Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a bed device with an improved floor plate.

(Prior Art) Generally, a bed device is composed of a bed main body, a frame installed between side members of the bed main body, and a floor plate attached to the frame.

Incidentally, in some bed apparatuses for use in hospitals, the frame is formed of a metal pipe, and a wire net is stretched over the frame as a floor plate.

(Problems to be solved by the invention) However, with such a conventionally structured bed device, the metal frame is exposed to the outside, so it looks extremely unsightly, especially when the floorboards are raised. In stand-up type bed devices that allow for easy access, the frame often stands out when the floorboards are raised. Moreover, when a load is applied to the wire net stretched over the frame, the wires collide with each other and generate noise, which sometimes disturbs a good night's sleep.

This idea was made based on the above circumstances, and its purpose was to make it possible to cover the frame with a floorboard, and to prevent the floorboard from generating noise when sleeping. The object of the present invention is to provide a bed device that eliminates the problem.

(Means and operations for solving the problems) In order to solve the above problems, this invention includes a bed body, a frame formed of a rod-shaped member provided on the bed body, and a frame formed from a rod-shaped member. It is equipped with a flat plate part that is attached and covers the upper surface side of the frame, and a synthetic resin floor plate that is integrally molded with a decorative piece that covers the peripheral part. The decorative piece improves the appearance, and the floorboard is made of synthetic resin to prevent noise during use.

(Embodiment) An embodiment of this invention will be described below with reference to FIGS. 1 to 4. FIG. 4 shows a get-up type bed device, which includes a bed body 1. As shown in FIG. This bed main body 1 is formed by a pair of side members 2 (only one of which is shown) which are spaced apart and opposed to each other in parallel, and a headboard 3 is connected to one longitudinal end thereof, and a footboard 4 is connected to the other end thereof. A receiving member 5 is provided on the inner surface of each of the side members 2 over almost the entire length in the longitudinal direction, and a frame 6 is installed on these receiving members 5 with both ends in the width direction engaged with each other.

The frame 6 is composed of a fixed frame 7 fixed to the receiving member 5 and located on the footboard 4 side, and a movable frame 8 rotatably connected to the fixed frame 7 and located on the headboard 3 side. Each frame 7, 8 is formed by connecting a pair of vertical rods 9 spaced apart in parallel along the longitudinal direction of the bed main body 1 with a plurality of horizontal rods 11. Further, a floor plate 12 is attached and fixed to the fixed frame 7 and the movable frame 8, respectively. Each floorboard 12 is made of flexible synthetic resin such as polyethylene or nylon. In other words, the floorboard 12 is
a flat plate part 13 to be joined to the upper surface of the flat plate part 13;
Decorative pieces 14 are vertically attached to the lower surface of the flat plate part 13 over the entire circumference of the flat plate part 13, and vertical rods 9 of the frames 7 and 8 are inserted into the lower surface of the flat plate part 13 in the longitudinal direction of the flat plate part 13. A pair of tongue pieces 15 protruding along the flat plate portion 13 and a plurality of reinforcing ribs 16 protruding in a lattice shape from the lower surface of the flat plate portion 13 are integrally molded. The flat plate part 13 has many ventilation holes 1.
3a is bored. The vertical rods 9 of the frames 7 and 8 inserted between the pair of tongues 15 of the floorboard 12 are attached and fixed to the tongues 15 by screws 17. Note that the floor plate 12 provided on the fixed frame 7 is divided into a plurality of parts (in this embodiment, three parts) to facilitate molding.

An arm 18 is attached to the horizontal rod 11 of the movable frame 8.
One end is fixed. One end of a drive rod 19 is pivotally connected to the other end of the arm 18. A nut body 21 is provided at the other end of the drive rod 19, and one threaded end of a screw shaft 22 is screwed into the nut body 21. The other end of the screw shaft 22 is rotatably supported by a spherical bearing 23 provided on the footboard 4, and can be rotated by a handle 24. Therefore, if the screw shaft 22 is rotated by the handle 24 and the drive rod 19 is slid, the arm 18 is rotated and the movable frame 8 is rotated.
It is designed to be able to rise and fall.

Although not shown in the drawings, a pine mattress is placed on the floorboards 12 of the fixed frame 7 and movable frame 8.

According to the bed device having such a structure, since the decorative piece 14 is provided on the peripheral edge of the floor plate 12 attached to each frame 7, 8, the frames 7, 8 are covered and hidden by the decorative piece 14. Therefore, the vertical rods 9 and horizontal rods 11 forming the frames 7 and 8
It is difficult to see from the outside, so it looks good on the outside. In particular, the vertical rods 9 of each frame 7, 8 are not only hidden by the decorative pieces 14, but also hidden by a pair of tongue pieces 1.
5, so the appearance can be further improved.

In addition, since the floorboard 12 is integrally molded from synthetic resin, it does not generate noise such as squeaks when it is elastically deformed by a user's load. Furthermore, a large number of ventilation holes 13a are bored in the flat plate portion 13 of the floorboard 12. Therefore, even if the pine tress is contaminated with moisture such as the user's sweat, the moisture can escape through the ventilation hole 13a, making it difficult for moisture to get trapped between the floorboard 12 and the pine tress, and causing the moisture to leak to the bottom surface of the pine tress. Can prevent mold from forming.

In addition, when the floor plate 12 is made of synthetic resin, it is not only lighter and easier to color, but also mass-produced, and furthermore, the lighter weight makes it possible to improve the operability of the movable frame 8.

Note that this invention is not limited to the above-mentioned example,
For example, as shown in FIG. 5, one tongue piece 15 is erected inside the decorative piece 14 at a predetermined distance from the decorative piece 14, and the vertical rods 9 of each frame 7, 8 are inserted between them. It may be installed and fixed with. Further, the bed device is not limited to one in which the floor plate can be raised and lowered, but may also be one in which the floor plate is fixed to the bed body.

(Effects of the invention) As described above, this invention provides a flat part that covers the periphery of the frame and a decorative piece that covers the periphery of the synthetic resin floorboard that is attached to the frame installed on the bed body. and are molded into one piece. Therefore, the frame can be prevented from being exposed by the flat part and the decorative piece.
You can measure the improvement in appearance. Furthermore, since the floorboards are made of synthetic resin, noise such as squeaks will not be generated during use.
