Detailed Description
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
The drawings are schematic or conceptual. In the present specification and the drawings, the same elements as those described above are denoted by the same reference numerals as those in the existing drawings, and detailed description thereof is omitted as appropriate.
(first embodiment)
Fig. 1 is a schematic side view illustrating a side rail of a first embodiment.
Fig. 2 is a schematic cross-sectional view illustrating a side rail of the first embodiment.
As shown in fig. 1, the side rail 150 of the embodiment is used by being fixed to a frame 70F of a bed or the like.
As shown in fig. 2, the side rail 150 includes a resin member 10 and a rod core 60. The rod core 60 is in the resin member 10. In this example, a plurality of rod cores 60 (a first rod member 61, a second rod member 62, and the like) are provided. A plurality of rod cores 60 are in the resin member 10. For example, the rod core 60 is covered with at least a part of the resin member 10. A part of the resin member 10 is plate-shaped. By making the rod core 60 into the resin member 10, for example, it is easy to keep the side rail 150 clean. For example, the cold feeling is suppressed as compared with the case where the surface is metal or the like. Cleaning and the like become easy, and the cleanness is easily maintained. According to an embodiment, a convenient side rail can be provided.
The resin member 10 is integrally formed of, for example, resin. The resin member 10 contains, for example, at least 1 selected from the group consisting of polypropylene and polyethylene. The rod core 60 is made of metal, and contains, for example, at least 1 selected from the group consisting of iron and high-tensile steel (e.g., "high-strength steel").
As shown in fig. 1, the resin member 10 includes a shaft portion (e.g., a first projection 50A and a second projection 50B, etc.). The rod portion can be inserted into holes 70Fa, 70Fb, etc. provided in a frame 70F, etc. of the bed. Thereby, the side rail 150 can be fixed to the frame 70F. In the shaft portion (for example, the first projection 50A and the second projection 50B, etc.) of the resin member 10, at least a part of the rod-shaped core 60 is present.
The resin member 10 includes, for example, a plate-like portion. The plate-like portion of the resin member 10 includes a frame portion 10M. The lever portion (e.g., the first projection 50A and the second projection 50B, etc.) projects from the lower end of the frame portion 10M. For example, when the side rail 150 is mounted to a bed, the plate-like portion is positioned beside the user of the bed. An example of the plate-like portion of the resin member 10 will be described below.
As shown in fig. 1, the plate-like portion of the resin member 10 includes a first extending portion 11, a second extending portion 12, a first continuous portion 21, and a second continuous portion 22 in addition to the frame portion 10M. First extending portion 11, second extending portion 12, first continuous portion 21, and second continuous portion 22 are disposed above frame portion 10M. The first and second continuous portions 21 and 22 protrude from the upper end of the frame portion 10M.
The first extension 11 extends along a first extension direction De 1. The first extending portion 11 is connected to the frame portion 10M over the entire length of the first extending portion 11. The second extension portion 12 is disposed on the first extension portion 11. The second extension 12 extends along a second extension direction De 2. The second extension direction De2 is inclined with respect to the first extension direction De 1.
The first continuous portion 21 is connected seamlessly to one end 11a of the first extension portion 11 and one end 12a of the second extension portion 12. The second continuous portion 22 is seamlessly connected to the other end 11b of the first extending portion 11 and the other end 12b of the second extending portion 12. There is a gap SP1 between the first extension 11 and the second extension 12.
For example, the first continuous portion 21 extends along the direction D21. The direction D21 intersects the first extension direction De1 and the second extension direction De 2. The second continuous portion 22 extends along the direction D22. The direction D22 intersects the first extension direction De1 and the second extension direction De 2.
By the seamless connection of the first and second continuous portions 21 and 22 with the first and second extending portions 11 and 12, there is no gap at the connecting portion between these regions. For example, the side rail 150 is manufactured by integral molding. Since there is no gap in the connecting portion, cleaning, for example, becomes easy. Dirt is not easy to generate. The cleanness can be easily maintained.
Since the gap SP1 is provided between the first extension portion 11 and the second extension portion 12, the user does not easily feel a sense of pressure.
The extending direction of the first extending portion 11 is inclined with respect to the extending direction of the second extending portion 12. These extensions are not "lattice-like". This makes it less likely that the user will feel uncomfortable than in the case of the "lattice shape". It is easy to provide a feeling of reassurance to the user.
