Description

{Smart stairs with a varying slope}

The present invention relates to a staircase, and more particularly, to a smart staircase which can be used as a stairway in normal times and can be converted into a slope so that the tread of the staircase can be rotated as needed to convert the stairway into a slope way.

Generally, elevators, escalators or stairs are used to climb or descend a multi-story building, subway station or underpass. In particular, a lift is provided for a disabled person who is uncomfortable with his or her legs and can lift and lower a wheelchair on one side of a stairway. In addition, elevators have a high installation cost, malfunctions and maintenance difficulties, and it is not easy for a person with a disability to operate alone without the help of another person.

In addition, since the lift is installed only on relatively long steps and is not installed on the short stairs, it is inconvenient for a person with a wheelchair to be assisted by another person.

As a conventional technique for improving this, Korean Patent Publication No. 2011-0015281 has been described. As shown in FIG. 1, the technique includes a tread 100 having a flat surface 10 and a vertical surface 11, a hinge 12 interconnecting the plurality of treads 100, An upright member 14 coupled to the sliding plate 13 and guiding the horizontal movement of the sliding plate 13, an upright member 14 connected to the upright member 14 to horizontally move the upright member 14, And installed drive means (15). Here, the driving means 15 includes a conveying member 16 coupled with the upright member 14, a lead screw 17 on which the conveying member 16 is mounted, and a motor 18 for rotating the lead screw 17 Respectively.

Therefore, when the lead screw 17 is rotated by the motor 18, the conveying member 16 horizontally moves. When the upright member and the sliding plate 13 move horizontally together with the conveying member 16, the tread 100 The flat surface 10 and the vertical surface 11 are formed to be inclined.

However, in the structure in which the flat surface 10 and the vertical surface 11 are bent in a stepped shape or an expanded slope shape, a large downward force such as jumping in a stepped shape or a slanted shape or carrying a heavy load, There is a problem in that it is costly to repair or maintain it, and that there are too many components, which is complicated to install and there is also a lot of installation cost.

<Configuration>

FIG. 2 is a perspective view schematically showing a smart staircase capable of switching to a slope according to a preferred embodiment of the present invention, FIG. 3 is a perspective view of the smart staircase of FIG. FIGS. 5A to 5C are side views illustrating the type of the tread shown in FIG. 2. FIG. 5A is a perspective view of the smart step shown in FIG.

2 to 4, the smart staircase according to the present invention includes a tread 100, a supporting member 110, an angle adjusting member 120, an angle changing device, a lid 130, and the like, .

First, the tread 100 has a width and a width such that the user can lift the tread 100, and a shaft 101 is formed at both ends in the longitudinal direction so as to be rotatable with the supporting member 110 so as to be rotatable. The shaft 101 is formed at a substantially intermediate position in the width direction so that both sides of the tread 100 with respect to the width direction when the tread 100 rotates rotate in mutually opposite directions. Therefore, both ends in the longitudinal direction of the tread 100 are firmly fastened to the supporting member 110, and by shortening the rotational distance of both ends in the width direction, a large downward force imposed on the tread can be firmly supported. Of course, the shaft 101 may be formed on one side in the width direction. The shaft 101 to which the angle regulating member 120 is mounted in the shaft 101 has a length enough to be attached to the angle regulating member 120 through the support member 110. [

5A to 5C, engaging protrusions 102 are formed on both sides of the tread 100 in the width direction. When the treads 100 are inclined, the engaging jaws 102 form the same upper surface when the engaging jaws 102 are matched with each other. When the treads 100 are inclined, the engaging jaws 102 are aligned with the engaging jaws 102 of the adjacent tread 100 to form the same upper surface to prevent excessive axial rotation of the tread 100 .

5A, the uppermost tread plate 100 is formed with a locking protrusion 102 on its side which rotates downward when it is rotated, so that the locking protrusion 102 of the uppermost treading plate 100 is engaged with the locking protrusion 102 of the tread plate 100 adjacent to the lower side It is for this reason. 5B, the lowest tread plate 100 is formed with a latching protrusion 102 on its side that rotates upward when rotated, and it is formed so as to extend over the latching jaw 102 of the tread plate 100 adjacent to the upper side, It is for this reason. As shown in FIG. 5C, the intermediate tread 100 is formed with fastening protrusions 102 on both sides of its upper and lower sides that are rotated when the tread 100 is rotated, In order to make it run. Of course, if the shaft is rotated and the inclined surface is formed, the stopping plate 102 may not be formed in the tread 100 if the shaft is sufficiently prevented from undergoing the downward force.

