated in the small room and the upper and lower sides of the pillow are removed. Can be used with good cushioning properties without causing a so-called bottoming feeling in contact with or close to that. Further, in order to change the filling rate of the filling by changing the volume of the bag body without increasing / decreasing the amount of filling, a first locking member provided at the extension portion of the cloth is engaged with the first locking member. By changing the engagement position with the second locking member, the volume of the bag can be changed by changing the height of the cloth, and the amount of filling to be filled is unchanged. Can change and the height and softness of the pillow can be changed accordingly.

  The pillow according to the present invention reduces the space product of the small chamber corresponding to the changed amount of filling, by generating the feeling of bottoming when the amount of filling in the pillow is changed in order to adjust the height of the pillow in use. It was prevented by changing and always increasing the filling rate in the space. In addition, when changing the height of the pillow without changing the amount of filling, change the space volume of the small room by changing the height of the cloth, change the filling rate of the filling in the small room space, The pillow is hard and high by increasing the filling rate, and the pillow is soft and low by decreasing the filling rate.

  As for the movement of the filling in the small chamber filled with the filling of the pillow bag body, the smaller the density of the filling in the small chamber, the less the pressure the filling itself receives from the surroundings, and the small chamber moves with a small load. For this reason, when the head is placed on the pillow, if the density of the filling is low, the filling is easily pushed away and there is no filling between the side surface of the bottom and the head, so that the bottoming occurs, so the filling is always received from the head. It must be under ambient pressure to withstand the load. However, when the filling is removed from the small chamber in order to reduce the height of the pillow, the above condition cannot be satisfied, and the relationship between the volume of the small chamber and the density of the filling is broken, resulting in bottoming out. In order to prevent this, the volume of the small chamber may be reduced. However, in the case of a pillow, it is common to form a bag by overlapping the top side and the bottom side and sewing the periphery. Therefore, in order to reduce the volume of the small chamber, it is easier to change the height of the cloth separating the top side and the bottom side than to change the area of the top and / or bottom side. Therefore, according to the present invention, the height of the cloth is changed by appropriately folding the cloth and fixing its end.

  FIG. 1 is an overall perspective view of a pillow 1 embodying the present invention, FIG. 2 is a cross-sectional view of the cloth 4, and FIG. 3 is a plan view. The pillow 1 is formed by integrating the peripheral edges of the front side ground 2 and the bottom side ground 3 by appropriate means by sewing or the like, and a plurality of small chambers 5a, 5b and 5c are formed. Each of the small chambers 5a, 5b, and 5c is provided with a filling means 7 made of a tubular knitted fabric so that the filling 6 can be taken into and out of the room appropriately. The filling filling means 7 is a tubular knitted fabric that is normally crushed flat, pushes it open to fill the filling 6 into the small chamber. When a predetermined amount of the filling 6 is filled, the filling means 7 is folded flat and pushed into the small chambers 5 to prevent the filling from escaping out of the pillow. The filling means 7 may be provided with an opening in each small chamber, and although not shown, the opening can be opened and closed with a fastener or the like.

  A cross section of the cloth 4 is shown in FIG. The cloth 4 is integrally formed with two pieces of cloth 4a and 4b sewn on the front side cloth 2 and the bottom face cloth 3 and a cloth 4c sandwiched between them and having an extended portion 8 longer than the cloth 4a and 4b. 4d. The extension portion 8 is in a free state. A first locking member 9 such as a button or a hook-and-loop fastener is attached to the end of the extension portion 8. And the 2nd latching members 10a, 10b, and 10c engaged with the said latching member 9 are provided in the several position from which the distance from the said cloth 4 differs.

In the pillow 1 of the present invention, when the small chambers 5a, 5b, 5c are sufficiently filled, the extension portion 8 of the cloth 4 is in a free state or is the second member that is closest to the cloth 4. It is engaged with the stop member 10a. And when the quantity of the filling in a small chamber is reduced, it is made to engage with the 2nd locking member 10b or 10c according to the quantity. By this engagement, the front side ground 2 of the portion is drawn closer to the cloth 4 and, as a result, the volume of the small chamber 5 is reduced. By reducing the volume of the small chamber 5 described above, the volume ratio occupied by the filling in the small chamber space does not decrease even if the amount of the filling filled in the small chamber 5 is small. Even if the load of the part is applied, the filling does not move unnecessarily, and a feeling of bottoming does not occur.
In order to change the height of the pillow without changing the amount of filling in the small chamber at all and to change the degree of hardness, the first locking member 9 of the extension part 8 of the cloth 4 is desired as described above. It is engaged with one of the second locking members according to the height. As a result, the height of the lining cloth constituting the chamber changes and the chamber volume also changes, so that the filling density changes, and the height hardness of the pillow can be selected as appropriate.

  As another embodiment, by providing a cylindrical basket 20 between appropriate positions of the pillow, for example, the center front side surface and the bottom side side ground, an air circulation space not filled with filling is created in the part, and the air flow inside There is a pillow that has improved. Since the height of the pillow also needs to be adjusted, the length of the cylindrical basket 20 can be changed.

  The cylindrical basket 20 shown in FIG. 3B has a square shape, and extending portions 21a and 22a are extended to the two facing cloths 21 and 22, and locking members 23 and 24 such as buttons and hook-and-loop fasteners are provided on the portions. Provide. Then, second locking members 25a, 25b, 26a, and 26b that engage with the locking members 23 and 24, respectively, are provided at a plurality of positions on the upper ground that face when the extended portions 21a and 22a are folded back. Yes. As the locking members 23 and 24 change their positions with the locking members 25a and 25b and 26a and 26b, respectively, the height of the cylindrical rod 20 becomes lower.

  The second embodiment is preferably provided in a portion that receives the back of the head of the central portion of the pillow, but may be provided in another portion, and may be used in combination with the first embodiment.

  In both the first and second embodiments, the extension portion 8 and the locking member are provided on the upper side ground, but it is possible to reverse the top and bottom and provide the locking member on the bottom side. Of course, it is possible to use a surface without a member on the head.

  In consideration of the amount of the filling to be accommodated in the small chamber, the accommodation space product of the small chamber can be changed, and this can be applied to the accommodation means for accommodating the filling with a constant filling rate in the accommodation space.

The whole perspective view of this invention pillow. Sectional drawing of a heel part. A is a plan view of the first embodiment, and B is a plan view of the second embodiment.
