Description

  This invention relates to a bed frame for placing a mattress to form a bed.

In general, when a human is sleeping, the posture (sleeping posture) is ideal if the posture is such that the S-shaped line of the spine is close to a natural standing state, which reduces the burden on the body.
Also, since the human body has irregularities, the pressure (body pressure) that the body receives from the flat surface in a state lying on the flat surface is large at the convex part and small at the concave part, and there is a local difference. Arise. At this time, blood vessels are compressed in a portion where body pressure is high, blood flow is deteriorated, and a burden on the body is generated. Therefore, in order to reduce the burden on the body, it is necessary to avoid local concentration of body pressure, that is, to distribute body pressure.

  In this regard, conventional bed frames generally use a slat-like plate material with a flat upper surface as a floor portion on which the mattress is placed. However, in such a bed frame, as described above, The sleeping posture and dispersion of body pressure are not considered.

  On the other hand, there has been a bed frame that can improve sleeping posture and disperse body pressure by using a leaf spring on the floor of the bed as in the idea described in Japanese Patent Laid-Open No. 6-189839. Yes.

According to this device, when a mattress is placed on a floor plate made of a leaf spring, and the user lies on the mattress, the leaf spring is appropriately elastically deformed (body pressure is large) according to the body pressure of the user. However, since the amount of deformation is large and the amount of deformation is small when the body pressure is small, the body pressure applied to the user can be dispersed and supported.
JP-A-6-189839

On the other hand, in order to obtain a comfortable sleep, in addition to the above-described sleeping posture and body pressure dispersion, obtaining a comfortable sleeping feeling is also an important factor. It is said that the feeling of support of the waist is greatly influenced to this sleeping comfort, and what has been proposed to obtain the desired sleeping comfort by adjusting the hardness of the leaf spring of the bed frame floor board.
Product details page of “Wooden bed frame / single / tamo / natural” (product name) at “MUJI Net Store”, [online], February 18, 2014 search, Internet (URL: http) : //www.muji.net/store/cmdty/detail/4934761331065? searchno = 2)

However, in this device, there is a problem that it takes time to adjust the hardness of the leaf springs, and the floor plate is entirely composed of leaf springs, so that the structure is complicated and the manufacturing cost is high.
Moreover, since all the floor boards are composed of leaf springs, there is also a problem of lack of stability when the mattress is placed.

  It is an object of the present invention to obtain a bed frame that can increase the support force of the waist and improve the sleeping comfort with a floor board having a simple structure.

  The bed frame of the present invention includes left and right frames and a floor portion on which the mattress is placed, and the floor portion corresponds to the position from the head to the back of the user who is supine on the mattress to be placed. , A lumbar floor portion corresponding to the position of the waist, and a leg floor portion corresponding to the position of the leg, and the lumbar floor portion is configured by spanning leaf springs curved in a convex arc shape over the left and right frames. The back floor portion and the leg floor portion have a flat upper surface using a rigid material.

For example, a wood spring may be used as the leaf spring, but the plate spring may be made of a metal or a synthetic resin as long as it is a plate-like elastic material curved in a convex arc shape. .
The back floor portion and the leg floor portion may be formed of a rigid material that is not elastically deformed and has a flat upper surface. Or using a wire or the like to form a mesh.
Here, “the upper surface is flat” means that there is no large unevenness on the upper surface side of the back floor portion and the leg floor portion serving as the mattress mounting surface, and the entire surface is flat.

The bed frame according to claim 2 includes left and right frames and a floor portion on which the mattress is placed, and the floor portion corresponds to a position from the head to the back of the user who is supine on the mattress to be placed. A floor portion, a waist floor portion corresponding to the position of the waist, and a leg floor portion corresponding to the position of the legs. The waist floor portion is provided with an intermediate receiving portion between the left and right frames. A plate spring curved in a convex arc shape is stretched over the left and right frames from a portion, and the back floor portion and the leg floor portion are configured with a flat upper surface using a rigid material.
It is conceivable that the intermediate receiving portion is provided by providing a vertical beam parallel to the left and right frames at an intermediate position between the left and right frames in the waist floor portion.

  In the bed frame according to a third aspect of the invention, the waist floor portion is configured by arranging a plurality of leaf springs in parallel.

  According to a fourth aspect of the present invention, in the invention of the third aspect, the leaf spring is configured by providing a gap between adjacent leaf springs.

