Description

  The present invention relates to a mattress selection system for selecting a mattress suitable for a user by combining any one of a plurality of types of support layer portions and any of a plurality of types of surface layer portions.

  Conventionally, a mattress selection system of this type has been proposed that measures a user's body shape and selects a bedding (mattress) having a hardness suitable for the user based on the measured body shape (for example, a patent) Reference 1). In this system, the uneven shape of the back of the person being measured (the amount of depression on the waist and the amount of protrusion of the back) was measured, and the height and weight of the person to be measured were measured to determine the degree of obesity (BMI). Based on the uneven shape of the back and the obesity obtained, a bedding having a hardness suitable for the subject is selected.

JP 2003-219935 A

  However, simply selecting the hardness of the bedding as in the selection system described above may not necessarily be a suitable bedding for the user. For example, for users with a high degree of obesity and a tendency to warp and lower back, the selection system described above recommends a hard mattress to support the weight firmly, but in this case, the waist may be low when lying on its back. It tends to float and may cause back pain.

  The main object of the mattress selection system of the present invention is to provide a system capable of selecting a mattress more suitable for the user.

  The mattress selection system of the present invention adopts the following means in order to achieve the main object described above.

The mattress selection system of the present invention is
A mattress suitable for the user is selected by combining one of a plurality of types of support layer portions having different hardnesses and one of a plurality of types of surface layer portions having different thicknesses or materials disposed on the support layer portion. A mattress selection system,
An acquisition unit for acquiring the obesity level or weight and pelvic state of the user;
One of the plurality of types of support layer portions is selected based on the acquired degree of obesity or the weight, and any of the plurality of types of surface layer portions is selected based on the acquired pelvic state. A selection section for selecting or
An output unit for outputting the type of the selected support layer unit and the type of the surface layer unit;
It is a summary to provide.

  The mattress selection system of the present invention combines any one of a plurality of types of support layer portions having different hardness with any one of a plurality of types of surface layer portions having different thicknesses or materials arranged on the support layer portion. A mattress suitable for the user is selected. In this mattress selection system, one of a plurality of types of support layer portions is selected based on the degree of obesity or weight of the user, and one of a plurality of types of surface layer portions is selected based on the pelvic state of the user. select. In this way, it is possible to select a mattress that is more suitable for the user by separately selecting the support layer part for each degree of obesity or weight of the user and the surface layer part for each pelvic condition and combining them together. Become. Here, the pelvic state means a state (pelvic angle) such as a forward inclined state or a backward inclined state.

  In such a mattress selection system of the present invention, the selection unit may select a surface layer portion that is thick enough to determine that the pelvic state is a strong tendency to warp and waist (the pelvis is tilted forward). By doing so, it is possible to select a mattress that does not float and has a low burden on the waist.

  In the mattress selection system of the present invention, the acquisition unit further acquires a state of the neck of the user, and the selection unit further selects the acquired neck of a plurality of types of pillows to be combined with the mattress. A pillow whose height is so high that it is determined that the state tends to be stooped (neck tilted forward) may be selected, and the output unit may output the type of the selected pillow. By doing so, it becomes possible to provide a bedding more suitable for the user by combining the pillow and the mattress.

  Furthermore, in the mattress selection system according to the present invention, the acquisition unit further acquires either the supine position or the landscape orientation as the sleeping posture of the user, and the selection portion is turned upright when the acquired sleeping posture is the landscape orientation. It is good also as what selects the support layer part whose hardness is soft compared with the case of. If it carries out like this, it will become possible to respond | correspond appropriately to any sleeping position, without preparing a support layer part for exclusive use in each of lying on its back and sleeping on its side.

  The mattress selection system of the present invention further includes a non-contact measurement device that measures the shape of the back of the user in a non-contact manner, and the acquisition unit is based on the shape of the back measured by the non-contact measurement device. The pelvic state may be acquired. By so doing, it is possible to reduce the burden on the user when measuring the shape of the user's back compared to the case of using a contact-type measuring device.

  DESCRIPTION OF EMBODIMENTS Embodiments for carrying out the present invention will be described with reference to the drawings.

  FIG. 1 is a configuration diagram showing an outline of a configuration of a mattress selection system 20 as an embodiment of the present invention. 2 is an exploded perspective view of the mattress 50, FIG. 3 is a cross-sectional view of the mattress 50, and FIG. 4 is an external view of the pillow 60.

