Description

  The present invention relates to a backrest structure using a stepped floor provided in, for example, an indoor space of a house.

  Conventionally, various types of houses have been proposed in which the floor surface of a living room or the like is partially or entirely lowered to produce a calm recessed space surrounded by a stepped portion (for example, Patent Document 1). reference).

  In such a recessed space, the user can relax in various postures by using the floor step portion as a stool or a backrest. However, when the floor step portion is used as a backrest, there is a problem that the back contact with the back is bad and it cannot be relaxed sufficiently.

  That is, as shown in FIG. 6, the floor step portion 30 generally has a structure in which a substantially vertical step surface 33 is interposed between a substantially horizontal upper step surface 31 and a substantially horizontal lower step surface 32. When such a floor step portion 30 is used as a backrest, the user leans his back against the step surface 33 while sitting on the lower step surface 32. At this time, the user's back is inclined obliquely, but since the step surface 33 is substantially vertical, the corner portion between the upper step surface 31 and the step surface 33 is likely to hit the back locally. When I sat for a long time, my back hurt.

  Therefore, when the floor step portion is used as a backrest, it is routinely performed to sit with a cushioning material sandwiched between the back and the step surface. Moreover, the structure which stuck the cushion material of the shape according to a level | step difference surface to a level | step difference surface is also seen (for example, refer patent document 2).

  However, when the cushioning material is sandwiched between the back and the stepped surface, there is a problem that depending on the shape and size of the cushioning material, an uncomfortable feeling may occur and the person cannot sit in a relaxed state. On the other hand, when attaching cushioning material to a stepped surface, for example, when installing furniture etc. along the stepped surface, the cushioning material gets in the way, or as the cushioning material deteriorates, it is troublesome to replace it. There was a problem that work was necessary.

  An object of the present invention is to provide a backrest structure that can solve the above problems and can comfortably use a floor step portion as a backrest.

  In order to solve the above-mentioned problems, the backrest structure of the present invention has a structure in which a step surface 4 is interposed between an upper step surface 2 and a lower step surface 3, and the upper step surface 2 and the step surface 4 A horizontally long decorative material 5 is attached to a corner portion between the stepped surface 4 and the front surface of the stepped surface 4 so as to protrude forward. The decorative material 5 is inclined so that the amount of forward protrusion gradually increases toward the lower side. It is characterized in that it has a backrest finding surface 7c.

  Further, a cushion material 9 is detachably mounted between the decorative material 5 and the lower step surface 3, and the cushion material 9 is a backrest that is continuous with the seating surface 7 c for the backrest of the decorative material 5 when the cushion material 9 is mounted. It has a surface 9c.

  Furthermore, the height dimension H1 from the upper step surface 2 to the lower step surface 3 is set to 300 to 400 mm.

  In addition, the backrest finding surface 7c of the decorative material 5 has an inclination angle α with respect to the horizontal plane G of 75 to 80 degrees and a vertical height dimension H2 of 70 to 100 mm.

  Furthermore, the upper surfaces 6a and 7a of the decorative material 5 are arranged flush with the upper step surface 2, and the corner portion between the upper surface 7a of the decorative material 5 and the seating surface 7c for backrest is rounded. A notch portion 8 for preventing slipping is formed at the corner portion.

  In the backrest structure of the present invention, when the floor step portion is used as the backrest, the slanted backrest face of the cosmetic material hits the slanted back of the user seated on the lower step surface. Even when sitting for a relatively long time, the back does not easily hurt, and the floor step can be comfortably used as a backrest.

  In particular, the height from the upper step surface to the lower step surface in the stepped portion of the floor is set to 300 to 400 mm suitable for the backrest, and the inclination angle with respect to the horizontal surface of the seating back surface for the decorative material is the same as the backrest of a general chair Even if the weight is sufficiently applied to the seating surface for the backrest (the back), the height dimension in the vertical direction of the seating surface for the seatback of the cosmetic material is set to 70 to 100 mm which is relatively long. Even if it is pressed strongly against the seating surface for the backrest), the back does not hurt and the comfort level can be further enhanced.

  In addition, a cushioning material is attached between the decorative material and the lower surface, and the back surface of the cushioning material is made continuous with the back surface of the decorative material so that the user's back does not feel uncomfortable. The seating surface for the backrest and the backrest surface will naturally support a wide range, and since the cushioning material is soft and elastic, the sitting comfort as the backrest can be further improved. .

  Moreover, since the cushioning material is removable, for example, when installing furniture so as to be along a stepped surface, the cushioning material becomes an obstacle, and the cushioning material needs to be troublesome to replace it. There will be no inconvenience.

  In addition, by making the corner portion between the upper surface of the decorative material and the finding surface for the backrest round, it is possible to further improve the contact of the finding surface for the backrest with the back. In this case, the foot placed on the corner portion becomes slippery when the floor step portion is raised and lowered, but the corner portion is provided with a notch for preventing slipping, which hinders safety during raising and lowering. There is nothing.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The backrest structure using the floor step portion according to one embodiment of the present invention produces a recessed space surrounded by the floor step portion, for example, by partially or entirely lowering the floor surface of a living room or dining room. It is applied in the house.

  In this backrest structure, as shown in FIG. 1 and FIG. 2, an upper step surface in a floor step portion 1 in which a substantially vertical step surface 4 is interposed between a substantially horizontal upper step surface 2 and a substantially horizontal lower step surface 3. A horizontally long wooden decorative material 5 having a function as a saddle material or parting material is attached to a corner portion between 2 and the stepped surface 4.

