Description

  The present invention relates to an assembly type mattress, and more particularly to an assembly type mattress for a bed that can be easily transported.

  As lifestyle changes to western style, it is becoming common for beds to be used in accommodation facilities such as homes and hotels. Many of these beds are relatively luxurious and sturdy. In other words, the bed frame is made to be durable enough to withstand long-term use and withstand heavy loads, and the mattress set in the bed is elegant with the use of cushioning materials such as springs. It is configured by covering with a rich mattress cover with a large thickness of about 15 cm. However, if the mattress is used for a long time, the cushioning property of the inner packaging material will deteriorate due to aging, and the mattress cover will be damaged or soiled. Has a short lifespan. When the mattress is damaged or damaged in this way, it is necessary to replace the mattress. In addition, the mattress is directly related to the sleeping comfort, and it is necessary to replace the mattress even when the sleeping comfort is poor. When the mattress needs to be replaced in this way, it is possible to select only the mattress or the entire bed.

  By the way, a bed is generally sold as furniture by a bed frame manufactured by a furniture manufacturer, and a mattress manufactured by a bedding manufacturer is set on the bed frame. In addition, furniture dealers are accustomed to transporting large items such as chests and cupboards, and are equipped with transport equipment such as large trucks and lifting equipment, so they can transport large items such as beds. Is always possible. However, bedding sellers generally handle products that can be folded and made smaller, such as futons, blankets, pillows, covers, etc., and do not always have transport equipment for carrying large items such as beds. Is normal.

  Therefore, a foldable mattress as shown in the following Patent Documents 1 to 3 has been proposed so that the mattress can be changed into a compact form so as to be convenient for conveyance.

Japanese Patent Laying-Open No. 2005-211399 JP-A-9-299196 Utility Model Registration No. 3084039

  However, the conventional foldable mattress as described above is divided into individual mats that are partially continuous to enable folding. Therefore, a step is produced at the boundary between the individual adjacent mats, and the cushioning property is lowered. There is a disadvantage that the sleeping comfort is poor due to the uncomfortable feeling caused by the step and the decrease in cushioning properties, and the present situation is that no contrivance has been made to eliminate this disadvantage. Further, as the mattress becomes thicker, this defect becomes more prominent. Therefore, a normal folding mattress having a size of 10 cm or less is employed.

  Therefore, the present inventor has conducted extensive research and paid attention to the fact that the mattress for the bed is usually placed on the bed and hardly needs to be folded. An assembly-type mattress has been invented that eliminates the above-described problem and that reduces the uncomfortable feeling as much as possible by preventing the change in cushioning due to a step at the boundary between adjacent mats as much as possible.

  The assembly type mattress according to the present invention is composed of a flat rectangular parallelepiped upper mat, a flat rectangular parallelepiped under mat stacked below, and a foldable mattress cover that can store the upper mat and the under mat in a stacked state. The upper mat is composed of a mat body made of a cushioning material, the mat body is composed of a plurality of mats each having the same width, and the under mat has the same width and the same length as the upper mat. None, consisting of mat pieces of the same width each divided into a plurality of cushioning materials, with the upper mat and the under mat being stacked, the adjacent boundary lines of each mat constituting the mat body in the upper mat, and the under The mating border of each mat piece does not overlap It is characterized in that it has urchin configuration.

  Further, in the assembly type mattress having the above structure, the upper mat is composed of an upper mat, an intermediate mat, and a lower mat each having the same width and divided into three parts with the head side facing up. The mat pieces having the same shape divided into four parts may be partially connected so that they can be folded in four.

  Further, in each assembly type mattress having the above-described configuration, the upper mat is composed of a mat body and an edge mat made of a cushioning material, and the edge mat is disposed so as to be applied to the left and right sides of the mat body. Each of the right and left outer frame bodies having the same width and divided in the length direction, and in the state where the upper mat and the under mat are stacked, each of the outer frame bodies constituting the edge mat in the upper mat You may comprise so that an adjacent boundary line may not overlap with the adjacent boundary line of each mat which comprises the mat main body in an upper mat, and the adjacent boundary line of each mat piece of an undermat.

  Furthermore, in each assembly type mattress of the said structure, you may comprise a mat body so that the bag body for raising a raising member may be provided in the lower surface.

  In each of the assembly type mattresses having the above-described configuration, the mattress cover may be a box type configured by a rectangular parallelepiped container body having an upper surface opened and a lid body closing the upper surface opening of the container body. .

  By constructing the assembly type mattress as described above, the upper mat, the under mat, and the mattress cover are separated, and the upper mat stacks the mats constituting the mat body, folds the under mat and the mattress cover, and the edge. When mats are provided, stacking the individual outer frames that make up the edge mat shortens the overall length of the mattress, making it as small as a normal mattress or comforter bedding. There is an advantage that a large transport device is not required.