  The mattress 50 to be selected by the mattress selection system 20 is used by being placed on the floor of the bed, and as shown in FIGS. 2 and 3, a concave portion 52b recessed in a substantially cubic shape on the surface side excluding the peripheral portion 52a. A base member 52, a cushion member 54 as a support layer portion inserted into the recess 52 b of the base member 52, and an upper cover member 56 as a surface layer portion covering the peripheral edge portion 52 a of the base member 52 and the cushion member 54. It is comprised by. The side surface and the bottom surface of the base member 52 are covered with a box-shaped lower cover member 58, and the lower cover member 58 is connected to the upper cover member 56 by a fastener (not shown).

  The base member 52 is made of, for example, high density urethane. As the base member 52, a plurality of types of base members 52 formed of urethane materials having different hardnesses are prepared. In this embodiment, there are four types of base members 52 of “substantially soft”, “soft”, “standard”, and “hard”.

  In this embodiment, the cushion member 54 is divided into a head side cushion member that supports from the shoulder of the user M to the vicinity of the buttocks and a foot side cushion member that supports the foot of the user M. The cushion member 54 may be divided into three or more, or may not be divided.

  As shown in FIG. 3, each cushion member 54 covers the entire plate-shaped pedestal portion 54 a, a large number of columnar members 54 b erected on the upper surface of the pedestal portion 54 a with a predetermined interval. A cover member that does not. The pedestal portion 54a is made of foamed urethane. The columnar member 54b is formed in a columnar shape, and the bottom surface is bonded to the pedestal portion 54a with an adhesive. The columnar member 54b is formed of a low-hardness elastomer resin (for example, a styrene-based elastomer resin, a urethane-based elastomer resin, an ethylene-based air resin, or the like) so that it can be elastically deformed with a hardness smaller than that of the pedestal portion 54a. When a load is applied to the upper surface (pressure receiving surface), the columnar member 54b is elastically deformed so that the area of the pressure receiving surface increases and the height of the columnar member 54b decreases as the load increases. When the load applied to the pressure receiving surface reaches a certain load or more, the adjacent columnar members 54b come into contact with each other, and the height of the columnar member 54b does not change any more. As a result, when the mattress 50 is used, even if a large load (load from the heel portion) is applied to the cushion portion 54, the sinking amount of the cushion member 54 can be limited within a certain range. . In addition, since the columnar member 54b is in close contact with the body shape of the user M, the body pressure can be effectively dispersed and a comfortable feeling of use can be provided. In this embodiment, the columnar member 54b is formed in a columnar shape, but the shape thereof may be a rectangular column or an elliptical column. Further, the columnar member 54b is not limited to one formed of an elastomer resin, and may be formed of foamed rubber or a bag body filled with a fluid or gel. In the mattress 50 of the present embodiment, a support layer portion that supports the weight of the user is configured by the base member 52 and the cushion member 54. By selecting the base member 52 from a plurality of types, the support layer portion is used by the user. It is possible to change to a hardness suitable for.

  In the present embodiment, a plurality of types of cover members having different thicknesses and materials are prepared for the upper cover member 56. In the present embodiment, three types of “slightly thin”, “standard” and “slightly thick” are prepared as the upper cover member 56. The “slightly thin” is configured as, for example, a quilt portion in which a wrinkle is disposed between the front fabric portion and the back fabric portion. The “standard” is configured, for example, as a quilt portion in which a urethane sheet is inserted between a “slightly thin” front fabric portion and a back fabric portion. “Slightly thicker” is configured, for example, as a fiber structure formed by three-dimensionally knitting resin fibers such as polyethylene in the lower layer of “slightly thinner”. The thicker the upper cover member 56, the easier it is to fit the unevenness of the user M's body.

