Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention is designed to be easy to move, quick to adjust height, and gentle for people who do not climb up their feet and those who have difficulty walking to avoid the inconvenience and danger of having a step at the entrance. It concerns the installation of a solid stepped platform with a slope.

[0002]

[Prior art]

 Conventionally, in houses, the height of the steps is not constant in each place, so they are designed and manufactured individually as shown in Fig. 5.

[0003]

[Problems to be solved by the device]

 Conventionally, it had the following problems. There were no standardized products because the height of each step in the house was different. This must be solved by individually designing and manufacturing, so it is not possible to deal with it when necessary and take immediate action. The present invention has been made in view of such problems of the related art.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the inclined stepped foot with height adjustment of the present invention has an inclined flat plate on its upper part and a horizontal bottom plate on the opposite side to one side of these plates. One of the ends is connected by a hinge. The other end of each of the two flat plates is a set of hinges with free rotation, a coarse adjustment plate locked and fixed to the hinges, and a screw for adjusting the height stepwise in combination with the coarse adjustment plate. Adjustable plate, high nut that is aligned with it and can be finely adjusted in height, and a holder that supports these and a fixing piece that locks this, and can be installed immediately according to the height of the step Is.

[0005]

[Embodiment of the invention]

 An embodiment of the invention will be described with reference to the drawings. 1 to 4, the inclined plate A of the step is, for example, at least a thickness of 1.5 to 2. Plywood of about 0 cm, or reinforced plastics, aluminum plates, or steel plates that can withstand the load of the human body, etc. may be used, but in this case, it is advisable to attach measures such as slip prevention measures against walking to the upper surface. More specifically, the side surface of the step is substantially alligator and the slope of the inclined plate A can be coped with by connecting each side end of the upper inclined plate A and the lower bottom plate B with a hinge C. It has a degree of freedom. In addition, a set of supporting hinges 1 made of steel, all having load bearing strength, a coarse adjusting plate 2 and a screw adjusting plate 3, and a high nut aligned therewith, are provided at the position opposite to the one end described above. 4, a holder 5 for supporting them, a fixing piece 6 for fixing them, and a safety band 7. When the height of the step changes, that is, when the inclination of the inclined plate A changes, the hinge 1 with support freely rotates, and further, the coarse adjusting plate 2 and the screw adjusting plate 3, which are locked / fixed to the hinge 1, are supported. The high nut 4 can be positioned almost vertically with respect to the bottom plate B.

[0006] Furthermore, with respect to the height change of the inclined plate A, a set of a coarse adjustment plate 2 and a screwed adjustment plate 3 are combined to adjust the height stepwise, and if necessary, a screw is added. By finely adjusting the adjusting plate 3 and the high nut 4, the height of the inclined plate A can be matched with the height of the step.

The variable range of the height of the step can be set by selecting the number of screw holes of the rough adjusting plate 2 and the screw lengths of the screw adjusting plate 3 and the high nut 4.

If the height of the step is large, a turnbuckle can be used as an alternative to the high nut 3. If the height of the step is low, the coarse adjustment plate 2 can be removed and the adjustment plate with screw 3 and the high nut 4 can be used.

After adjusting and setting the height of the inclined plate A, the base position of the high nut 4 and the holding position of the holder 5 in the horizontal longitudinal direction are adjusted so that the fixing piece 6 securely locks.

A safety band is attached to the outer periphery of the high nut 4 so that the high nut 4 does not float up from the holder 5 and is securely locked to the bottom plate B. Rubber is attached to the back surface of the bottom plate B to prevent slippage of the entire step. Place the crocodile surface of the step on the side of the step in parallel.

[0011]

[Effect of the invention]

 Since the present invention is configured as described above, the following effects can be obtained.

With respect to the height of the step, the pair of supporting hinges facing each other according to claim 1 rotate, and the vertical position of the coarse adjusting plate connected thereto is substantially determined. Since the structure is such that the coarse adjustment plate and the screw adjustment plate are combined in stages and the high nut is turned to make a fine adjustment, it is only necessary to align the upper surface of the inclined plate with the height of the step without measuring the height. The base position of the high nut moved by the rotation of the supporting hinge can be firmly and securely locked by the holding tool and the fixing piece that support this. Moreover, it can be easily moved and installed in a place with a step.

Depending on the height of the step, when the height applicable range of the step is exceeded, the number of screw holes is set for the pair of rough adjusting plates facing each other according to claim 2, and the number of screw holes is set for the adjusting plate with screw and the high nut. It can be dealt with by preparing a new screw length and replacing it.