  In addition, in the state where the upper mat and the under mat are laminated, the positions of the adjacent boundary lines of the mats constituting the mat body and the adjacent boundary lines of the mat pieces of the under mat do not overlap each other, and the edge When the mat is provided, the positions of the adjacent boundary lines of the outer frames constituting the edge mat and the adjacent boundary lines of the mats constituting the mat body and the adjacent boundary lines of the mat pieces of the under mat do not overlap each other. Since it comprised in this way, the level | step difference which arises in the boundary part between adjacent mats is relieve | moderated, and the cushioning property in the boundary part between the mats in a mattress becomes favorable, Therefore It becomes a mattress with good sleeping comfort in which a sense of incongruity is reduced.

  Furthermore, when the mat body is raised in the width direction of the lower surface, the mat body is raised according to the user's physique or preference, or partly sags are caused Can be repaired.

  Furthermore, there is an advantage that the upper mat and the under mat can be easily assembled and housed and disassembled by making the mattress cover a box type constituted by a container body having an upper opening and a lid.

It is a perspective view which shows the assembly state of the assembly-type mattress which concerns on an Example. It is a perspective view which shows the state which decomposed | disassembled and miniaturized the assembly-type mattress which concerns on an Example. It is a perspective view of the state which laminated the upper mat and the under mat in the assembly type mattress concerning an example. It is a perspective view which shows the state which accommodates the raising member in the mat of the mat main body in the assembly-type mattress which concerns on an Example.

  Hereinafter, an example of an assembly type mattress according to the present invention will be described in detail with reference to the accompanying drawings. In this embodiment, a single mattress is described. However, if the size is changed, the mattress can be applied to a semi-double mattress or a double mattress.

  FIG. 1 shows the assembly type mattress of the present embodiment in a landscape orientation, but in the description of the present embodiment, the side on which the head is located (right side in the drawing) is generally referred to as the upper side.

  1 to 4, A is an upper mat having a flat rectangular parallelepiped shape, and includes a mat body 10 and an edge mat 20. The mat body 10 has a rectangular parallelepiped shape of the same size divided into an upper mat 11, an intermediate mat 12, and a lower mat 13, and is covered with net bags 11a, 12a, and 13a, respectively. One mat has a width of 80 cm, a length of 66.6 cm, and a thickness of 9 cm. Each of the mats is a urethane mat having excellent cushioning properties in which the surface is profiled into wavy irregularities for the purpose of dispersing body pressure. In the present embodiment, such a profile-processed urethane mat is used. However, the present invention is not limited to this, and various urethane mats whose surfaces are processed in consideration of dispersion of body pressure and the surfaces are flat. A urethane mat may be used. Further, as shown in FIG. 5, bag bodies 11b, 12b, and 13b for storing raising members are provided in the width direction on the lower surfaces of the net bags 11a, 12a, and 13a covering each mat. By storing the raising member D in 11b, 12b, and 13b, the mat can be partially raised or cushioning can be added according to preference and when the mat sags.

  The edge mat 20 is disposed so as to be applied to both the left and right sides of the mat body 10, and maintains a shape retaining property of the upper mat A and has a cushioning property to strengthen the peripheral portion but is a slightly hard urethane. Consists of mats. That is, the edge mat 20 is composed of an outer frame body divided into three parts on the left and right sides. On the right side of the mat body 10, an upper right outer frame body having a width of 10 cm, a length of 60 cm, and a thickness of 9 cm in order from the top. 21, a right middle outer frame body 22 having a width of 10 cm, a length of 80 cm, and a thickness of 9 cm, a right lower outer frame body 23 having a width of 10 cm, a length of 60 cm and a thickness of 9 cm are disposed. An upper left outer frame body 24 having a width of 7 cm, a length of 80 cm and a thickness of 9 cm, and a lower left outer frame body 26 having a width of 7 cm, a length of 60 cm and a thickness of 9 cm are disposed. . Therefore, when the mats 11, 12, 13 constituting the mat body 10 and the outer frame bodies 21, 22, 23, 24, 25, 26 constituting the edge mat 20 are combined, the size of the entire upper mat A is The width is 97 cm, the length is 200 cm, and the thickness is 9 cm.

  The lengths of the mats 11, 12, 13 constituting the mat body are 66.6 cm, the lengths of the left, right, upper and lower outer frame bodies 21, 23, 24, 26 constituting the edge mat 20 are 60 cm, Since the outer frame bodies 22 and 25 at the center of the left and right are 80 cm, the adjacent boundary lines a and b of the mats 11, 12 and 13 constituting the mat body in the upper mat A and the edge mat 20 in the upper mat A are configured. The adjacent boundary lines c, d, e, and f of the outer frame bodies 21, 22, 23, 24, 25, and 26 are prevented from overlapping each other.