  The pillow 60 combined with the mattress 50 includes a pillow body 62 and a spacer 64. The spacer 64 is an adjustment sheet that is laid on the bottom of the pillow body 62 and adjusts the height of the pillow 60. In this embodiment, an adjustment sheet 64a having a thickness of 5 mm and an adjustment sheet 64b having a thickness of 10 mm are prepared. ing. Accordingly, the height of the pillow 60 can be raised by 5 mm from the standard by laying one adjustment sheet 64a on the pillow body 62, and the height of the pillow 60 can be raised by 10 mm from the standard by laying one adjustment sheet 64b. In addition, the height of the pillow 60 can be increased by 15 mm from the standard by laying the adjustment sheets 64a and 64b one by one. Of course, if the spacer 64 is not laid, the pillow 60 can be used at a standard height.

  The mattress selection system 20 according to the embodiment selects a mattress 50 suitable for the user M by combining any one of a plurality of types of cushion members 54 and one of a plurality of types of mattress seat members 56, and a pillow 60 combined with the mattress 50. Is to be selected. As shown in FIG. 1, the mattress selection system 20 includes a three-dimensional measuring device 22 that measures the body shape (mainly unevenness of the back) of the user M, and a computer 30.

  Although not shown, the three-dimensional measuring device 22 includes a structured light irradiation device that projects a predetermined pattern of structured light using infrared rays on a measurement subject (user M), an infrared camera that images the measurement subject, and the like. And measuring the position (depth) of each point on the captured image using triangulation.

  The computer 30 is configured as a general-purpose computer having an external storage device such as a CPU, ROM, RAM, hard disk drive and flash memory drive (SSD) (not shown) and various interfaces, and is used as a display device 42 such as a liquid crystal display and an input device. And connected to a keyboard 44 or a mouse. The computer 30 is installed with a selection program for selecting the mattress 50 and the pillow 60 suitable for the user M from a plurality of types. The computer 30 has an input unit 32, a mattress data storage unit 34, a pillow data storage unit 35, a selection unit 36, and a display control unit 38 as functional blocks. Hardware such as 30 CPUs, ROMs, RAMs, external storage devices and various interfaces, and software including an installed selection program function together. The input unit 32 inputs necessary user information (such as the height and weight of the user M, main sleeping posture, etc.) from the keyboard 44 and a mouse, and 3D measurement data measured by the 3D measurement device 22. . Further, as shown in FIG. 5, the mattress data storage unit 34 has a sleeping posture, user classification information (zone, mattress zone Zm), the thickness of the upper cover member 56 (surface layer material), and a cushion member 54 (supporting). The thickness of the layer portion material) and the product name are stored in association with each other. As shown in FIG. 6, the pillow data storage unit 35 has a sleeping posture, user classification information (zone, pillow zone Zp), pillow height, product name, and presence / absence of an adjustment sheet (presence / absence of a 5 mm adjustment sheet 64a, 10 mm). The presence or absence of the adjustment sheet 64b is stored in association with each other. Each data in the mattress data storage unit 34 and the pillow data storage unit 35 is made into a database, and data can be deleted, changed, and added as appropriate in accordance with changes in the product lineup and product specifications. The selection unit 36 classifies the zone into a plurality of zones (mattress zone Zm, pillow zone Zp) according to the body shape of the user M, and determines the hardness of the cushion member 54 of the mattress 50 and the thickness of the upper cover member 56 and the pillow according to each zone. The height of 60 is selected from a plurality of types prepared in advance. The display control unit 38 performs display control for displaying a screen for inputting user information on the display device 42 and for displaying a selection result by the selection unit 36 on the display device 42.

  Next, the operation of the mattress selection system 20 configured as described above, particularly, the operation of the selection unit 36 will be described. FIG. 7 is a flowchart illustrating an example of selection processing executed by the selection unit 36 of the computer 30. This process is executed based on an instruction from the operator.

  When the selection process is executed, the computer 30 first inputs data necessary for selection of the height (m), weight (kg), sleeping posture SP, etc. of the user M via the input unit 32 (step S100). ). As the sleeping posture SP, one selected by the user M among the supine and sideways directions is input. Subsequently, based on the height and weight of the user M, for example, the body weight is divided by the height squared to calculate the degree of obesity (BMI) (step S110). Next, the three-dimensional measurement data of the user M formed by the three-dimensional measurement device 22 is input (step S120), and the pelvis angle θp and the neck angle θn of the user M are determined based on the input three-dimensional measurement data. Calculate (step S130). Note that the pelvic angle θp is a parameter for determining the forward tilt state (warp waist) and the backward tilt state (flat back) of the pelvis, and is based on three-dimensional measurement data (coordinates of each measurement point of the human body) For example, in the side view of the user M, the angle is calculated based on an angle formed with respect to a vertical plane of a line connecting the most protruding point of the buttocks and the most depressed point of the waist. Further, the neck angle θn is a parameter for determining the forward tilt state of the neck (the back of the neck), and based on the three-dimensional measurement data, for example, the vertical line of the line connecting the base of the neck and the center of the head Calculated according to the angle formed with respect to the surface.