In this example, the direction D21 is inclined with respect to the direction D22. Thus, the side rail 150 is shaped further away from the "grid". This further reduces the feeling of pressure.
In this example, the resin member 10 further includes a third extending portion 13 and a third continuous portion 23. The third extending portion 13 is disposed on the second extending portion 12. The third extending portion 13 extends along a third extending direction De 3. The third extension direction De3 is inclined with respect to the first extension direction De1 and the second extension direction De 2.
The third continuous portion 23 is disposed on an extension line of the first continuous portion 21, for example. The third continuous portion 23 is seamlessly connected to the one end 12a of the second extending portion 12, the first continuous portion 21, and the one end 13a of the third extending portion 13. At least a portion of the second extension 12 is located between the first extension 11 and the third extension 13. There is a gap SP2 between the second extension 12 and the third extension 13.
Since the third continuous portion 23 is seamlessly connected to the other region, there is no gap in the connection portion between the third continuous portion 23 and the other region. Since there is no gap in the connecting portion, cleaning, for example, becomes easy. Dirt is not easy to generate. The cleanness can be easily maintained.
As shown in fig. 1, the resin member 10 includes a base region 50. The base region 50 constitutes a lower portion of the frame portion 10M. The base region 50 is fixed to the bed. The base region 50 extends along a first direction D1. The lever portion (e.g., the first projection 50A and the second projection 50B, etc.) is fixed to the base region 50. In 1 example, the first direction D1 is along the horizontal plane of the bed.
The vertical direction of the bed when the side rail 150 is fixed to the bed is the X-axis direction. The direction perpendicular to the X-axis direction is defined as the Y-axis direction. The direction perpendicular to the X-axis direction and the Y-axis direction is defined as the Z-axis direction. The Y-axis direction corresponds to the left and right direction of the bed when the side rail 150 is fixed to the bed. The Z-axis direction corresponds to the height direction of the bed when the side rail 150 is fixed to the bed.
The base region 50 is, for example, seamlessly connected to the first extension portion 11, the first continuous portion 21, and the second continuous portion 22. At least a portion of the first extension 11 is located between the base region 50 and the third extension 13. At least a portion of the second extension 12 is located between the first extension 11 and the third extension 13. For example, in the case where the base region 50 is located below, there is the first extension portion 11 above the base region 50. Above the first extension 11 there is a second extension 12. Above the second extension 12 is a third extension 13.
As shown in fig. 1, for example, a second angle θ 2 between the second extending direction De2 and the first direction D1 is greater than a first angle θ 1 between the first extending direction De1 and the first direction D1. A third angle θ 3 between the third extending direction De3 and the first direction D1 is greater than the second angle θ 2.
By using a plurality of extensions having different first to third angles θ 1 to θ 3, the summary of the back lift angle can be easily known, for example, by merely observing the relationship between the direction of these extensions and the upper surface of the bed. This is facilitated by simply knowing the back rise angle.
For example, the first angle θ 1 is 3 degrees or more and 8 degrees or less. The second angle θ 2 exceeds 8 degrees and is 15 degrees or less. For example, the third angle θ 3 exceeds 15 degrees and is 30 degrees or less. For example, the rising back angle can be more easily known by making the extending direction coincide with a practical rising back angle.
As shown in fig. 1, in this example, the side rail 150 (e.g., the resin member 10) further includes a fourth extending portion 14, a fourth continuous portion 24, and a fifth continuous portion 25.
The fourth extension 14 extends in the first direction D1. The fourth extending portion 14 is disposed on the third extending portion 13 and constitutes an upper edge portion of the side rail 150. The fourth extension 14 includes a first portion 14a, a second portion 14b, a third portion 14c, and a fourth portion 14 d. The third portion 14c is located between the first portion 14a and the second portion 14 b. The fourth portion 14d is located between the first portion 14a and the third portion 14 c.
The fourth continuous portion 24 is disposed on an extension line of the third continuous portion 23, for example. The fourth continuous portion 24 is seamlessly connected to the first portion 14a and the one end 13a of the third extending portion 13. The fifth continuous portion 25 is disposed on an extension line of the second continuous portion 22, for example. The fifth continuous portion 25 is seamlessly connected with the other end 12b and the second portion 14b of the second extension portion 12.
