In addition, the seat 100 exists as a weight and can balance the balance weight (not shown) of the elevator to reduce the load upon driving.

That is, the elevator car 10 ascends and descends in balance with the counterbalance, and when there is no occupant, or when the difference between the counterweight and the counterbalance weight (relatively light) is large, a load due to traction of the elevator car 10 largely occurs, The present invention can reduce the weight ratio of the elevator car 10 and the counter weight to minimize the power loss by using the seat 100 as a weighing machine because there is a problem that it leads to power consumption and economic loss due to maintenance of the elevator. Respectively.

The seat 100 is provided with a pair of supports 110, a seating portion 120 rotatably coupled to the supporting rods 110, a coupling portion between the supporting rods 110 and the seating portions 120, A stopper 130 for restricting the turning radius of the seating portion 120 and a cylinder 170 elastically supporting the rotation of the seating portion 120 and the seating portion 120. Hereinafter, do.

FIG. 3 is an exploded perspective view of a seating part according to a preferred embodiment of the present invention, FIG. 4 is a view illustrating the separation of the support, FIG. 5 is a view showing the separation of the stopper, and FIG.

As shown in the figure, the support 110, the stopper 130 and the cylinder 170 having the same structure are symmetrically disposed with the seating part 120 therebetween, and the symmetric structure is represented by a and b.

However, since each of the configurations a and b has the same configuration symmetrical to each other, description of (a, b) will be omitted as one component.

The seating part 120 includes a rotation shaft 121 detachably joined to the stopper 130, a rotation bracket 125 coupled to the rotation shaft 121 and rotated together with the rotation shaft 121, And a seat panel 127 coupled to the rotary shaft 121 through the seat panel 125 and seating the passengers.

The rotation shaft 121 is a round bar and has connection protrusions 123 for axial coupling with the stopper 130 at both ends in the longitudinal direction. The connection protrusions 123 are polygonal Preferably, but not exclusively, all shapes other than the circle, as well as the polygon, may be present in the power transmission element.

At this time, it is preferable that the key is integrally formed as shown in the outer circumferential surface of the rotation shaft 121, but it is not limited thereto, and a key groove may be formed, and a separate key may exist as an independent element.

In the present invention, the coupling pin 140, which will be described later, is used as a shaft coupling member. In the present invention, And a description thereof will be given later.

The rotation bracket 125 is coupled with the rotation shaft 121 at a predetermined interval between both ends of the rotation shaft so as to rotate together with the rotation shaft 121. The engagement of the seat panel 127 and the rotation shaft 121, .

The rotation bracket 125 is key-engaged with the rotation shaft 121 and is coupled to the seat panel 127 through a normal fastening means (e.g., a screw or a bolt).

The seat panel 127 is preferably made of a metallic sheet to prevent the generation of harmful substances in the event of a fire, but a pad made of a nonflammable material may be used together with the metal to improve a seating feeling (cushioning feeling).

The support frame 110 has a structure in which one side and both sides of the elevator car facing the inner wall are closed. A guide groove 113 for coupling the stopper 130 is formed on the support panel 111, At least one reinforcing panel 115 is further provided between the upper and lower ends to maintain the space of the supporting panel 111.

The guide groove 113 is in the form of an inverted-shaped groove as shown in the figure. The stopper 130 is engaged with the support 110 through the guide groove 113.

That is, the stopper 130, which is axially coupled to the seating unit 120, is accommodated in a vertically movable manner so as to be vertically movable. The stopper 130 is resiliently supported by the cylinder 170, It is possible to cope with it. Therefore, when the seat portion moves up and down due to a sudden shock, the shock is damped, and the inconvenience caused by the shock can be minimized.

Here, the impact is the load caused by the seating of the passenger or the flow caused by the movement of the elevator car 10 or the flow caused by the internal passenger.

It is preferable that the reinforcing panel 115 is provided in the vicinity of and below the guide groove 113 to which the stopper 130 is coupled. At this time, the cylinder bracket 119 is installed through the reinforcing panel 115 installed at the lower part as shown in the figure.

The stopper 130 includes an engaging pin 140 which is axially coupled to the rotating shaft 121 and rotates together with the rotating shaft 121 in the axial direction and whose other end is engaged with the supporting table 110 through the guide groove 113, The rotation radius of the rotation cam 150 and the rotation cam 150 coupled to the outer periphery of the other end of the fin 140 and rotated together with the engagement pin 140 may be limited so that the seating panel 127 is perpendicular And a fixing bracket 160 that is parallel to and parallel to each other.

The coupling pin 140 has a first pin 141 having one end and a coupling groove 145 corresponding to the coupling protrusion 123 protruding from the end of the rotation shaft 121. The coupling pin 140 has a smaller diameter than the first pin 141, And a second pin 147, which forms the other end of the coupling pin 140 as an extension body and has a rotation cam 150 coupled to an outer periphery thereof.
