Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a floor plate device constituting a floor plate undulating bed.

(Prior art and its problems) For example, if a person uses a general household wooden bed with a fixed floorboard and desires a back-lifting function,
Conventionally, there is no way to easily modify the floorboards, so a new bed with a back-raising function has to be purchased, which increases costs and makes the existing bed useless and requires disposal. In addition, the floor width of the bed itself with a back-raising function varies by, for example, 20 to 30 mm depending on the type, so it is necessary to individually design and manufacture a back-raising floor plate that is suitable for each type. The problem is that it is difficult to reduce costs.

The present invention aims to solve the above-mentioned conventional problems.

(Means for solving the problems) The configuration of the present invention is shown in FIGS. 1 to 4 corresponding to embodiments.
To explain based on the drawings, the present invention has an undulating floor plate 1
In the support frame 2 which rotatably supports the bed 3
A fitting cylinder 6 that telescopically fits and supports the support rod 5 of the mounting member 4 is provided on both sides corresponding to the longitudinal direction of the mounting member 4. A fixing member 7 is provided, and the mounting member 4 is attached to a mounting protrusion 9 formed in the inner longitudinal direction of the longitudinal frame member 8 of the bed 3.

Here, the mounting member 4 is attached to the bed 3 as described above.
If the configuration is such that it is attached to the mounting ridge 9 formed in the inner longitudinal direction of the longitudinal frame member 8, it is constructed as a hook-shaped plate that is hooked to the upper surface of the mounting ridge 9 as shown in FIG. Other configurations can be made as appropriate as shown in the embodiments described later.

(Function) In the above configuration, when constructing a bed with a floor plate that can be raised and lowered, the distance between the mounting members 4 on both sides is first adjusted in accordance with the distance between the longitudinal frame members 8 on both sides. Adjustment of the interval is carried out by extending and contracting the support rod 5 relative to the fitting cylinder 6 and fixing it at a predetermined extension and contraction position with a fixing member 7 such as a tightening screw. After adjusting the distance between the mounting members 4 on both sides in this way, the mounting members 4 are attached to the mounting ridges 9 formed on the inside longitudinal direction of the longitudinal frame member 8 as shown in FIGS. 1b and 1c. As a result, the support frame 2 is fixed to the longitudinal frame member 8, and the undulating floor plate 1 can be rotatably supported at a predetermined position on the bed 3. By attaching an appropriate lifting mechanism member such as a screw shaft type floor plate lifting mechanism or a gas spring type floor plate lifting mechanism to an appropriate position on the bed 3, a bed with a raised/lower floor plate can be constructed. The elevating mechanism member can be attached more easily than the case where the undulating floor plate 1 itself is rotatably fixed, and therefore, the attachment method can be selected as appropriate. Next, the fourth
As shown in the figure, if a person using a general household wooden bed 3 with a fixed floor plate A desires a back-raising function, first install a floor plate that corresponds to the position where the undulating floor plate 1 should be installed. Remove part A. In a typical household wooden bed 3, the floor plate A is supported by a mounting protrusion 9 formed on the inside longitudinal direction of the longitudinal frame member 8, so after removing the floor plate A part, the same procedure as described above is carried out. The support frame 2 can be attached to the longitudinal frame member 8, and after the undulating floor plate 1 is rotatably supported at a predetermined position on the bed 3, the appropriate elevating mechanism member is attached to the appropriate position on the bed 3 in the same manner as described above. By attaching it, it can be converted into a bed with a floor plate that can raise the back.

In the above description and illustrated examples, the undulating floorboard 1 is only the back floorboard, but it goes without saying that the lumbar floorboard and the foot floorboard can also be configured to undulate together with the back floorboard.

(Embodiment) Fig. 2 shows another embodiment of the mounting member 4, in which the hook-shaped piece 10 is movable in the vertical direction with respect to the main body 11 of the mounting member 4 and can be fixed thereto. With this configuration, the supporting height of the undulating floor plate 1 with respect to the longitudinal frame member 8 can be adjusted, and a plurality of guide grooves 12 are provided to allow the hook-shaped piece 10 to move freely in the vertical direction. By making the attachment position of the hook-shaped piece 10 variable, no problem will occur even if a projection or the like is partially formed on the upper surface of the attachment protrusion 9. Next, FIG. 3 shows still another embodiment, which has a structure in which, together with a hook part 13 for attaching to the upper surface of the mounting protrusion 9, a screw is attached to the inside of the longitudinal frame member 8 on the upper and lower sides. 14, and this configuration can cope with the lack of strength of the mounting protrusion 9.

Next, the elevating mechanism for the undulating floor board 1 shown in FIG. The operating arm 17 that rotates the arm 15 is driven by a gas spring or a screw shaft type telescoping rod (not shown), but the elevating mechanism may have any suitable configuration.

(Effects of the invention) As described above, the present invention provides a mounting member on the support frame that rotatably supports the undulating floor plate, and attaches this to the mounting ridge formed on the inside longitudinal direction of the longitudinal frame member of the bed. This is the undulating floor plate part of the undulating floor board bed, so if a person who uses a general household wooden bed with a fixed floor board desires the undulating function of the floor board, such as raising the back. , it is possible to easily remodel the existing bed without disposing of it, and a bed with a floor plate undulating function can be obtained at a low cost.
At this time, since the mounting width of the mounting member is variable, there is an advantage that the bed that can be modified can be modified regardless of the type or manufacturer as long as it has the mounting ridges described above. In this way, the present invention not only allows existing beds to be modified into a bed with an undulating floor plate, but also can be used as a component of a regular bed with a undulating floor plate. This has the effect of reducing costs by standardizing parts.