The other end 13b of the third extension 13 is seamlessly connected to the third portion 14 c. At least a portion of the second extension 12 is located between the first extension 11 and the fourth extension 14. At least a portion of the third extension 13 is located between the second extension 12 and the fourth portion 14 d. There is a gap SP3 between the third extension 13 and the fourth portion 14 d.
Since the fourth extending portion 14, the fourth continuous portion 24, and the fifth continuous portion 25 are seamlessly connected to other regions, there is no gap in the connecting portion between the plurality of regions. Since there is no gap in the connecting portion, cleaning, for example, becomes easy. Dirt is not easy to generate. The cleanness can be easily maintained.
The direction from the first portion 14a toward the second portion 14b corresponds to the extending direction of the fourth extending portion 14 (fourth extending direction De 4). For example, the fourth extending direction De4 is along the first direction D1. For example, an angle between the fourth extending direction De4 and the first direction D1 is smaller than the first angle θ 1. The angle between the fourth extending direction De4 and the first direction D1 is, for example, less than 3 degrees.
The fourth direction of extension De4 is along the first direction D1 of the base area 50, whereby the upper portion of the side rail 150 is along the horizontal plane. The user of the bed is more convenient by easily supporting his body on the upper portion of the side rail 150.
As shown in fig. 1, in this example, the direction from the first continuous portion 21 to the third continuous portion 23 is along the direction from the third continuous portion 23 to the fourth continuous portion 24. These directions are for example along direction D21. The direction from the second continuation 22 to the fourth continuation 24 is along the direction D22. The direction from the first continuous portion 21 to the third continuous portion 23 (the direction along D21) is inclined with respect to the direction from the second continuous portion 22 to the fourth continuous portion 24 (the direction along D22). By using such an oblique angle, the side rail 150 is shaped more away from the "grid". The oppressive feeling can be further reduced.
As shown in fig. 1, in this example, the side rail 150 (e.g., the resin member 10) further includes a fifth extending portion 15, a sixth extending portion 16, a sixth continuous portion 26, and a seventh continuous portion 27. The fifth extending portion 15 extends along a fifth extending direction De 5. The sixth extending portion 16 extends along a sixth extending direction De 6. The sixth continuous portion 26 and the seventh continuous portion 27 extend, for example, in the Z direction, and constitute one side edge portion of the side rail 150.
The sixth continuous portion 26 is seamlessly connected to one end 15a of the fifth extending portion 15 and one end 16a of the sixth extending portion 16.
The fourth extension 14 includes a fifth portion 14e and a sixth portion 14 f. Between the second portion 14b and the fifth portion 14e there is a first portion 14 a. Between the first portion 14a and the fifth portion 14e there is a sixth portion 14 f. The seventh continuous portion 27 is seamlessly connected to the sixth continuous portion 26, the one end 16a of the sixth extending portion 16, and the fifth portion 14 e.
The other end 15b of the fifth extending portion 15 is seamlessly connected to the first continuous portion 21. The other end 16b of the sixth extending portion 16 is seamlessly connected to the third continuous portion 23. A gap SP4 is provided between the fifth extension 15 and the sixth extension 16. There is a gap SP5 between the sixth extension 16 and the sixth portion 14 f. Since the plurality of regions are seamlessly connected to each other, there is no gap in the connecting portion between the plurality of regions. Since there is no gap in the connecting portion, cleaning, for example, becomes easy. Dirt is not easy to generate. The cleanness can be easily maintained.
As shown in fig. 1, in this example, the side rail 150 (e.g., the resin member 10) further includes a seventh extending portion 17, an eighth extending portion 18, an eighth continuous portion 28, and a ninth continuous portion 29. The seventh extending portion 17 extends along a seventh extending direction De 7. The eighth extending portion 18 extends along an eighth extending direction De 8. The eighth continuous portion 28 and the ninth continuous portion 29 extend, for example, in the Z direction, and constitute the other side edge portion of the side rail 150.
The fourth extension 14 includes a seventh portion 14g and an eighth portion 14 h. Between the seventh portion 14g and the first portion 14a there is a second portion 14 b. Between the seventh portion 14g and the second portion 14b there is an eighth portion 14 h.
