Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a pine tress, and particularly to the structure of a bending portion in a bendable pine tress.

[Conventional technology]

Generally, as shown in FIG.
It is well known that there are bendable types. By adjusting the inclination angle of the mattress 3 using an adjustment mechanism (not shown), the patient's upper body or legs can be raised up.

As shown in FIG.
5 and a plurality of hourglass-shaped spring members 6, 6 located inside the frame lines 4, 5, and each spring member 6, 7 is connected to each other by a connecting line. The bent portions 7, 7 of the upper and lower frame lines 4, 5 are formed by dividing the frame lines 4, 5 as shown in FIG. 5, and connecting the divided portions with substantially U-shaped hook portions 7A, 7B. There is something configured.

Furthermore, as shown in FIG. 6, there is a structure in which divided parts are connected to each other by springs 8, 8.

[Problem that the invention seeks to solve]

However, according to the structure of the bending part shown in FIG. 5, when the bending part 7 is bent, the hook part 7A,
7B was caught, and the bending portion 7 could not be smoothly bent, resulting in deformation in other parts. Furthermore, according to the structure of the bent portion shown in FIG. 6, since the frame lines 4 and 5 are separated, the shape-retaining force of the frame lines 4 and 5 around the edges of the pinerest is weakened, especially in the vicinity of the bent portion. The shape-retaining ability of the pine tree is weakened, and when your body is around the edge, you not only sink a lot and feel uncomfortable, but also have the disadvantage that there is a risk of falling off the pine tress.

[Means for solving the problem] The present invention connects spring members to form a planar body, and the outer periphery of this planar body is surrounded by a frame member having approximately the same height as the planar body and a constant width. At the same time, the bent portions of the frame material are separated, and the separated portions are connected with a soft cushion body to make it bendable, and the holding force of the bent portion is increased. This is to prevent a decrease in

[Effect]

Since the soft cushion body is interposed at the bent portion of the frame material, the frame material can be bent freely at this portion.

〔Example〕

FIGS. 1 and 2 are an exploded perspective view and a sectional view showing an embodiment of the pine tress according to the present invention, and in the same figure, 20 is a rectangular frame member, which is
For example, it is made of natural or synthetic fibers or a mixture thereof, has a rod shape, and has a certain height. In this case, the frame material 20 is divided at the bent portion, and the divided portions are connected to the cushion bodies 21 and 21.
They can be bent freely by connecting them to each other through the . The cushion body 21 may be adhered to the divided portion of the frame member 20 using an adhesive. A plurality of spring members 22, 22 are connected to the inside of the frame material 20 by connecting lines 2.
3 and 23 are connected to each other to form a planar body, and upper and lower surface materials 24 and 25 are attached above and below the frame material 20. Surface material 2
4 and 25 are made of, for example, natural or synthetic fibers, a mixture thereof, a soft synthetic resin foam, or the like. The entire member is housed in a bag-shaped decorative member to complete the pine tress.

According to the above configuration, as shown in FIG. 2, the mattress can be easily bent up and down at the bending portions 7, 7 in which the cushion bodies 21, 21 are interposed.

According to such a configuration, the bending part can be smoothly bent without causing any catch as in the conventional case, and the outer periphery of the planar body formed by connecting the spring members 22 can be connected to the frame material. 20, this frame material 20 improves the shape retention around the edge of the pine tress, and even if your body comes around the edge, there is less sinking, so you won't feel uncomfortable, and you won't feel like falling off the pine tress. It can also prevent situations. Furthermore, the conventional frame lines 4 and 5 made of elastic wire can be omitted, simplifying the structure and reducing costs.

Claims (1)

[Scope of utility model registration request] The spring members are connected to form a planar body, the outer periphery of this planar body is surrounded by a frame material having a constant width and approximately the same height as the planar body, and surface materials are placed on the top and bottom surfaces of this frame material. A pinerest characterized in that the bending portion of the frame material is divided and the divided portions are connected by a soft cushion body so as to be freely bendable.
