A step (hereinafter referred to as a step) 1 for a building provided with a bicycle block according to the present invention is used for connecting the bicycle 80 so that the bicycle 80 can move on a level ground spaced apart from the upper and lower layers of the building. A bicycle block 20, a bicycle block 30 for rotation, a cylinder 40 for rotation, and a lifting portion 50. The cylinder 10, the bicycle block 20,

Specifically, a plurality of treads 2, which connect the upper layer and the lower layer so as to be movable, are provided step by step inside the building, and the wall 3 formed on one side of the tread plates 2 is provided with receiving grooves 3a Is formed.

The drawing cylinder 10 has a rod 11 horizontally installed on a vertical end wall of the receiving groove 3a through a bracket B and a bolt and extending from the inside to the outside or contracting from the outside to the inside. At this time, the drawing cylinder 10 is installed so that the rod 11 can be moved in and out of the outlet 3b of the receiving groove 3a.

A hydraulic cylinder or a pneumatic cylinder can be applied to the drawing cylinder 10, and a supply tank (not shown) for supplying hydraulic or pneumatic pressure to the drawing cylinder 10, (3a).

The bicycle block 20 provides an inclined traveling path through which the bicycle 80 can move up and down. The bicycle block 20 is formed in the shape of a rectangular plate having a predetermined length, width and thickness, And a first side plate 22 which is vertically bent upward at both ends of the first swash plate 21. The first swash plate 21 is a first swash plate 21,

4, the end of the rod 11 of the drawing cylinder 10 is coupled to the left side of the first side plate 22. As shown in Fig.

The rod 11 of the drawing cylinder 10 is drawn out to the outside of the receiving groove 3a when expanding and the first swash plate 21 is seated on the rim of the tread 2 Thereby forming an inclined traveling path in which the bicycle 80 can ascend and descend.

At this time, the drawing cylinder 10 moves the bicycle block 20 to the wall 3 so as to prevent a situation in which the handle of the bicycle 80 is brought into contact with the wall 3 and the bicycle 80 is tilted at an angle, So that the distance is sufficiently long.

When the rod 11 of the drawing cylinder 10 is retracted, the bicycle block 20 is drawn into the receiving groove 3a, but does not interfere with the person who normally goes up and down the stairs 1 So that it is completely drawn into the receiving groove 3a.

In addition, two release-preventing holes 20b are formed on each of the first side plates 22, and one rotation-guiding hole 20a is formed between the release-preventing holes 20b.

The release preventing hole 20b prevents the bicycle block 30 from moving out of the bicycle block 20 when the bicycle block 30 rotates upward and downward, The separation preventing hole 20b and the rotation guide hole 20a will be described in more detail later than the description of the connecting portion 60. [

The turning bicycle block 30 provides an inclined traveling path in which the bicycle 80 can move up and down together with the bicycle block 20. The bicycle block 30 has a rectangular plate shape having a predetermined length, And contacts the bottom surface of the receiving groove 3a to maintain a predetermined inclination angle.

The lower side of the turning bicycle block 30 is connected to the first side plate 22 via the connecting portion 60 in a state in which the lower side is seated on the upper side of the upper end of the first swash plate 21 constituting the bicycle block 20, And can be rotated in the upward and downward directions.

At this time, the lower side of the turning bicycle block 30 which is seated on the upper end of the upper end of the first swash plate 21 is bent in a " So that the bottom surface of the base member has a step-free contact structure.

In addition, an inclined surface 311 for allowing the bicycle 80 to easily move from the first side plate 22 to the turning bicycle block 30 is provided below the bent portion of the turning bicycle block 30, And is formed to be inclined downward toward the side plate (22).

Subsequently, on both sides of the bent portion of the turning bicycle block 30, a circular bar shape (not shown) is provided for raising and lowering the turning bicycle block 30 in the turning guide hole 20a so that the turning bicycle block 30 can be rotated in the upward and downward directions And the pivot shaft 312 is formed to protrude in the horizontal direction.

The connecting portions 60 are installed in the outer circumferences of the pivot shafts 312 so as to be vertically movable with the pivot shafts 312 in the pivoting guide holes 20a And an escape prevention tube 62 which is lifted and lowered in the escape prevention hole 20b when the mounting tube 61 is mounted on the rotary shaft 312. [

That is, the bicycle block 20 and the turning bicycle block 30 are connected to each other via a connecting portion 60. The turning bicycle block 30 is connected to the rod 11 of the drawing cylinder 10 When the bicycle block 20 is extended, the bicycle block 20 is drawn out to the outside of the receiving groove 3a and is mounted on the rim of the treads 2, thereby forming an inclined auxiliary traveling path in which the bicycle 80 can be moved up and down .