  In FIG. 2, 10 is soil concrete, 11 and 12 are bundles erected on the soil concrete 10, 13 is a steel plate attached on the bundle material 11, and 14 is mounted on a steel plate 13. Joists, 15 is an upper flooring laid on the joists 14, 16 is a lower flooring laid on the bundle 12, 12 is a steel base material, 18 is a surface decorative board attached to the front surface of the steel base material 17, Reference numeral 19 denotes a base material that receives the decorative material 5.

  The upper surface 2 is constituted by, for example, the upper surface of the upper flooring 15, the lower step surface 3 is constituted by, for example, the upper surface of the lower flooring 16, and the step surface 4 is constituted by, for example, the front surface of the surface decorative board 18. And the height dimension (step dimension) H1 of the perpendicular direction from the upper stage surface 2 to the lower stage surface 3 is set to 300-400 mm (preferably 360 mm), for example. By setting the height dimension H1 in this way, it is possible to make a recessed space with a calm atmosphere, and it is also suitable for using the floor step portion 1 as a stool or a backrest.

  As shown in FIGS. 2 and 3, the decorative material 5 includes a horizontal piece 6 that covers the end surface of the upper flooring 15, and a hanging piece 7 that hangs down from the front end of the horizontal piece 6, and has a substantially L-shaped cross section. It is formed in a shape. The decorative material 5 is fixed to the base material 19 so that the hanging piece 7 protrudes forward (in the direction indicated by the white arrow in FIG. 1) from the step surface 4. (The substantially horizontal upper surfaces 6 a and 7 a of the horizontal piece 6 and the hanging piece 7) are arranged flush with the upper surface 2, and the substantially horizontal lower surface 7 b of the hanging piece 7 is a predetermined distance from the lower surface 3. It is arranged almost parallel with a gap.

  The backrest finding surface (front surface) 7c that connects the upper surface 7a and the lower surface 7b of the hanging piece 7 is an inclined surface that is inclined so that the amount of protrusion to the front gradually increases as it goes downward. As shown in FIG. 3, the seating surface 7 c for the backrest has an inclination angle α with respect to the horizontal plane G, for example, 75 to 80 degrees (preferably 78 degrees). The height dimension H2 in the direction is, for example, 70 to 100 mm (preferably 83 mm).

  Further, the corner portion between the upper surface 7a and the finding surface 7c and the corner portion between the lower surface 7b and the finding surface 7c in the hanging piece 7 are formed in a rounded curved shape by being subjected to R processing. Further, at the corner portion between the upper surface 7a and the finding surface 7c, a groove-shaped notch portion 8 for preventing slipping is formed along the lateral direction.

  When the floor step portion 1 having such a decorative material 5 attached is used as a backrest, as shown in FIG. 4, a hanging piece on the decorative material 5 is placed on the back of the user who is seated on the lower surface 3 and is inclined obliquely. No. 7 seating surface 7c for backrest hits.

  The seating surface 7c for the backrest is located near the upper end of the stepped surface 4 in the floor stepped portion 1 set to a stepped size suitable for the backrest as described above, and has the same inclination angle as the backrest of a general chair α, the height H2 is relatively long, and the upper end and the lower end are rounded, so even if the weight is sufficiently applied to the seating surface 7c for the backrest (the back is the backrest). Even if it is strongly pressed against the locating surface 7c), the back does not hurt and the floor step portion 1 can be comfortably used as a backrest.

  Moreover, in this floor level | step-difference part 1, in order to make sitting comfort as a backrest still more favorable, as shown in FIG.1 and FIG.2, the cushioning material 9 can be used together. The cushion material 9 has a substantially triangular cross section, and is detachably mounted so as to fit between the lower surface 7 b of the hanging piece 7 and the lower step surface 3 of the decorative material 5.

  The cushion material 9 includes a substantially vertical rear surface 9a that is superimposed on the stepped surface 4 when worn, a substantially horizontal lower surface 9b that is placed on the lower step surface 3 when worn, and a backrest finding surface of the hanging piece 7 on the decorative material 5 when worn. 7c has a backrest surface (front surface) 9c continuous with the backrest surface 9c. The backrest surface 9c is curved so as to bulge forward. The cushion material 9 can be removed from the floor step portion 1 and used alone as a pillow or the like.

  In this way, the cushioning material 9 is attached to the lower side of the decorative material 5, and the backrest surface 9 c of the cushioning material 9 is made to be continuous with the backrest-facing surface 7 c of the hanging piece 7 in the decorative material 5. When using 1 as a backrest, as shown in FIG. 4, the back of the user sitting on the lower surface 3 is naturally wide by the seating surface 7 c for backrest and the backrest surface 9 c without causing a sense of incongruity. In addition, since the cushion material 9 is soft and elastic, the sitting comfort as a backrest can be further improved.

  The embodiment of the present invention has been described above. However, the present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the present invention.

  For example, as shown in FIG. 5, in the floor step portion 1 provided at the window, in the corner portion between the upper step surface 2 and the step surface 4 constituted by the upper surface of the window base (window lower frame) 20, A horizontally long wooden decorative material 5 may be attached.

  Further, the decorative material 5 is not limited to wood, and may be made of synthetic resin or metal. Furthermore, the decorative material 5 is not limited to the one in which the horizontal piece 6 and the hanging piece 7 are integrally molded, and may be composed of only the hanging piece 7 that is separate from the horizontal piece 6. Furthermore, the cushion material 9 is not necessarily used together.
