Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to legs for supporting the head and foot sides of a floorboard support frame to form a bed, and in particular, the support height of the floorboard support frame. It concerns adjustable legs.

(Prior art and its problems) Attach and support the head and foot sides of the floorboard support frame,
An example of a conventional leg body that allows adjustment of the support height of the floor plate support frame is shown in FIGS. 4a and 4b, for example. This leg body a is provided with vertically long mounting plates c on the left and right pillars b by welding or the like, and a plurality of engagement protrusions d protruding in the length direction of the mounting plates c. , hook-shaped engagement pieces f protruding from the head and foot sides of the floorboard support frame e are engaged with this protrusion d to support the floorboard support frame e as shown in item 4b. .

However, in such a conventional configuration, the protrusion d of the part that does not engage the engagement piece f and the mounting plate c
Since it is exposed, it is dangerous and does not look good.

The present invention aims to solve these conventional problems.

(Means for solving the problems) The configuration of the present invention is shown in FIGS. 1 to 3 corresponding to embodiments.
To explain based on the drawings, the present invention comprises a fitting cylinder part 3 on the mounting member 2 of the floor plate support frame 1, and the fitting cylinder part 3 can be moved up and down to the left and right pillars 5 of the leg body 4. In addition to freely fitting together, the inner wall 6 of the fitting cylinder portion 3 is formed into an inclined surface extending from a large diameter portion at the bottom to a small diameter portion at the top,
Further, a vertically divided cylindrical member 8 of the virtual cylindrical body 7 that fits into the pillar 5 is provided, and the outer wall 9 is formed into an inclined surface that fits into the sloping surface, and the cylindrical body structure A protrusion 11 is provided on the inner wall 10 of the member 8, and a plurality of engaging portions 12 for engaging the protrusion 11 are provided in the height direction of the pillar 5.

(Function) In the above configuration, first, the protrusion 11 of the cylindrical body component 8 is engaged with the engaging part 12 of a certain height of the pillar 5, and the cylindrical body component 8 is attached to the leg. It is attached to the outside of the pillar 5, and in this state, the attachment member 2 is lowered, and the fitting tube portion 3 is attached to the tube-shaped body component member 8 from above.
When fitted to the outside, the inner wall 6 of the fitting cylinder portion 3 and the outer wall 9 of the cylindrical body constituent member 8 fit together. However,
The inner wall 6 has an inclined surface extending from a large diameter section at the bottom to a small diameter section at the top, and the outer wall 9 has an inclined surface that engages with the inclined surface, that is, from a small diameter section at the top to a large diameter section at the bottom. Since it is configured as an inclined surface, the more the fitting cylinder part 3 tries to descend, the more the cylinder-shaped body constituent member 8 is pressed inward, and the inner wall 10 comes into pressure contact with the pillar 5. The engagement between the protrusion 11 and the engagement portion 12 is as follows:
Becomes more solid. In this way, the mounting member 2 is fixed at a predetermined height of the pedestal 5, and the attached floor plate support frame 1 can be supported by the mounting member 2.

Since the inner wall 6 of the fitting cylindrical portion 3 and the outer wall 9 of the cylindrical body constituent member 8 are the above-described inclined surfaces, the fitting cylindrical portion 3 and the mounting member 2 can be raised. Therefore, by raising the mounting member 2,
Release the constraint on the cylindrical body component 8, then engage the protrusion 11 with the engaging portion 12 at a desired height, lower the mounting member 2 again, and insert the fitting cylindrical portion 3 into the cylindrical shape from above. By fitting to the outside of the body component 8, the attachment member 2 can be fixed in the same manner as described above. In this way, the mounting member 2 can be fixed at a desired position of a plurality of engaging portions 12 provided in the height direction of the pillar 5.

(Example) Next, the illustrated example will be described. First, the mounting member 2 has a pair of mounting plate parts 13 on one side of the fitting cylinder part 3.
are arranged in parallel at appropriate intervals, and a pair of upper and lower engaging portions 14 are provided between the pair of mounting plate portions 13, and the pair of upper and lower engaging portions 14 are provided on the head side and foot side of the floor plate support frame 1. A mounting plate 15 that can be freely inserted between the mounting plate parts 13 is provided with a hook-shaped engagement piece part 16 that engages with the pair of engagement parts 14. In this configuration, since the mounting plate 13 is hidden between the pair of mounting plate parts 13, it can be firmly engaged and has a good appearance, and can also be configured as a corner bumper as a bed. Next, the cylindrical body component 8 has a shape in which the virtual cylindrical body 7 is vertically divided into two parts. And 2
The divided cylindrical body constituent members 8 are configured to have appropriate intervals when mounted on the pillar 5. Furthermore, the engaging portion 12 is constituted by a hole in the case of FIG. 2, and is constituted by a recessed portion in the case of FIG.

(Effects of the invention) The invention is as described above, and as a structure for freely adjusting the support height of the floor plate support frame, the pillar is engaged with a protrusion provided on the inner wall of the cylindrical body component. Multiple holes or recesses for engagement are provided in the height direction of the pillar, so the mounting plate and protrusions are not exposed as in the conventional case, resulting in excellent safety and aesthetics. This has the effect that the floor plate support frame can be firmly supported as well as being superior in terms of performance.
