Description

  The present invention relates to a bedding for raising a back used in a mattress for raising one end of a longitudinal direction upward to raise a user's upper body.

  For example, if you want to support a user who has weak physical strength to wake up, or want to maintain a posture where the user wakes up to read or eat, the one end side of the mattress in the longitudinal direction is moved upward. I try to bend it.

  In order to curve the one end side in the longitudinal direction of the mattress upward, it is known to use a so-called wake-up bed apparatus (Patent Document 1). As another means, the mattress is constituted by a base unit, a bendable cushion body provided on the upper surface of the base unit, and an exterior body covering them. The base unit has a fixed hook part and a movable hook part, and the movable hook part is driven by a built-in driving source via a power transmission mechanism, so that the movable hook part, that is, one end side of the mattress is raised and lowered. It is known to make (Patent Document 2).

  In order to raise the user's upper body by the above-described means, if one end of the mattress in the longitudinal direction is bent upward, the mattress has a predetermined thickness dimension, so that the inner side of the curve corresponds to the thickness dimension. A compressive force is generated on the upper surface toward the inner side (center direction) of the mattress in the longitudinal direction, and a tensile force along the longitudinal direction is generated on the lower surface serving as the outer surface.

  Therefore, a compressive force generated on the upper surface of the mattress acts on the back surface of the user, and the back surface is pressed downward by the compressive force, and the abdomen is pulled backward (inside the curve), so that the abdomen is compressed. Sometimes.

  Therefore, when the mattress is bent and the upper body of the user is raised, a mattress for preventing a feeling of pressure on the user's abdomen has been put into practical use. A conventional mattress has an interior body and a bag-shaped exterior body that is formed of stretchable fabric and covers the interior body. It is configured by a layered member.

  Thereby, when the mattress is bent, the first layered member located on the upper side slides with respect to the second layered member while extending the exterior body, so that the compression of the mattress applied to the back surface of the user is performed. The force can be reduced compared to the overall thickness of the mattress.

Japanese Patent No. 3525027 JP 2009-136628 A

  By the way, the conventional mattress for reducing the compressive force applied to the user's back when raising the back must be constituted by the first layered member and the second layered member that can slide the interior body as described above. There wasn't.

  That is, a conventional back-up mattress has to adopt a different structure from existing mattresses in order to reduce the compressive force applied to the user's back when the back is raised. For this reason, a user who already owns a mattress has to purchase a new mattress, which is inconvenient and disadvantageous in terms of cost.

  An object of the present invention is to provide a mattress for raising the back of a mattress that can be attached to an existing mattress to reduce the compressive force applied to the back surface of the user when the back is raised.

FIG. 1 shows a state in which only the first drive shaft 16 is operated to drive the back floor portion 9 in the upward direction and the first leg floor portion 11 and the second leg floor portion 12 are not raised. Yes.

  The mattress 31 is placed on the upper surface of the floor plate body 6. The mattress 31 contains an elastic material such as urethane foam or a spring, and each floor portion of the floor plate body 6 is driven to undulate, so that the mattress 31 is elastically curved according to the undulation driving. It has become.

  A user U lies on the top surface of the mattress 31. As shown in FIG. 1, when the back floor portion 9 of the floor plate body 6 is driven upward, and the one end side in the longitudinal direction located on the back floor portion 9 side of the mattress 31 is bent upward. A compressive force is generated on the upper surface that is the inside of the curve of the mattress 31, and this compressive force acts on the back surface of the user U.

  Therefore, the mattress 31 is provided with a back-up bedding 32 for reducing the compression force generated on the upper surface from acting on the back surface of the user U when the mattress 31 is bent. This back-raised bedding 32 has a base member 33 and a sliding member 34.

  The base member 33 is made of a sheet-like material having lubricity and stretchability, such as a satin weave fabric, a sheet made of synthetic resin fibers such as polyester, a polyester knit fabric, and a stretchable urethane synthetic leather. As shown in FIG. 4, it is formed in a bag shape having a mirror part 33a covering the upper surface of the mattress 31, a town part 33b covering the outer peripheral surface, and an engaging part 33c engaging with the peripheral part of the lower surface.

  By forming the base member 33 with a sheet-like material having elasticity, the base member 33 can be easily attached to and detached from the mattress.

  As shown in FIG. 4, a string-like rubber member 35 is integrally provided at a portion corresponding to the four corners of the mattress 31 of the engaging portion 33 c, and the engaging portion 33 c is provided around the lower surface of the mattress 31. It is elastically engaged with the part. Thereby, the base member 33 is held immovably on the mattress 31.

  The sliding member 34 is made of, for example, a sheet-like material having at least a sliding property, such as a satin weaving fabric, a sheet made of synthetic resin fibers such as polyester, and the like. Thus, it is formed by sewing into a sheet shape having a predetermined thickness.

  Accordingly, the upper surface of the base member 33 and the lower surface of the sliding member 34 that are in contact with each other are formed on sliding surfaces 33f and 34f that can slide.

