<About the structural problems of the conventional lift device that combines stairs>

Stairs are structures installed to move between two spaces with a difference in height, and are used for a wide variety of purposes, such as the entrance of a building, movement between floors inside a building, as well as means of transportation such as trains and buses. .

These stairs are mainly used by the general public. Since wheelchairs and strollers used by the elderly and patients with reduced mobility cannot be used, it is legally compulsory to install a ramp for movement around the stairs for the movement of wheelchairs or strollers. There, the ramp is installed so that the length of the ramp is 12m or more when the step difference between the two floor surfaces is 1m.

However, since the installed ramp must have a horizontal section and an intersection section for entry and exit, respectively, at both ends in the longitudinal direction, the total length of the ramp is constructed at 15 m, which causes an increase in construction cost and low space utilization. .

In addition, in the case of the ramp, construction is possible if space for installing the ramp can be secured around the stairs, but when structures with different heights are installed on the same floor indoors, such as auditoriums, gymnasiums, concert halls, etc., the surrounding space is very It is impossible to install due to narrowness, or commercial facilities and religious facilities are often reluctant to install due to the problem of narrow space as well as fear of damaging aesthetics.

Patent documents described in the prior art disclose a plurality of drive units installed vertically at the corners of the upper and lower platform so that the length is each stretched by an external power source to raise/lower a wheelchair or a stroller boarded by an elderly person or a disabled person. And, among the plurality of driving parts, a plurality of guide parts connected to and installed with each driving part installed on the upper platform side to support the safe and smooth ascending / descending of the driving part, and a number of guide parts that can be used by ordinary people A variable elevation unit whose upper surface is changed from a staircase shape to a flat platform shape by the drive of the drive unit, which rises/falls when a boarding body rides on the top, safely moves the boarding body, and then returns to its original state in the form of a staircase, and switches the drive unit It comprises a control unit that is driven by manipulation so that the variable lift can be converted from a stair to a platform.

The prior art made as described above can be used by pedestrians who can walk by configuring the form of stairs at normal times, and in order to move a wheelchair or stroller, it is converted into a flat platform form, and after placing the wheelchair or stroller on the platform, the platform is raised or Move a wheelchair or stroller by lowering it.

In this prior art, the height of the stairs is adjusted by operating a plurality of drive units to configure the shape of the stairs or convert them into a platform. As the side frame rotates, the side frame is rotatably supported in the process of adjusting the height of the footrest, and in a state where the side frame is fixed, it is necessary to maintain horizontality in order to serve as the floor of the stairs or lift.

As described above, the conventional scaffolding has to be rotatably supported on the side frame, so it is combined with the side frame through a single axis of rotation, and solves the difficulty of maintaining the horizontality that occurs at this time and improves the stability of moving pedestrians, wheelchairs and strollers. A support for preventing a side fall is provided to provide a horizontal level of the footrest.

However, the conventional scaffold has a problem in that it is difficult to maintain the horizontality of each scaffold because the coupling part with the side frame is coupled only through one axis of rotation. There was a problem inevitably forming a gap between them.

Here, among the configurations of the variable elevation unit 300, the characteristic configuration of the present invention will be described in detail below. A pedestrian or a vehicle moves while being converted into a staircase or a lift, and the stair plate 340 and the side frame 350 constituting the variable elevation part 300 and the rotating means 600 disposed at their coupling part Through this, it is possible to maintain the horizontality of the stair board 340.

That is, the upper surface of the stair board 340 is made of a flat surface so that a pedestrian or a vehicle moves. Since it is a dog part, there is a problem in that the level of the step board 340 is not maintained and displaced in the process of moving by stepping on or pressing the step board 340.

Of course, the angular displacement of the stair plate 340 is prevented through the support 330 to which the stair plate 340 is coupled and the handrail 320 to which the support 330 is coupled, but the pressure transmitted to the stair plate There is a problem in that it is concentrated on the joint with the support or the joint between the support and the handrail, thereby damaging the corresponding portion.

Therefore, in the present invention, by disposing the rotating means 600 at the joint between the stair board 340 and the side frame 350, angular displacement of the stair board is prevented and horizontal stability is provided.

The rotating means 600 couples the side frame 350 and the stair board 340, and allows the side frame 350 to be rotatably disposed in a state of being coupled to the stair board 340.

The rotation means 600 for this purpose is formed with support shafts 610 provided at both ends of the step plate 340 and coupling holes disposed on the handrail 320 and coupled to the support shafts 610, A rotation body 620 having one side opened, and a plurality of rotation clamps 630 rotatably disposed on the rotation body 620 and supporting the rotation body 620 while touching or spaced apart from the inner surface 621 of the rotation body. ), and is coupled to one side of the opening of the rotation body 620 and is installed to surround the outer circumference of the support shaft 610, and rotates in conjunction with the rotation of the rotation body 620 while rotating the rotation clamp 630. It includes a cover 640 that presses against the inner wall of the body to make it adhere or to be spaced apart from the inner wall.

