Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an impact reinforcement for an elevator platform door,

The present invention relates to a conventional elevator landing door reinforcing material that is not reinforced. More specifically, a reinforcing material of a folding structure is installed inside a conventional elevator landing door so that the impact applied through the door is dispersed And more particularly, to a stiffener for an elevator platform door that prevents a safety accident caused by a door being damaged or damaged.

Generally, an elevator is installed in a high-rise building and is vertically descending.

Such an elevator is mounted through a platform provided on each floor, and the platform is configured to be kept closed by a platform door to prevent a safety accident and to be opened only when the platform reaches the corresponding floor.

However, the conventional landing door may be damaged by the impact, so that the elevator door may be opened even if the elevator is not in the layer due to the damage.

Accordingly, various types of reinforcement are performed for the platform door, among which the door shoe is most reinforced. For example, the safety structure of the elevator platform door has been registered in Korean Patent No. 10-0901733.

Conventionally, in a door structure in which a door shoe of a landing door is coupled to a rail of an elevator landing door frame, the rail of the door frame is gradually widened from the upper side to the lower side to have a trapezoidal shape A door shoe coupled to the door is formed of a first door shoe and a second door shoe so as to have a trapezoidal shape gradually widened from the upper side to the lower side so as to be in contact with the shape of the rail, And a coupling hole is formed on the upper side of the first door shoe and the second door shoe to form a coupling hole for coupling with the reinforcing bar of the door. It is possible to prevent the pedestrian door from easily separating from the door frame, thereby reducing the risk of personal injury. He said, when combining the landing door and the door frame, and that is also made of the desired sliding without noise even if a slight error occurs not occur on the objects and effects of the invention.

However, it is somewhat difficult to prevent the shock applied to the door and the damage caused by the door shoe alone. If an external impact is applied, the impact is transmitted to the door shoe through the door without any buffering action, which may cause damage to the door as well as damage to the door.

Accordingly, door doors for reinforcing the doors themselves have been produced with door shoe. For example, an elevator landing door has been registered as an elevator door which has complemented the escape prevention structure of Korean Patent No. 10-1249751.

Such a conventional elevator landing door has a reinforcing bar which is horizontally thicker and thicker than the door panel and which is thicker than the door panel so as to further strengthen the self-strength of the door panel, Respectively.

However, the conventional landing door can be applied to door manufacturing. In particular, as described in claim 6, since the installation conditions and construction of the reinforcing panel and the reinforcing bar are limited, it is not easy to apply the existing landing door.

Korean Patent No. 10-0901733 Korean Patent No. 10-1249751

It is an object of the present invention to provide an elevator landing door stiffener that can be easily reinforced with respect to an elevator landing door that has not been previously reinforced.

It is another object of the present invention to provide a stiffener in which a first reinforcing rod and a second reinforcing rod are hinged to each other to expand and contract a volume, So that it can be mounted on the door only by the elevator.

It is a still further object of the present invention to provide a door for a door, which has a width equal to the length of the first reinforcing rod, as well as a door having a short width, because the reinforcing member is foldably installed around the hinge, So that the reinforcing rod and the second reinforcing rod can be folded and installed on the door.

It is still another object of the present invention to provide an elevator landing door stiffener in which the stiffness of the elevator landing door can be more firmly ensured by allowing the impact to be dispersed not only on the first reinforcing rod but also on the second reinforcing rod.

In order to achieve the above object, the present invention provides an elevator door stiffener comprising: a first reinforcing rod installed inside the door vertically or horizontally at a position where an impact is expected to occur in the door; And a pair of second reinforcing rods disposed at both ends of the first reinforcing rod to disperse an impact transmitted through the first reinforcing rod, wherein the first reinforcing rod and the second reinforcing rod are hinged , And a door stiffener for an elevator car platform, which is fastened to each other so as to be foldable to each other.

It is preferable that the first reinforcing rod is a metal tube having a cross section of any one of a circle, a square, a rectangle, and a polygon.

It is preferable that the second reinforcing rod is any one of metal tubes selected from a circle, a square, a rectangle, and a polygon, or a shape steel.

The second reinforcing rod may have a width corresponding to the inside of the bent portion formed at both ends of the door so that the impact applied to the door together with the bent portion is dispersed and supported.

The reinforcing member is hinged to the first reinforcing rod in the center region between the opposite ends of the second reinforcing rod and extends in the H-shape in the left / right direction or the up / down direction when rotated about the hinge, And it is preferable to be constructed so that it can be folded and reduced in volume.

It is preferable that the second reinforcing rod is formed as a long hole, and the first reinforcing rod is movably installed along the long hole.

According to the embodiment of the present invention, an elevator landing door that has not been reinforced in the past can be reinforced, so that at least a safety accident due to door damage can be prevented.

In addition, since the first reinforcing rod and the second reinforcing rod are hinge-coupled to each other, the volume can be expanded and reduced, thereby reducing the volume by folding, thereby minimizing the peripheral interference and facilitating the loading. It can reduce the economic burden and improve the product competitiveness.

Further, since the reinforcing member is provided foldably around the hinge, the reinforcing member can be folded and folded so that the door can be installed in a door standard having a width equal to or shorter than that of the first reinforcing rod, Can be unified or minimized, so that the effect of improving the competitiveness of the product in mass production can be expected.

At least one side of the first reinforcing rod 110 facing the door is preferably closely attached to the door so as to support the shock transmitted through the door 20. [

The second reinforcing rod 120 includes a first rod 121 installed at one end of the first reinforcing rod 110 and a second rod 123 installed at the other end of the first reinforcing rod 110. The first rod 121 and the second rod 123 A second fastening hole 125 is formed in the center region between both ends of the rod 123 to fasten the hinge 130 and is rotatable with respect to the first reinforcing rod 110 through the hinge 130 .

The second reinforcing rod 120 may have the same cross-section as the first reinforcing rod 110 as shown in Figs. 4A to 4D, or may be a steel such as Figs. 4E and 4F. At this time, it is preferable that the width W of the second reinforcing rod 120 corresponds to the width W of the bent portion 21. This is because the impact applied to the first reinforcing rod 110 is dispersed through the second reinforcing rod 120 and the dispersed impact is applied to the door so as to be relaxed through the bent portion 21, Should be maintained. Therefore, it is preferable that the second reinforcing rod 120 and the bent portion 21 have corresponding widths. Here, FIG. 4E is a C-shaped steel, and f indicates an equilateral or diagonal-shaped steel.

3, the hinge 130 is not limited to a pin shape as shown in FIG. 3, but it is not limited thereto, and may be a hinge shape, which is a typical structure. .