  In this embodiment, the upper mat A is provided with the edge mat 20, but the edge mat is not provided, and one mat has a size of 97 cm in width, 66.6 cm in length, and 9 cm in thickness. You may comprise an upper mat only from a main body. Further, in the present embodiment, the mat body 10 is divided into three parts, but the present invention is not limited to this, and in the state where the upper mat and the under mat are stacked as described later, The effect of the present invention can be achieved if it is satisfied that the adjacent boundary lines of the mats constituting the mat body do not overlap with the adjacent boundary lines of the mat pieces of the undermat.

  Furthermore, in this embodiment, the size of one mat is 80 cm in width, 66.6 cm in length, and 9 cm in thickness. However, the present invention is not limited to this, and each of the divided mats has the same width and the same thickness. The lengths may be different from each other, and the width and thickness can be appropriately changed under the condition that the divided mats have the same width and the same thickness. As a general modification, in the case of a semi-double bed, the mat width may be 97 cm, the edge mat may be 13 cm wide and 10 cm wide, and the total width may be 120 cm. In the case of a bed, the mat width may be 120 cm, and the edge mat may be 13 cm wide and 7 cm wide to have a total width of 140 cm. The reason for this irregular combination is that if three types of mats with widths of 80 cm, 97 cm, and 120 cm and three types of edge mats with widths of 7 cm, 10 cm, and 13 cm are prepared, a single bed can be used. This is because all combinations up to the double bed can be configured, and the necessity of the edge mat can be selected for the single bed and the semi-double bed.

  B is an undermat, and is formed by partially connecting mat pieces 31, 32, 33, and 34 having the same shape divided into four parts so that they can be folded in four. One mat piece has a width of 97 cm, a length of 50 cm, and a thickness of 6 cm, and the entire size of the undermat B is a flat rectangular parallelepiped shape having a width of 97 cm, a length of 200 cm, and a thickness of 6 cm, It has the same width and the same length as the upper mat A. Of course, if the size of the upper mat A changes, the size of the under mat B is also changed in accordance with the size of the upper mat A. The mat pieces 31, 32, 33, and 34 are made of a material having excellent cushioning properties for the mat body 10 that constitutes the upper mat A. Therefore, when the mat pieces 31, 32, 33, and 34 are made of a slightly hard urethane, the overall feeling of stability is improved. Maintained.

  In the state where the upper mat A and the under mat B are stacked, the contour boundaries a and b of the mats 11, 12, and 13 constituting the mat body 10 of the upper mat A are 66.6. cm and 133.2 cm. Adjacent boundary lines c, d, e, and f of the outer frames constituting the edge mat 20 of the upper mat A are located at 60 cm and 140 cm from the bottom. Adjacent boundary lines g, h, i of the mat pieces 31, 32, 33, 34 constituting the under mat B are located at 50 cm, 100 cm, and 150 cm from the bottom. Therefore, in the state where the upper mat A and the under mat B are stacked, the adjacent boundary lines c, d, e of the outer frame bodies 21, 22, 23, 24, 25, 26 constituting the edge mat 20 in the upper mat A are stacked. , F are configured so as not to overlap the adjacent boundary lines a, b of the mats 11, 12, 13 constituting the mat body 10 in the upper mat A and the adjacent boundary lines of the mat pieces of the under mat B and the upper The adjacent boundary lines of the mats constituting the mat body 10 in the mat A and the adjacent boundary lines g, h, i of the mat pieces 31, 32, 33, 34 of the under mat B are configured not to overlap. become. Since it comprised in this way, the level | step difference which arises in the boundary part between adjacent mats is relieve | moderated, and the cushioning property in the boundary part between the mat | matte in a mattress becomes favorable, Therefore It becomes a comfortable mattress which reduced the sense of incongruity.

  C is a mattress cover, which is formed of a foldable fabric. For example, a thick woven fabric suitable for a mattress for bed and a quilted fabric with batting are suitable. The mattress cover C is formed in a box shape including a rectangular parallelepiped container main body 40 whose upper surface is opened and a lid body 41 that closes the upper surface opening of the container main body. With this configuration, there is an advantage that the upper mat A and the under mat B can be easily assembled and stored and disassembled. In addition, it may not necessarily be a box type but a bag type.

  By constructing the assembly type mattress as described above, as shown in FIG. 3, the upper mat A, the under mat B, and the mattress cover C are separated, and the upper mat A separates the mats constituting the mat body 10 from each other. When stacked in three stages, the thickness is 27 cm, the width is 80 cm, and the length is 66.6 cm. When the undermat B is folded in four, the thickness is 24 cm, the width is 97 cm, and the length is 50 cm. When properly stacked and properly folded, the overall size will be as small as a normal mattress or comforter bedding, so a large transport device is required to transport large items. There are advantages to not.