The support shaft 610 is formed in the form of a circular rod extending outward from both ends of the step board 340 in the longitudinal direction, respectively, and is drawn into the handrail 320 .

The rotating body 620 is disposed on the side frame 350 and has a coupling hole to which the support shaft 610 is coupled. At this time, the rotating body 620 is formed integrally with the side frame 350 or formed separately, It is integrally fixed to the side frame 350 through a coupling method such as welding.

Since the shape of the rotating body 620 is a part exposed to the outside, it can be made in various shapes in consideration of design factors and safety, but the inner surface is configured to form a circular shape, which will be described later. ) It is to provide a moving path and at the same time provide an area where the rotary clamp 630 adheres.

The rotating clamp 630 is rotatably disposed inside the rotating body 620 and is disposed so as to be rollable in contact with the outer circumferential surface of a cover 640 to be described later, and is in contact with the outer circumferential surface of the cover 640. A plurality of rollable casters 631 are provided, and resistance pads 632 that come into contact with the inner circumferential surface of the rotating body 620 to form frictional resistance are provided in a direction opposite to the disposition of the casters 631 .

Here, the resistance pad 632 is made of a soft material having its own elastic restoring force, and when it comes into contact with the inner circumferential surface of the rotating body 620, resistance is formed at the contact portion to prevent angular displacement of the footrest.

The cover 640 is coupled to the open surface of the rotating body 620 to close the inside of the rotating body 620 and is installed to cover the outer surface of the support shaft 610 coupled to the rotating body 620. do.

In addition, a plurality of protruding pressurizing parts 641 are provided on the outer circumferential surface of the cover 640 at intervals from each other so that the rotating clamp 630 comes into contact with or is spaced apart from the inner circumferential surface of the rotating body 620 while riding or unriding. do.

The cover 640 covers the outer circumferential surface of the support shaft 610 and rotates simultaneously when the rotation body 620 interlocks with the side frame 350 in a coupled state, and at this time, the protruding pressing unit 641 moves. While the rotating clamp 630 rises or falls along the protruding pressing part 641, it comes into contact with the inner surface of the rotating body 620 to generate frictional resistance to fix the position of the footrest or, conversely, from the inner surface of the rotating body 620. It is spaced apart so that the side frame 350 can rotate.

This rotating means 600 is to prevent the angular displacement of the stair plate 340, that is, the footrest that the wheels of a pedestrian, wheelchair or stroller come into contact with is a support shaft 610 provided at both ends in the longitudinal direction as described above. It is combined with the side frame 350 only, because the side frame 350 converts the footrest into a staircase or lift while rotating.

Therefore, there is a problem in that it is difficult to maintain the level of the scaffold only with a pair of supports 330 provided at both ends in the longitudinal direction of the scaffold, and as a result, the width of the scaffold cannot be increased, as well as the Since angular displacement occurs frequently, there is a problem in that movement safety of pedestrians and wheelchairs is low.

Of course, it is possible to partially guarantee the horizontal stability of the scaffold through a pair of supports 330 vertically disposed on the upper surface of the scaffold and the handrail 320 to which the support frame is connected, but the load pressure is excessively transmitted or momentarily When the force is concentrated, the pressure is concentrated on the connection part between the support frame and the handrail and the corresponding part is damaged. An accident such as a pedestrian's foot or a wheel of a wheelchair or stroller getting caught in the gap may occur.

Therefore, it is necessary to prevent the angle of the scaffold from being displaced regardless of whether the stairs or the lift are used in any form.

In the present invention, for this purpose, the rotating body 620 is placed on the side frame 350, a plurality of rotating clamps 630 are placed inside the rotating body 620, and then the rotating clamp 630 is attached to the support shaft 610. ) is rotated between the inner circumferential surface of the cover 640 and the rotating body 620, and the resistance pad 632 provided in the rotating clamp 630 is in close contact with the inner circumferential surface of the rotating body 620 to rotate through frictional resistance generated. By preventing the body 620 from rotating, angular displacement of the step board 340 is prevented.

Through this, it is possible to use a stable scaffolding, as well as to prevent the risk of accidents, and since the cover 640 is detachably coupled to the rotating body 620, maintenance and repair of the rotating clamp, etc. It is easy and it is possible to repair and replace only the scaffolding or components that have a problem, so the economical effect of reducing the time and cost required for maintenance can also be expected.