  Then, the mattress zone which is a classification of the user M for selecting the mattress 50 based on the sleeping posture SP input in step S100, the obesity level (BMI) calculated in step S110, and the pelvic angle θp calculated in step S130. Zm is set (step S140). FIG. 8 is an explanatory diagram showing an example of a mattress zone setting table. As shown in the figure, the mattress zone setting table includes a lying mattress zone setting table (see FIG. 8A) with the sleeping posture SP lying on its back, and a horizontal mattress zone setting table with the sleeping posture SP lying horizontally (see FIG. 8). 8 (b)). The mattress zone setting table for supine divides obesity level (BMI) into three (small), medium (standard), and large (obesity), and pelvic angle θp is small (flat back), medium (normal) , Large (warped waist), and is classified into a total of nine zones according to each combination. The same applies to the mattress zone setting table for landscape orientation. For example, when the sleeping posture SP is on the back, the degree of obesity (BMI) is large (obesity), and the pelvic angle θp is large (warp waist), “C3” is set as the mattress zone Zm. Although the mattress zone setting table is divided into nine zones, the number of divisions may be any number.

  When the mattress zone Zm is set, the mattress shown in FIG. 5 shows the hardness of the cushion member 54 (support layer material) corresponding to the set mattress zone Zm, the thickness of the upper cover member 56 (surface layer material), and the recommended product name. Read from the data storage unit 34 (step S150). As shown in FIGS. 5 and 8A, when the sleeping posture SP is on its back, the cushion member 54 has a hardness when the obesity degree (BMI) is small (skinny), that is, the mattress zone Zm is A1, A2. Or when “A3”, “soft” is selected, and when the obesity level (BMI) is medium (standard), that is, when the mattress zone Zm is B1, B2 or B3, “soft” and “standard” are selected. When the degree of obesity (BMI) is large (obesity), that is, when the mattress zone Zm is C1, C2 or C3, “hard” is selected. On the other hand, when the sleeping posture SP is sideways, as shown in FIG. 5 and FIG. 8B, when the obesity degree (BMI) is small (skinny), that is, when the mattress zone Zm is A4, A5 or A6, When “substantially soft” is selected and the body mass (BMI) is medium (standard), that is, when the mattress zone Zm is B4, B5 or B6, “soft” and “standard” are selected, and the body weight ( When (BMI) is large (obesity), that is, when the mattress zone Zm is C4, C5 or C6, “standard” and “hard” are selected. As described above, the hardness of the cushion member 54 (support layer material) is selected as the obesity degree (BMI) increases. Thereby, the weight of the user M can be supported firmly and the excessive subduction of the site | part (buttock part) with a big load can be suppressed. In addition, when the sleeping posture SP is in the horizontal direction, a softer one is selected as compared to the case of lying on the back so that the shoulder portion is depressed to some extent and the posture of lying down can be taken comfortably.

  Further, when the sleeping posture SP is on its back, the thickness of the upper cover member 56 is, as shown in FIGS. 5 and 8A, when the pelvic angle θp is small (flat back), that is, when the mattress zone Zm is A1, When B1 or C1, “slightly thin” is selected, and when the pelvic angle θp is medium (normal), that is, when the mattress zone Zm is A2, B2 or C2, “standard” is selected and the pelvic angle θp is large. When (warp waist), that is, when the mattress zone Zm is A3, B3 or C3, “slightly thicker” is selected. On the other hand, when the sleeping posture SP is sideways, as shown in FIGS. 5 and 8B, when the pelvic angle θp is small (flat back), that is, when the mattress zone Zm is A4, B4, or C4, When “thin” is selected and the pelvic angle θp is medium (normal), that is, when the mattress zone Zm is A5, B5, or C5, “standard” is selected, and when the pelvic angle θp is large (warp waist), that is, When the mattress zone Zm is A6, B6 or C6, “slightly thicker” is selected. As described above, the thickness of the upper cover member 56 is selected so as to increase the tendency to warp and waist regardless of the degree of obesity (BMI). In the present embodiment, as shown in FIG. 5, the thickness of the upper cover member 56 is such that the same thickness is selected at the same pelvic angle θp regardless of whether the sleeping posture SP is on its back or sideways. It was.