The angle of the ramp formed by the axis-rotated tread 100 is about 5 to 40 degrees, and preferably 30 degrees or less. This is because it is difficult to use a wheel chair or a cart when the ramp is steep. The rotation angle of the tread plate 100, that is, the tilt angle of the ramp, can be adjusted by the arrangement position and the interval of the tread 100. Of course, the axis rotation of the tread 100 is made by the angle changing device, and the angle of rotation of the tread 100 at this time is also controlled by the angle changing device.

2 to 4, the support members 110 are respectively positioned at both longitudinal ends of the tread 100 and are manufactured to be fastened to all the shafts 101 of the tread 100. A normal member such as a bearing (not shown) or the like is installed between the support member 110 and the shaft 101 for smooth shaft rotation of the shaft 101 with respect to the support member 110 in the engaged state .

4, the angle regulating member 120 is fixed to a shaft 101 having a predetermined length and one end is formed on one side of the tread 100, and the other end is a chain of a conveyor 140 And is fastened to the belt 144. Accordingly, the other end portion is reciprocated by the chain or the belt 144 to induce the rotation of the shaft 101 fixed to the one end, thereby guiding the tread 100 to rotate the shaft. Further, each angle-regulating member 120 is fixed to each of the shafts 101. Depending on the length of the angle adjusting member 120, the cover 130 may be completely accommodated, or one side may protrude outward.

The angle changing device is a conventional conveyor 140 comprising a power source 141, a switch 142, a wheel 143, a chain or a belt 144. [ When the switch 142 is operated, the conveyor 140 operates to drive the power source 141 to induce reciprocal movement of the chain or belt 144 wound around the two wheels 143. In the present invention, however, the angle adjusting members 120 are mounted on the chain or the belt 144, and the angle adjusting members 120 can reciprocate the same moving distance in the same operation through the reciprocating movement of the chain or the belt 144 . Of course, the reciprocating movement of the chain or belt 144 can be selected in one or the opposite direction through the operation of the switch 142. [

The lid 130 is disposed on both sides of the support member 110 and is a member for protecting the angle changing device, the angle regulating member 120, and the support member 110 from the outside. Since the lid 130 of the lid 130 covers the supporting member 110, the angle adjusting member 120 and the conveyor 140, the lid 130, which covers only the other supporting member 110, Lt; / RTI &gt; size.

<Examples>

6 is a perspective view schematically showing a modified example of the smart step shown in Fig.

The smart step shown in FIG. 6 is compared with FIG. 4 in that the angle regulating member 120 is reciprocated using a link member instead of the conveyor 140, which is an angle changing device, and the other components are the same. Hereinafter, the link member will be mainly described, and other components will be briefly described.

The angle changing device includes a first link member 150, a second link member 151, a cylinder 152, and a switch 142. Here, the switch 142 is the same as or similar to the switch 142 in Fig. 4, so that the description thereof is briefly referred to when necessary. Of course, the lid 130 is installed to receive the first and second link members 150 and 151, the cylinder 152 is selectively accommodated, and the switch 142 may be mounted on the outer surface.

The first link member 150 has a predetermined length and is mounted on one end of the angle adjusting members 120. That is, the first link member 150 is mounted on the opposite end of the one end of the angle adjusting member 120 fixed to the shaft 101 of the tread 100, and the first link member 150 reciprocates, And is provided to rotate the adjusting member 120 axially.

The second link member 151 has a predetermined length and is a member for guiding the reciprocating movement of the first link member 150. Specifically, one end is fastened to the first link member 150, the other end is fastened to the arm 153 of the cylinder 152, the intermediate portion becomes the central axis, and one end portion and the other end portion are axially rotated . Accordingly, when the other end of the arm 153 is moved downward, one end coupled with the first link member 150 moves upward to induce the reciprocating movement of the first link member 150.

Then, the cylinder 152 is actuated by the switch 142 so that the arm 153 reciprocates upward and downward.

 On the other hand, when the angle changing device is the conveyor 140, the lid 130 accommodates the chain or belt 144, the wheel 143, the supporting member and the angle regulating member 120 in the inner space, And the switch 142 can be mounted on the outer surface. Here, one side portion may protrude outward according to the length of the angle adjusting member 120.

Further, when the angle changing device is made up of link members, the first link member 150 and the second link member 151 can be accommodated in the inner space, and in some cases, the cylinder 152 can be accommodated, The switch 142 can be mounted. Here, one side portion may protrude outward according to the length of the second link member 151.