  The sliding member 34 is placed on the upper surface of the mirror portion 33 a of the base member 34 attached to the mattress 31. As shown in FIG. 2, the other end side of the upper surface of the mirror portion 33 a and the lower surface of the sliding member 34 located on the first and second leg floor portions 11 and 12 side of the floor plate body 6. At both ends in the width direction, planar fasteners 39a and 39b are provided as connecting means. In this embodiment, the planar fasteners 39a and 39b are provided over the length of about half of the longitudinal direction of the mattress 31.

  By engaging the planar fasteners 39 a and 39 b, the other end side of the sliding member 34 is connected and fixed to the base member 33. Accordingly, when the one end portion side of the mattress 31 is bent upward, the slip surface 34f of the slide member 34 is not connected to the base member 33, and the one end portion side of the mat member 31 is not connected to the slide surface 33f of the base member 33. It comes to slide.

  As shown in FIGS. 5 and 6, one end in the longitudinal direction of the base member 33 and the sliding member 34 is connected to the entire length in the width direction by a detent member 41 formed of a soft sheet-like material such as cloth. Has been.

  As shown in FIG. 5, the slip prevention member 41 has a length dimension capable of lifting one end of the slide member 34 upward by a predetermined dimension. That is, the slip prevention member 41 has a length that is in a slack state in a state where one end portion of the slip member 34 is not slid with respect to the base member 33.

  Accordingly, as shown in FIG. 6, the mattress 31 is curved so that one end portion side of the sliding member 34 is located above the upper surface of the mirror portion 33a of the base member 33 attached to the mattress 31, that is, the sliding surface 33f. The slip prevention member 41 allows the sliding member 34 to slide while being extended, and prevents one end of the sliding member 34 from shifting in the width direction of the mattress 31 when sliding. It has become.

  Since the base member 33 and the sliding member 34 are formed of a sheet-like material having lubricity as described above, when the mattress 31 is curved, the base member 33 and the sliding member 34 are One end of the sliding member 34 slides smoothly.

  In this way, the base member 33 formed of a sheet-like material having lubricity and stretchability is attached to the mattress 31 used in the wake-up type bed apparatus 1, and the mirror portion 33a of the base member 33 is attached. Similar to the base member 33, a slip member 34 made of a sheet-like material having lubricity is provided on the upper surface. And the other end part side of the said base member 33 and the sliding member 34 was connected with the planar fasteners 39a and 39b.

  Therefore, when the user U wants to raise his / her upper body, turning the back floor portion 9 of the bed apparatus 1 in the upward direction and bending one end portion of the mattress 31 upward causes the mattress 31 to The sliding surface 34f on the lower surface on the one end side of the sliding member 34 slides relative to the sliding surface 33f of the mounted base member 33. That is, the one end side of the mattress 31 where the one end side of the sliding member 34 rises moves upward.

  Therefore, when the mattress 31 is bent, the compressive force generated on the upper surface of the mattress 31 almost acts on the back surface of the user U because one end of the sliding member 34 slides with respect to the upper surface of the mattress 31. Therefore, the back surface of the user U is prevented from being compressed by the compressive force generated on the upper surface of the mattress 31.

  The base member 33 and the sliding member 34 are back-raised beddings 32 that can be attached to the mattress 31. Therefore, the mattress 31 can be easily mounted and used with respect to the existing mattress 31 used in the wake-up type bed apparatus 1, that is, the mattress 31 having a structure that cannot prevent the compressive force from being applied to the back surface of the user when raising the back. be able to.

  That is, it is possible to prevent the compressive force generated on the upper surface of the mattress 31 from being applied to the back surface of the user U when the back is raised only by attaching the base member 33 and the sliding member 34 to the mattress 31 used conventionally. Therefore, it is not necessary to replace the existing mattress, which is convenient and economical.

  In addition, the sliding member 34 and the base member 33 are made of a sheet-like material having lubricity. Therefore, when the mattress 31 is bent, the sliding member 34 slides smoothly with respect to the base member 33. This also causes the compression generated on the upper surface of the mattress 31 on the back surface of the user U when raising the back. The force can be prevented from acting.

  The total length in the width direction of one end of the sliding member 34 and one end of the base member 33 is connected to one end of the base member 33 by a displacement preventing member 41. In a state where the sliding member 34 is not displaced with respect to the base member 33, the displacement preventing member 41 is in a slack state.

  Therefore, the one end side of the sliding member 34 does not interfere with the slip prevention member 41 when the back is raised, and the sliding member 34 slides in the ascending direction. Moreover, it is prevented that the one end part shifts | deviates to the width direction of the mattress 31. FIG.

  That is, when the back is raised, one end portion side of the sliding member 34 is limited to the displacement preventing member 41 in the width direction, so that the sliding member 34 reliably slides in the upward direction with respect to the base member 33. Thereby, the function of the sliding member 34 is reliably maintained.
