Abstract

PROBLEM TO BE SOLVED: To provide an easily movable, height adjustable and strong step with a slight inclination for securing the safety of walking since a place with a level difference at the gateway of a building is an obstacle for a person who can not raise feet. SOLUTION: For an inclined plate A and a horizontal bottom plate B, both end parts on one side are connected by a set of hinges C. A set of rotary shaft fixing parts 1 and rotary shaft supporting bodies 2 and long screws 3 and high nuts 4 directly connected to them are provided on the other side end part of the inclined plate A. A set of holders 5 for holding the high nuts 4 and fixing pieces 6 for fixing them are provided on one side end part of the bottom plate B. Matched with the height of the level difference, the height of the inclined plate A is decided by using the long screws 3 and the high nuts 4. A position to perform fixation at the base part of the high nuts 4 is horizontally moved by the change of an angle α formed by the inclined plate A and the long screws 3 and the position change is fixed by the holders 5 and the fixing pieces 6. The high nuts 4 are fixed by safety bands 7 and this step is tightly adhered and installed to a level difference side face.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a person who does not
And installation of a solid platform that is easy to move, can be quickly adjusted in height, and has a gentle slope to eliminate the inconvenience and danger of steps for people with walking difficulties It is.

[0002]

2. Description of the Related Art Conventionally, houses have been designed and manufactured individually as shown in FIG. 5 because the height of steps is not constant at each place.

[0003]

Conventionally, there have been the following problems. There are no standardized products because the height of the steps varies from place to place in the house. Because of this, it had to be solved individually or by making it specially, so that it was not possible to use it when needed and take immediate action. The present invention has been made in view of such conventional problems.

[0004]

In order to achieve the above-mentioned object, a height-adjustable inclined platform according to the present invention has an inclined flat plate at an upper portion and a horizontal bottom plate at a lower portion opposite to the inclined flat plate. And
These one-side ends are connected to each other with hinges, thereby forming a substantially crocodile mouth shape. In addition, the other one end of the two flat plates is a support having a set of rotating shafts that can freely rotate with respect to the height change of the inclined plate and a long screw that can be adjusted in height and joined thereto, And a height nut, a holder for supporting the nut and a fixing piece for fixing a position generated by the height change, and the height position can be set steplessly in accordance with the height of the step.

[0005]

[Function] The inclined step with height adjustment adjusts the height to the height of the step side by rotating a pair of high nuts of the step, and the height is changed by changing the length of the long screw and the high nut. The movement of the base position of the nut is received by the support, and the position is fixed by the lower fixing piece.

[0006] By attaching a safety band to the outer periphery of the high nut, it is possible to prevent the holder from being lifted up and removed from the holder in case of emergency. The crocodile mouth surface of the step is closely attached to and parallel to the step side surface. The rubber adhered to the back surface of the bottom plate prevents the entire platform from slipping.

[0007]

Embodiments of the present invention will be described with reference to the drawings. In FIG. 1 to FIG. 4, as the inclined plate A of the step, for example, a plywood having a thickness of at least about 1.5 to 2.0 cm, or a vinyl chloride resin or an aluminum plate having strength enough to withstand a load such as a human body may be used. In this case, it is advisable to attach a slip prevention measure against walking, a sheet or the like to the upper surface. More specifically, the side surface shape of the step is substantially crocodile mouth shape, and the slope of the inclined plate A can be handled by connecting each 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, at a position opposite to the one end, a set of a rotating shaft fixing portion 1 and a rotating shaft support 2 which are all made of steel having a load bearing strength, and a long screw 3 and a high nut 4 to be joined thereto. Further, it comprises a holder 5 for supporting them, a fixing piece 6 for fixing the same, and a safety band 7. When the height of the step, that is, the gradient of the inclined plate A changes, the rotating shaft fixing portion 1 and the rotating shaft support 2 connected to the rotating shaft fixing portion 1 can freely rotate. The long screw 3 joined to the support 2 is a bottom plate B
The vertical position can be taken with respect to.

Further, in response to a change in the height of the inclined plate A, the height of the inclined plate A is adjusted by turning a set of high nuts 4 and adjusting the length of the long screw 3 in the longitudinal direction. It can be matched steplessly.

In general, the variable range of the height of the step can be set by selecting the lengths of the long screw and the high nut. However, it is necessary to reduce the overlap portion by about 1.5 cm from both lengths.

When the height of the inclined plate A is set by turning the long screws / high nuts 3 and 4, the angle α formed between the inclined plate A and the long screw 3 changes. In order to set the long screw 3 and the high nut 4 to be always perpendicular to the bottom plate B, the base position of the high nut 4 and the longitudinal position of the holder 5 are adjusted and the fixing piece 6 is securely used. Lock.

A safety band is attached to the outer periphery of the high nut 4 and securely locked to the bottom plate B so that the high nut 4 is lifted from the holder 5 and does not come off. Rubber is attached to the back surface of the bottom plate B in order to prevent slippage of the entire platform.

[0012] The crocodile mouth surface of the step is closely attached in parallel to the step side surface and installed.

[0013]

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

With respect to the height of the step, the slope of the inclined plate is uniquely determined by the pair of the hinges, the rotating shaft fixing portion and the supporting member, which are opposed to each other, in conjunction with this displacement. As a result, the appropriate length can be set steplessly with the long screw and the high nut, and the holder and the fixing piece can be set firmly and securely. Further, it can be easily moved and installed in a place having a step.

A second aspect of the present invention comprises a pair of opposed rotating shaft fixing portions having rotating shafts that can be freely angled and a rotating shaft support. The load applied to the inclined plate acts evenly on one side of the two pairs of long screws and high nuts evenly, and it can rotate freely so that it is always perpendicular to the bottom plate. It is only necessary to adjust the upper surface of the inclined plate to the height of the step without measuring the gradient, that is, the height.

By turning a pair of long screws and a high nut opposed to each other and setting the height of the inclined plate in a stepless manner, the base position of the high nut moves. The position corresponding to this movement and moved in the longitudinal direction of the holder is locked by a fixing piece. Since these have a withstand load, they can be reliably locked without causing any loosening in the long term.