  Here, for example, for the user M with a large degree of obesity (BMI) (obesity), “hard” is selected as the cushion member 54 (support layer material), but at the same time the pelvic angle θp is large (warp). If it is waist), the waist may float and the burden on the waist may become excessive. In the present embodiment, for the user M whose pelvic angle θp is large (warp waist), “thick” is selected as the upper cover member 56 (surface layer material). The upper cover member 56 can fit the unevenness of the lumbar region while firmly supporting the body weight, thereby reducing the burden on the lumbar region. Thus, the mattress more suitable for the user M can be obtained by separately selecting and combining the cushion member 54 for each obesity (BMI) of the user M and the upper cover member 56 for each pelvic angle θp. 50 can be selected.

  Next, the classification of the user M for selecting the pillow 60 based on the sleeping posture SP input in step S100, the obesity level (BMI) calculated in step S110, and the neck angle θn calculated in step S130. A pillow zone Zp is set (step S160). FIG. 9 is an explanatory diagram showing an example of a pillow zone setting table. As shown in the figure, the pillow zone setting table includes a lying pillow zone setting table (see FIG. 9A) with the sleeping posture SP on its back, and a horizontal pillow zone setting table with the sleeping posture SP lying horizontally (see FIG. 9). 9 (b)). The pillow zone setting table for supine divides obesity (BMI) into three (small), medium (standard), and large (obesity), and the neck angle θn (prone tendency) is small (normal). It is divided into three (medium (somewhat present)) and large (present), and a total of nine zones are classified according to each combination. The same applies to the sideways pillow zone setting table. For example, when the sleeping posture SP is on the back, the degree of obesity (BMI) is large (obesity), and the neck angle θn is large (present), “c3” is set as the pillow zone Zp. Although the pillow zone setting table is divided into nine zones, the number of divisions may be any number.

  When the pillow zone Zp is set, the pillow height corresponding to the set pillow zone Zp, the recommended product name, and the presence / absence of the adjustment sheets 64a and 64b are read from the pillow data storage unit 35 (step S170). As shown in FIGS. 6 and 9A, the height of the pillow 60 (the pillow height) is such that the neck angle θn is small (no stoop) and the degree of obesity (BMI) when the sleeping posture SP is on its back. Is small (skinned) or medium (standard), that is, when the pillow zone Zp is a1 or b1, “standard” not using the adjustment sheets 64a and 64b is selected, and the neck angle θn is small (no back). And when the obesity level (BMI) is large (obesity) or the neck angle θn is medium (slightly stooped) and the obesity level (BMI) is small (lean) or medium (standard), that is, the pillow zone Zp is In the case of c1, a2 or b2, “slightly higher” using one 5 mm adjustment sheet 64a is selected. In addition, the neck angle θn is medium (slightly stooped) and the degree of obesity (BMI) is large (obesity), or the neck angle θn is large (with stooped back) and the degree of obesity (BMI) is small (lean). Or, when medium (standard), that is, when the pillow zone Zp is c2, a3 or b3, “slightly high” using one 10 mm adjustment sheet 64b is selected and the neck angle θn is large (there is a stoop) ) And the degree of obesity (BMI) is large (obesity), that is, when the pillow zone Zp is c3, “high” is selected to use the 5 mm adjustment sheet 64a and the 10 mm adjustment sheet 64b one by one. . On the other hand, when the sleeping posture SP is in the landscape orientation, as shown in FIGS. 6 and 9B, in this embodiment, the sleeping posture SP is in the supine position for the same neck angle θn and obesity level (BMI). The same pillow height is selected. This is because, even for the user M who has determined that the sleeping posture SP is in the landscape orientation, the sleeping time on the back is actually longer than the lying on the sleeping posture, and the burden on the neck is greater when the height of the pillow 60 is adjusted to the lying on the back. Based on what is considered to be less. Of course, when the sleeping posture SP is in the horizontal direction, a higher pillow height may be selected for the same neck angle θn and obesity level (BMI) than when lying on the back.