When the bicycle block 30 is drawn out to the outside of the receiving groove 3a, the upper side of the bicycle block 30 faces the horizontal plane 2a of the tread 2 positioned at the uppermost position, The bicycle 80 can be easily moved to the upper layer sequentially through the bicycle block 20 and the turning bicycle block 30. [

In addition, the rotation guide hole 20a is formed in an upper opening shape, and the release prevention hole 20b is formed in a rectangular shape having upper, lower, left, and right sides closed. Therefore, when the connecting portion 60 is raised by the rotating cylinder 40 to be described later and the lower side of the turning bicycle block 30 is rotated upward, the separation preventing pipe 62 is separated from the separation preventing hole 20b So that the pivot shaft 312 is not separated from the pivot guide hole 20a.

The pivoting cylinder 40 converts the inclination angle of the turning bicycle block 30 so as to be gentle so that the bicycle 80 can be easily moved to the upper layer. And a rod 41 fixed to the upper surface of the body 23 and extending outwardly from the inside or contracting from the outside to the inside.

At this time, the rotating cylinder 40 may be a hydraulic cylinder or a pneumatic cylinder, and is designed to receive hydraulic pressure or pneumatic pressure from the supply tank.

Then, the rotating cylinder 40 is completely drawn into the receiving groove 3a so as not to disturb the people who normally move up and down the stairs 1.

The rod 41 of the rotating cylinder 40 is installed on one side of the connecting portion 60. When the rotating bicycle block 30 is drawn out to the outside of the receiving groove 3a, Thereby rotating the lower side of the main body 30 upward. In this case, as the upper side of the turning bicycle block 30 is rotated downward and becomes closer to the horizontal surface 2a of the tread 2 positioned at the uppermost position, the inclination angle of the turning bicycle block 30 becomes gentle .

Therefore, when the bicycle 80 positioned in the turning bicycle block 30 is moved to the tread 2 positioned at the uppermost position, it is possible to easily move the bicycle 80 while preventing a great impact on the wheel of the bicycle 80 have.

The lifting portion 50 is installed on the upper and lower layers of the building and pulls the bicycle 80 positioned in the bicycle block 20 to the upper layer of the building. The motor 51, the drum 52, A wire 53, a rolling portion 54, a band 55, a descending rail 56, and a limit switch 57.

The motor 51 is installed in all the layers except for the lowermost layer of the building to provide power for lifting the bicycle 80, and a known AC motor 51 or DC motor 51 is applied.

At this time, the axis of the motor 51 is rotated in the forward or reverse direction so that the drum 51 can be selectively rotated according to the rotation direction.

The motor 51 is installed on the upper surface of the receiving portion 90 formed in a rectangular box shape so that a wire 53 described later will not contact the bottom surface of the building or the tread 2.

At this time, although not shown in the drawing, the motor 51 may be installed on the wall 3 so as to be separated from the floor surface through a separate bracket (not shown) instead of the receiving unit 90.

The outer surface of the drum 52 facing the motor 51 is coupled to the shaft of the motor 51 and rotated in the forward or reverse direction together with the axis of the motor 51.

The wire 53 transmits the power of the motor 51 to the bicycle 80, and one side thereof is fixed to the drum 52. The wire 53 is wound on the drum 52 when the motor shaft of the motor 51 is rotated in the direction of the upper layer (hereinafter referred to as the "forward direction") and is wound in the lower layer direction The drum 52 is rotated.

At this time, the wire 53 is used with sufficient rigidity and durability to sufficiently support the load of the bicycle 80.

The rolling part 54 moves the band 55 to be described later from the upper layer to the lower layer of the building and includes a rotating shaft 541, the rotating shaft 541, a roller (not shown) mounted on both sides of the rotating shaft 541 543, and a connecting shaft 542 extending in the horizontal direction at a central portion of the rotating shaft 541.

The band 55 is mounted on the handle frame 81 of the bicycle 80 and is connected to the connecting shaft 542 at a central portion thereof to be movable together with the rolling unit 54.