  According to this device, the floor portion on which the mattress is placed includes a back floor portion, a lumbar floor portion, and a leg floor portion, and the lumbar floor portion spans the left and right frames with leaf springs curved in a convex arc shape. Since the back floor and the leg floor are made of a rigid material and the upper surface is flat, the mattress is elastically supported by a leaf spring only on the waist floor in the floor where the mattress is placed. Become. And since the leaf | plate spring which comprises a lumbar floor part is curving in convex arc shape, this is supported elastically so that the unevenness | corrugation of the user's lumbar part (part from the buttocks to the lumbar vertebrae) who lies on the mattress may be supported. be able to. Thereby, the support force with respect to a user's waist | hip | lumbar part can be heightened, ensuring the stability at the time of mattress mounting.

  According to the invention of claim 2, the waist floor portion is provided with an intermediate receiving portion between the left and right frames, and the leaf springs curved in a convex arc shape from the intermediate receiving portion toward the left and right frames, respectively, It can also accommodate a bed frame with a width that is more than double size.

  According to the invention of claim 3, since the plurality of leaf springs are elastically deformed in accordance with the heavy pressure applied to each leaf spring, it is possible to cope with a subtle difference in weighted pressure and to further improve the sleeping comfort.

  According to the fourth aspect of the present invention, since the leaf spring is disposed with a gap between the adjacent leaf springs, the leaf spring is excellent in air permeability and the sleeping comfort can be further improved.

1 to 5 are views showing an outline of a first embodiment of the bed frame of the present invention.
The bed frame 1 is configured by arranging a floor portion 3 inside an outer frame 2 composed of left and right frames 21 and 22 and front and rear frames 23 and 24.

  The floor 3 includes a back floor 31 corresponding to the position from the head to the back of the user who is supine on the mattress to be placed, a waist floor 32 corresponding to the position of the waist, and legs corresponding to the positions of the legs. And a floor portion 33.

  The back floor portion 31 and the leg floor portion 33 are formed as a flat plate member in which steel wires are assembled in a mesh shape, and the back floor portion 31 and the leg floor portion 33 are both flat surfaces as a whole on the upper side. It is comprised so that it may become. And the back floor part 31 and the leg floor part 33 are arrange | positioned inside the outer frame 2 by mounting on the some horizontal rail 25 spanned between the left-right frames 21 and 22. As shown in FIG. .

The waist floor portion 32 is configured by arranging five wooden leaf springs 4 curved in a convex arc shape at equal intervals and spanning the left and right frames 21 and 22.
Rubber fasteners 51 and 52 are attached to both ends of the leaf spring 4, and a protrusion 5 a is provided below the fasteners 51 and 52.
On the other hand, receiving portions 211 and 221 for supporting the end portions of the leaf spring 4 are provided inside the left and right frames 21 and 22, respectively, and mounting holes 211b and 221b are formed in the receiving portions 211 and 221, respectively. Yes.
The leaf spring 4 is attached to the left and right frames 21 and 22 by being fitted into and fixed to the attachment holes 211b and 221b of the receiving portions 211 and 221 respectively.

The curvature of the leaf spring 4 is such that the center portion slightly protrudes from the upper surfaces of the back floor portion 31 and the leg floor portion 33 when the mattress is not placed over the left and right frames 21 and 22 (see FIG. 2 and 3).
In the figure, reference numeral 6 is a leg of the bed frame, and 7 is a reinforcing frame.

FIG. 5 is a conceptual diagram showing a state where the mattress M is placed on the bed frame 1 according to the first embodiment of the present invention and the user is supine.
When the user lies on the mattress M, the body pressure is transmitted to the floor 3 via the mattress M. At this time, although the body pressure is absorbed by the mattress M to some extent, a load is applied to the floor 3 according to the magnitude of the body pressure. For this reason, when the user lies on his back, the leaf spring 4 located near the user's buttocks (pelvis) where a large body pressure is applied is subjected to a large load and the amount of elastic deformation increases, and the spine does not apply a great body pressure. The leaf spring 4 located in the vicinity of the (lumbar vertebra) is hardly applied with a load and the amount of elastic deformation is small. And since both the back floor part 31 and the leg floor part 33 are comprised with the rigid raw material, they do not elastically deform.
As described above, since the floor 3 can be elastically deformed according to the body pressure only at the waist floor 32, the support force can be improved by specializing in the waist of the user.

  In the conventional bed frame in which the entire floor portion is configured by a leaf spring, the entire floor portion is elastically deformed to allow the body pressure distribution of the entire body of the user, and to cope with the S-curve of the spine. Therefore, the user can obtain a feeling of support for the whole body, but cannot obtain a special feeling of support for the lower back, and cannot obtain a good sleeping comfort. In this respect, in the bed frame of the present invention, by adopting the configuration as described above, it is possible to improve the user's feeling of support for the waist and improve the sleeping comfort.