One end 17a of the seventh extending portion 17 is seamlessly connected to the second continuous portion 22. One end 18a of the eighth extending portion 18 is seamlessly connected to the fifth continuous portion 25. The eighth continuous portion 28 is connected seamlessly to the other end 17b of the seventh extending portion 17 and the other end 17b of the eighth extending portion 18. The ninth continuous portion 29 is seamlessly connected to the eighth continuous portion 28, the other end 18b of the eighth extending portion 18, and the seventh portion 14 g. A gap SP6 is provided between the seventh extending portion 17 and the eighth extending portion 18. There is a gap SP7 between the eighth extension 18 and the eighth portion 14 h. Since the plurality of regions are seamlessly connected to each other, there is no gap in the connecting portion between the plurality of regions. Since there is no gap in the connecting portion, cleaning, for example, becomes easy. Dirt is not easy to generate. The cleanness can be easily maintained.
In this way, in the frame portion 10M of the resin member 10, gaps SP1 to SP7 are formed that penetrate the side rails 150 in the thickness direction (Y direction). The gap SP1 is a substantially rectangular region surrounded by the first continuous portion 21, the second continuous portion 22, the first extending portion 11, and the second extending portion 12. Gap SP2 is a substantially pentagonal region surrounded by third continuous portion 23, fifth continuous portion 25, second extending portion 12, third extending portion 13, and fourth extending portion 14. The gap SP3 is a substantially triangular region surrounded by the fourth continuous portion 24, the first extending portion 13, and the fourth extending portion 14.
The gap SP4 is a substantially rectangular region surrounded by the first continuous portion 21, the sixth continuous portion 26, the fifth extending portion 15, and the sixth extending portion 16. The gap SP5 is a substantially rectangular region surrounded by the fourth continuous portion 24, the seventh continuous portion 27, the sixth extending portion 16, and the fourth extending portion 14. The gap SP6 is a substantially rectangular region surrounded by the second continuous portion 22, the eighth continuous portion 28, the seventh extending portion 17, and the eighth extending portion 18. The gap SP7 is a substantially rectangular region surrounded by the fifth continuous portion 25, the ninth continuous portion 29, the eighth extending portion 18, and the fourth extending portion 14.
As shown in fig. 1, in this example, the side rail 150 (e.g., the resin component 10) also includes a first intermediate region 31. The first intermediate region 31 is disposed between the base region 50 and the first extension 11. The first intermediate region 31 is seamlessly connected with the base region 50 and the first extension 11.
In this example, the side rail 150 (e.g., the resin component 10) also includes the second intermediate region 32. The second intermediate region 32 is disposed between the base region 50 and the fifth extension 15. The second intermediate region 32 is seamlessly connected with the base region 50 and the fifth extension 15.
In this example, the side rail 150 (e.g., the resin component 10) also includes a third intermediate area 33. The third intermediate area 33 is disposed between the base area 50 and the seventh extension 17. The third intermediate region 33 is seamlessly connected with the base region 50 and the seventh extension 17.
By providing the first intermediate region 31, there is no gap between the base region 50 and the first extension 11. By providing the second intermediate region 32, there is no gap between the base region 50 and the fifth extension 15. By providing the third intermediate region 33, there is no gap between the base region 50 and the seventh extension 17.
The first to third intermediate regions 31 to 33 correspond to lower portions of the side rails 150. Since there is no gap between the base region 50 and the first extending portion 11, between the base region 50 and the fifth extending portion 15, and between the base region 50 and the seventh extending portion 17, it is possible to suppress the article from falling down therebetween. More convenient side rails can be provided.
The surfaces of the first to eighth extending portions 11 to 18, the first to ninth continuous portions 21 to 29, the base region 50, and the first to third intermediate regions 31 to 33 include, for example, resin. The cold feeling is suppressed as compared with the case where the surface is made of metal or the like. Cleaning and the like become easy, and the cleanness is easily maintained.
As described above, the side rail 150 is provided with the first rod member 61 and the second rod member 62 as the rod core 60. The first rod member 61 and the second rod member 62 are made of metal, and have a tubular shape, for example. As shown in fig. 2, the rod core 60 includes portions (reinforcing portions) corresponding to the shaft portions (e.g., the first protruding portion 50A and the second protruding portion 50B, etc.). The thickness of the portion (reinforcing portion) of the rod core 60 may be thinner than the thickness of the other portion of the rod core 60.
