Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a bed base, a mattress, and a nursing bed using a spiral net.
[0002]
[Prior art]
A hollowless helix, which has no cavity at the center, can resist expansion and contraction and bending, unlike a general spring coil.
Various proposals have been made for structures using a spiral wire.
For example, JP-A-8-290501 and JP-A-8-291587 disclose that a number of spiral bodies formed by spirally winding a wire having a predetermined diameter are formed such that mutual valleys and peaks are laterally associated. A spiral structure and an architectural component which are assembled and fixed in a state in which they are assembled are disclosed.
[0003]
Japanese Patent Application Laid-Open No. 9-314709 discloses that a combined member composed of a plurality of spiral bodies formed by spirally winding a wire having a predetermined diameter is restrained by a restraining member while engaging peaks and valleys. A helical structure is disclosed that allows for association by side association.
Furthermore, a wire processed into a spiral with the center of the wire approaching zero as close as possible is tightly adhered without gaps when it is laterally associated, and when assembled into a net, a tough net with a stable shape can be formed. It is disclosed in Japanese Unexamined Patent Publication No. 2001-336048.
However, Japanese Patent Application Laid-Open No. 2001-336048 discloses a close-knit spiral network as shown in FIG. 1, and a structure using this spiral network includes a combination of a plurality of curved plates and a cylinder. Only a reticulated body is disclosed, and their specific uses have not been considered.
[0004]
Also, various proposals have been made for a nursing bed. For example, Japanese Patent Application Laid-Open No. 2002-360641 discloses a case in which a cared person is lying at a position slightly shifted left or right from the center. However, there is disclosed a nursing bed capable of guiding the user from a state of lying down to a bedside, and a mattress used in the nursing bed.
However, many caregivers do not want a bed or soft mattress to wake them up, but rather want to sleep on a futon on a tatami mat. Nevertheless, those who actually need nursing care tend to rub on the floor when sleeping on the tatami mats, and those who care for them need to be as high as a normal bed from the viewpoint of workability.

BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described in detail with reference to FIGS.
FIG. 1 is a plan view illustrating a spiral net formed by spirally processing a wire used in the present invention, and FIG. 2 is a perspective view showing a three-dimensional shape thereof.
In FIG. 1, the spiral net has a structure in which a longitudinal meridian 1 and a horizontal weft 2 are knitted. In FIG. 1, the spiral directions of the spiral wires constituting the meridian 1 and the latitude line 2 are all left-handed, which is a stronger structure than in the case where the winding directions are different, and the mesh is circular. The design is excellent because it has a pattern in which squares are alternately arranged.
The material and size of the spiral wire used in the present invention are not limited, but from the viewpoint of strength, workability, and assembly workability, for example, using a wire made of mild steel excellent in workability, the wire diameter is 1 to 5 mm, It is preferable that the outer diameter of the spiral is about twice the diameter of the wire and the pitch of the spiral is 5 to 8 times the diameter of the wire.
[0010]
FIG. 3 is a diagram exemplifying a spiral net used in the present invention, and is a diagram showing a structure of the spiral net of FIG. 1 in which two meridians and two latitude lines are removed.
In this way, by thinning out the meridians 1 and the latitude lines 2 of the spiral mesh, the flexibility of the spiral mesh can be adjusted appropriately.
Since the spiral net used in the present invention is constituted by a spiral wire, even after being assembled into the spiral net, the spiral wire is advanced or retracted by rotating the spiral wire, and the net can be easily disassembled, and the wire can be partially replaced or added easily. Has features that can be.
[0011]
FIG. 4 is a diagram illustrating an embodiment of a bed base using a spiral net, and FIG. 5 is a detailed view thereof.
4 and 5, 3 indicates a spiral mesh, 4 indicates a frame material, 5 indicates a reinforcing material, 6 indicates a tatami mat, and 7 indicates a spot weld.
As shown in FIG. 4, the above-described spiral mesh 3 is fixed by spot welding 7 inside a frame member 4 made of an angle material having a size of, for example, about 30 mm × 30 mm × 3 mmt.
The flexibility of the spiral net 3 can be freely controlled by adjusting the diameter of the spiral wire, the pitch, the interval of the spiral, or the material of the spiral net 3, so that the weight and preference of the cared person can be adjusted. It is possible to provide a tailor-made bed base with appropriate flexibility.
The size of the mesh of the spiral mesh 3 used in the present invention does not matter, but it is preferable to appropriately select the size of the mesh of the spiral mesh 3 in the range of 10 mm to 60 mm in order to maintain flexibility as a bed.
[0012]
Further, the interval between the spiral wires constituting the spiral net 3 may be constant, but as shown in FIG. 4, when a person lays down, the interval between the spiral wires at a position corresponding to, for example, a waist portion is locally increased. By appropriately hardening this portion, floor rubbing can be made less likely to occur even when the cared person becomes bedridden for a long period of time.
When the spiral net 3 has high flexibility, it is preferable to provide a reinforcing material 5 of, for example, about 40 mm × 3 mmt so that the bed base does not sink excessively.
In the present invention, the mattress to be installed on the bed base is not limited. For example, by installing the tatami mats 6 indicated by dotted lines in FIGS. Beds can be provided.
[0013]
FIG. 6 is a diagram illustrating an embodiment of a mattress using a spiral net.
In FIG. 6, 3 is a spiral mesh (lower surface), 3 'is a spiral mesh (upper surface), 4 is a frame material, and 5 is a reinforcing material.
By installing the above-mentioned spiral mesh on the upper surface and the lower surface of the mattress, a mattress having appropriate flexibility can be provided.
Further, the distance between the spiral wires constituting the spiral nets 3 and 3 'is locally dense, and the positions where the local spirals are densely set are the spiral nets (3 and 3') provided on the upper and lower surfaces. According to the height of the cared person, by using a different position, for example, by using a surface where the locally dense portion matches the waist position of the cared person as the upper surface of the mattress, the body shape of the cared person We can provide a mattress that suits your needs.
As described above, by using the bed base and / or mattress using the spiral net of the present invention, it has appropriate flexibility according to the body shape and preference of the cared person, and has a simple structure and low cost. It is possible to provide a comfortable nursing bed.

【The invention's effect】
ADVANTAGE OF THE INVENTION According to this invention, a bed which has moderate flexibility for a care receiver and does not easily cause floor rubbing by using a spiral net made of a spiral wire obtained by spirally processing a wire as a spring of a bed base and / or a mattress. A base, a mattress, and a nursing bed using them can be provided, and specifically, the following industrially significant effects are obtained.
1) The care recipient is less likely to rub on the floor because of moderate flexibility and uniform deformation.
2) The structure is simpler and cheaper than a board made by combining springs.
3) It is hard to cause sagging or deformation even for long-term use.
4) Even if the care-receiver falls on the bed, the shock is absorbed, so that the safety is high and the care-receivable is hard to be deformed.