The band 55 is made of a material having elasticity, and the inner side surface of the band 55 and the outer side surface of the other side are formed with the valve rods 55a and 55b, respectively. Therefore, the band 55 can be easily mounted regardless of the diameter of the handle frame 81. [

When the band 55 is mounted on the handle frame 81 of the bicycle 80 located in the bicycle block 20 in the lower layer of the building and then the motor 51 is operated so that the motor shaft is rotated in the forward direction, The wire 53 is wound around the drum 52 to pull the bicycle 80 to move the bicycle 80 to the upper layer of the building along the bicycle block 20 and the turning bicycle block 30. [

The lower rail 56 is used to move the band 55 which has moved to the upper layer of the building to the lower layer so that it can be used by the next user. The lower rail 56 is disposed obliquely to the side wall W, A second swash plate 561 spaced apart from the first swash plate 561 and a second side plate 562 bent upward from both sides of the second swash plate 561 and fixed to the side wall.

That is, the rollers 543 and the band 55 coupled thereto are placed on the upper surface of the second swash plate 561 in the upper layer of the building, and then the motor 51 is operated so that the motor shaft is rotated in the reverse direction, The roller 543 is moved along the second swash plate 561 so that the band 55 is moved to the lower layer of the building and the second side plate 562 is rotated by the roller 543 and the band 55 do not fall into the tread 2 during the movement.

In addition, a limit switch 57 for stopping the operation of the motor 51 and preventing the wire 53 from being released when the band 55 contacts the lower end of the lower rail 56 is further installed .

Hereinafter, the operation of a staircase for a building provided with the bicycle block 20 according to the present invention will be described.

A switch S1 for operating the drawing cylinder 10 to extend or contract the rod 11 and a switch S2 for controlling the operation of the motor 51 are provided on the lower side wall W of the building And a switch S3 for operating the drawing cylinder 10 to expand or contract the rod 11 and a switch S4 for controlling the operation of the motor 51 are provided in the upper layer.

When the bicycle user wishes to climb the stairs 1 together with the bicycle 80, the user pushes the switch S1 so that the rod 11 of the drawing cylinder 10 is expanded. In this case, the bicycle block 20 and the turning bicycle block 30 are drawn out from the receiving grooves 3a and are seated on the upper surfaces of the treads 2, so that a ramp, on which the bicycle 80 can move, And an auxiliary ramp are formed.

The user then mounts the band 55 positioned on the lower layer on the handle frame 81 of the bicycle 80 and then places the bicycle 80 on the upper surface of the first inclined plate 21 of the bicycle block 20 Press switch S2.

When the switch S2 is pressed, the motor shaft is rotated in the forward direction and the wire 53 is wound on the drum 52, so that the bicycle 80 located in the lower layer of the building is rotated by the bicycle block 20, The bicycle 80 can be easily moved from the lower layer to the upper layer of the building as well as the ordinary adult as well as the elderly person or child who is relatively weak.

A sensor 70 is installed on the rotating bicycle block 30. The sensor 70 may be exposed to the top surface of the bicycle block 30 so as to contact the front wheel of the bicycle 80. [ Therefore, when the front wheel of the bicycle 80 touches the sensor 70, the sensor 70 senses the front wheel and transmits a signal to a controller (not shown) electrically connected thereto. The controller 70 receives the signal transmitted from the sensor 70 So that the rod 41 of the rotating cylinder 40 is expanded.

In this case, as the lower side of the turning bicycle block 30 is rotated upward and the upper side thereof is rotated downward to be close to the horizontal surface 2a of the tread 2 positioned at the uppermost position, It is possible to prevent a great impact on the wheel of the bicycle 80 in the process of moving the bicycle 80 to the tread 2 located at the uppermost position of the bicycle 80.

When the sensor 70 does not sense the front wheel of the bicycle 80, the sensor 70 transmits a signal to the control unit so that the rod 41 of the rotating cylinder 40 is contracted so that the turning bicycle block 30 Return to the original state.

After the bicycle 80 is moved to the upper layer of the building, the band 55 is removed from the handle frame 81 and placed on the second side plate 562 of the lower rail 56, The band 55 and the rolling portion 54 may be moved to the lower layer again by operating the motor 51 so that the motor shaft is rotated in the reverse direction.

When the user of the next bicycle 80 is not present in the lower layer of the building, the switch S3 is pressed to shrink the rod 11 of the drawing cylinder 10 so that the bicycle block 20 and the turning bicycle block 30 are retracted. So that it does not interfere with the general people using the stairs (1).

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, Of the right.