The lower portion of the first lever member 61 is disposed in the first protrusion 50A and serves as a first reinforcing portion 61 a. The first reinforcement portion 61a reinforces the first protrusion 50A. The upper portion (first upper portion 61b) of the first lever member 61 is disposed in the first continuous portion 21, the third continuous portion 23, and the fourth continuous portion 24. The intermediate portion (first intermediate portion 61c) of the first lever member 61 is a portion connecting the first reinforcing portion 61a and the first upper portion 61 b. The first intermediate portion 61c is disposed in the frame portion 10M. The first lever member 61 is bent in the frame portion 10M near the boundary between the first middle portion 61c and the first upper portion 61 b.
The lower portion of the second lever member 62 is disposed in the second protrusion 50B and serves as a second reinforcing portion 62 a. The second reinforcement portion 62a reinforces the second protruding portion 50B. The upper portion (second upper portion 62b) of the second lever member 62 is disposed in the second continuous portion 22 and the fifth continuous portion 25. The middle portion (second middle portion 62c) of the second lever member 62 is a portion connecting the second reinforcing portion 62a and the second upper portion 62 b. The second intermediate portion 62c is disposed in the frame portion 10M. The second lever member 62 is, for example, straight tubular in shape.
The first reinforcing portion 61a and the second reinforcing portion 62a are parallel to each other, for example, extend in the Z direction. The first intermediate portion 61c and the second intermediate portion 62c are parallel to each other, for example, extend in the Z direction. The first upper portion 61b and the second upper portion 62b are inclined so as to be separated from each other as they are distant from the frame portion 10M.
Fig. 3 is a schematic side view illustrating a side rail of the first embodiment.
As shown in fig. 3, a direction perpendicular to the first direction along a plane including the first extending direction De1 and the second extending direction De2 is set as a second direction D2.
As shown in fig. 3, for example, a distance Hb1 between the seating region 50 and the other end 11b of the first extension portion 11 in the second direction D2 is longer than a distance Ha1 between the seating region 50 and the one end 11a of the first extension portion 11 in the second direction D2. For example, the other end 11b of the first extending portion 11 is located above the one end 11a of the first extending portion 11.
For example, a distance Hb2 along the second direction D2 between the seating region 50 and the other end 12b of the second extension portion 12 is longer than a distance Ha2 along the second direction D2 between the seating region 50 and the one end 12a of the second extension portion 12. For example, the other end 12b of the second extension portion 12 is located above the one end 12a of the second extension portion 12.
For example, a distance Hb3 between the seating region 50 and the other end 13b of the third extension 13 along the second direction D2 is longer than a distance Ha3 between the seating region 50 and the one end 13a of the third extension 13 along the second direction D2. For example, the other end 13b of the third extending portion 13 is located above the one end 13a of the third extending portion 13.
For example, the other end of the extension is placed on the head side of the bed. One end of the extension part is placed at the foot side of the bed. For example, the extension extends along the raised back pallet.
Fig. 4 is a schematic side view illustrating a side rail of the first embodiment.
For example, a distance Hb5 between the seating region 50 and the other end 15b of the fifth extending portion 15 along the second direction D2 is shorter than a distance Ha5 between the seating region 50 and the one end 15a of the fifth extending portion 15 along the second direction D2. For example, the other end 15b of the fifth extending portion 15 is located below the one end 15a of the fifth extending portion 15.
For example, a distance Hb6 between the seating region 50 and the other end 16b of the sixth extending portion 16 along the second direction D2 is shorter than a distance Ha6 between the seating region 50 and the one end 16a of the sixth extending portion 16 along the second direction D2. For example, the other end 16b of the sixth extending portion 16 is located below the one end 16a of the sixth extending portion 16.
For example, a distance Hb7 between the seating region 50 and the other end 17b of the seventh extending portion 17 along the second direction D2 is shorter than a distance Ha7 between the seating region 50 and the one end 17a of the seventh extending portion 17 along the second direction D2. For example, the other end 17b of the seventh extending portion 17 is located below the one end 17a of the seventh extending portion 17.