  Thus, when the mattress 50 and the pillow 60 are read out, such as the hardness of the cushion member 54 (support layer material), the thickness of the upper cover member 56 (surface layer material), the height of the pillow 60, and the name of each product. The display control unit 38 is controlled so that the read information is displayed on the display device 44 as a selection result display screen (step S180), and the selection process is terminated. An example of the selection result display screen is shown in FIG. As shown in the figure, on the selection result display screen, the measurement information (BMI value, sleeping posture SP and back tendency) of the user M, the recommended upper cover member 56 (surface layer portion) of the mattress 50 and the cushion member 54 (support) are displayed. Material information (layer portion thickness, support layer material hardness and product name) and recommended pillow 60 height information (product name and number of adjustment sheets) are displayed. The user M can easily find the mattress 50 and the pillow 60 that can provide a comfortable sleep by referring to the display contents of the selection result display screen.

  According to the mattress selection system 20 of the present embodiment described above, one of a plurality of types of cushion members 54 (support layer portions) is selected based on the degree of obesity (BMI) of the user M, and the user M One of a plurality of types of upper cover members 56 (surface layer portions) is selected based on the pelvic angle θp. As described above, the cushion member 54 for each degree of obesity of the user M and the upper cover member 56 for each pelvic angle θp are separately selected and combined to select the mattress 50 that is more suitable for the user M. Is possible.

  In the mattress selection system 20 of the present embodiment, the thickness of the upper cover member 56 (surface layer material) is selected based on the pelvic angle θp, so that the thickness increases as the warp / waist tendency increases. However, it is possible to select the mattress 50 with less burden on the waist.

  Furthermore, in the mattress selection system 20 according to the present embodiment, the height of the pillow 60 is selected based on the angle θn of the neck, so that the higher the tendency toward the back of the neck (forward tilt), the higher the height. By the combination, the bedding more suitable for the user M can be provided.

  Further, in the mattress selection system 20 of the present embodiment, as the hardness of the cushion member 54, when the sleeping posture SP is in the horizontal direction, the softness is selected as compared with the case of lying on the back. Thus, any sleeping posture can be appropriately handled without preparing a dedicated cushion member.

  In the present embodiment, the body shape of the user M (irregularities on the back) is measured using the non-contact type three-dimensional measuring device 22, but the present invention is not limited to this, and any other measuring device can be used. It may be used, or may be measured by a store staff or the like using a measure and input using the keyboard 44 or the like.

  In this embodiment, the degree of obesity (BMI) is calculated based on the height and weight of the user M, and one of a plurality of types of base members 52 having different hardnesses is selected based on the calculated degree of obesity (BMI). However, the present invention is not limited to this, and any one of a plurality of types of base members 52 may be selected based on the weight of the user M, and different conditions may be used for selecting the base member 52. May be added.

  In the present embodiment, a plurality of types of base members 52 formed of base urethane materials having different hardnesses are prepared, and a support including the base portion 52 and the cushion portion 54 is selected by appropriately selecting the plurality of types of base portions 52. The hardness of the layer portion was changed. However, the present invention is not limited to this, and a plurality of types of cushion members 54 having different hardnesses may be prepared, and the hardness of the support layer portion may be changed by appropriately selecting the plurality of types of cushion members 54. And you may comprise a support layer part with the combination of the multiple types of base member 52 from which hardness differs, respectively, and the cushion member 54 from which hardness differs, respectively. In these cases, the cushion member 54 is not limited to one constituted by a large number of columnar members 54b, and may be constituted by a single member made of urethane foam or the like.

  In the present embodiment, the plurality of types of upper cover members 56 are formed with different thicknesses and materials, but those formed with different materials with the same thickness may be used, or with different thicknesses. You may use what was formed with the same raw material.

  In this embodiment, the pillow 60 combined with the mattress 50 is selected together with the selection of the mattress 50, but the selection of the pillow 60 may be omitted.

  In this embodiment, the selection result of the mattress 50 (the cushion member 54 and the upper cover member 56) is displayed on the display device 42, but may be printed on paper.