For example, a distance Hb8 between the seating region 50 and the other end 18b of the eighth extending portion 18 along the second direction D2 is shorter than a distance Ha8 between the seating region 50 and the one end 18a of the eighth extending portion 18 along the second direction D2. For example, the other end 18b of the eighth extending portion 18 is located below the one end 18a of the eighth extending portion 18.
For example, the direction of inclination of the fifth and sixth extensions 15 and 16 is opposite to the direction of inclination of the first extension 11. For example, the directions of the inclinations of the seventh extension 17 and the eighth extension 18 are opposite to the direction of the inclination of the first extension 11. By such a tilt, the side rail 150 is shaped more away from the "grid". The oppressive feeling can be further suppressed.
In the embodiment, for example, the outline of the angle of inclination of the knee brace may be grasped by the inclination of the fifth extending portion 15 and the sixth extending portion 16.
Fig. 5(a) to 5(d) are schematic cross-sectional views illustrating a side rail of the first embodiment.
Fig. 5(a) is a sectional view taken along line a1-a2 of fig. 3. FIG. 5(B) is a sectional view taken along line B1-B2 of FIG. 3. FIG. 5(C) is a sectional view taken along line C1-C2 of FIG. 3. FIG. 5(D) is a sectional view taken along line D1-D2 of FIG. 3.
As shown in fig. 5(a), for example, the thickness of the third intermediate region 33 is thinner than the thickness of the base region 50 and thinner than the thickness of the seventh extending portion 17. As shown in fig. 5(c), for example, the thickness of the first intermediate region 31 is thinner than the thickness of the base region 50 and thinner than the thickness of the first extension 11. As shown in fig. 5(d), for example, the thickness of the second intermediate region 32 is thinner than the thickness of the base region 50 and thinner than the thickness of the fifth extension 15. These thicknesses correspond to the length along the Y-axis direction. The first to third intermediate regions 31 to 33 are thin, and thus, for example, the side rail 150 is light while maintaining high strength.
As shown in fig. 4, the base region 50 includes a first end portion 50a, a second end portion 50b, a first intermediate portion 51, a second intermediate portion 52, and a third intermediate portion 53. The direction from the first end 50a to the second end 50b is along a first direction D1.
The first intermediate portion 51 is located between the first end portion 50a and the second end portion 50b in the first direction D1. The second intermediate portion 52 is located between the first intermediate portion 51 and the second end portion 50b in the first direction D1. The third intermediate portion 52 is located between the first intermediate portion 51 and the second intermediate portion 52 in the first direction D1. The first protruding portion 50A is disposed between the first intermediate portion 51 and the third intermediate portion 53. The second protruding portion 50B is disposed between the second intermediate portion 52 and the third intermediate portion 53.
As shown in fig. 4, a direction perpendicular to the first extending direction De1 and the first direction D1 is defined as a third direction D3. The third direction D3 is, for example, the Y-axis direction.
Fig. 6 is a schematic bottom view illustrating the side rail of the first embodiment.
As shown in fig. 6, the thickness t50a of the first end portion 50a along the third direction D3 is thicker than the thickness t51 of the first middle portion 51 along the third direction D3. The thickness t50b of the second end portion 50b along the third direction D3 is thicker than the thickness t52 of the second middle portion 52 along the third direction D3.
By increasing the thickness of the end portion, for example, high strength can be obtained. For example, a portion which is easily contaminated becomes clear, and cleaning and the like become easier.
As already explained, the side rail 150 includes, for example, a first projection 50A and a second projection 50B (see fig. 4). As shown in fig. 4, a first projection 50A and a second projection 50B are connected to the base region 50. The first projection 50A and the second projection 50B extend along the crossing direction Dx. The crossing direction Dx crosses the first direction D1 along a plane (X-Z plane) including the first extending direction De1 and the third extending direction De 3.
As shown in fig. 1, the first protrusion 50A can be inserted into a hole 70Fa provided in a bed (e.g., a frame 70F). The second projection 50B can be inserted into a hole 70Fb provided in the bed (for example, the frame 70F).
Fig. 7(a) and 7(b) are schematic bottom views illustrating the side rail of the first embodiment.
As shown in fig. 7(b), the first projecting portion 50A includes a projecting portion 50Ap projecting in a direction intersecting the intersecting direction Dx. As shown in fig. 7(a), the second projecting portion 50B includes a projecting portion 50Bp projecting in a direction intersecting the intersecting direction Dx. By providing such a protrusion, the side rail 150 is stably fixed to the hole.
Fig. 8 is a schematic bottom view illustrating the side rail of the first embodiment.
As shown in fig. 8, the cross-sectional shape of the first protruding portion 50A (or the second protruding portion 50B) can be variously modified. For example, the deformation can be easily performed by changing a part of the mold.
(second embodiment)
Fig. 9 is a schematic perspective view illustrating a bed device of a second embodiment.
As shown in fig. 9, the bed arrangement 310 of the embodiment includes a frame 70F. The frame 70F is supported by, for example, a base frame 70 BF. The first and second protruding portions 50A and 50B of the side rail 150 of the first embodiment are inserted into the holes 70Fa and 70Fb, etc. provided in the frame 70F. In the bed device 310, the back splint 70a, the knee splint 70c, the foot splint 70d, the head board 78H, the foot board 78F, and the like may be provided on the frame 70F. According to the second embodiment, a convenient bed device can be provided.
Fig. 10(a), 10(b), and 11 are schematic views illustrating a bed device according to a second embodiment.
Fig. 10(a) is a perspective view. Fig. 10(b) is a side view. Fig. 11 is a perspective view.
As shown in fig. 10(a) and 10(b), the bed device 320 of the embodiment includes a frame 70F. The first projection 50A and the second projection 50B are inserted into holes 70Fa, 70Fb, and the like provided in the frame 70F.
As shown in fig. 10(b), the entire frame 70F may be inclined. As shown in fig. 11, the height of the frame 70F is variable.
Fig. 12 to 14 are schematic side views illustrating a bed device of a second embodiment.
As shown in fig. 12 to 14, a mattress 70M is placed on the back plate 70a or the like.
As shown in fig. 12, the inclination angle of the back splint 70a is about 5 ° in 1 state. At this time, the inclination angle of the mattress 70M is also about 5 °. In this state, the first extension 11 follows the inclination. For example, the first extension 11 is along the upper surface of the mattress 70M.
As shown in fig. 13, the inclination angle of the back splint 70a is about 10 ° in 1 state. At this time, the inclination angle of the mattress 70M is also about 10 °. In this state, the second extension portion 12 follows the inclination. For example, the second extension 12 is along the upper surface of the mattress 70M.
As shown in fig. 14, the inclination angle of the back splint 70a is about 20 ° in 1 state. At this time, the inclination angle of the mattress 70M is also about 20 °. In this state, the third extension 13 follows the inclination. For example, the third extension 13 is along the upper surface of the mattress 70M.
According to the embodiment, for example, a side rail having a shape with a high degree of freedom by resin molding can be obtained. For example, no gaps are created between the regions, providing an integrally molded construction. This facilitates wiping, for example. For example, cleaning becomes easy.
According to the embodiment, for example, the ratio of the flat surface portion can be increased as compared with a configuration in which a circular tube is combined. In an embodiment, for example, the side rails are covered with a resin material. This can reduce the cold feeling as compared with the case where steel is exposed on the surface.
In the embodiment, for example, the extending directions of the extending portion and the continuous portion are inclined to each other. For example, the gaps SP1 to SP7 are not lattice-shaped. For example, the feeling of oppression is suppressed as compared with the case of the lattice-like shape.
According to the embodiment, the weight of the coating can be about 80% of the conventional coating. In the embodiment, it is convenient to know the outline of the angle of the back rising from the shape of the extension portion.
For example, the side rails may be provided with projections on the stems thereof. The side rails can be stably fixed to the frame 70F of the bed or the like.
By making the end of the side rail thicker than other parts, for example, parts that are prone to contamination become apparent. By providing the intermediate regions (for example, the first to third intermediate regions 31 to 33), the protection member is provided to such an extent that visibility is not deteriorated. For example, the falling of articles from the bed can be suppressed.
For example, by changing a part of the members used in the manufacturing, it is possible to easily manufacture the "side rail for home use" or the "side rail for hospital and facility use" by using the same mold.
