Description

Platform for elevators where door seals can be easily replaced {ELEVATOR PLATFORM WITH EASILY REPLACEABLE HALL DOOR SILL}

The present invention relates to a platform for an elevator that allows easy replacement of platform door seals.

Generally, elevators are installed in high-rise buildings to transport passengers or cargo up and down using power. Additionally, a platform is installed on each floor of the building to board and disembark passengers and cargo from elevator cars that move up and down.

The platform includes an elevator door, a door sill, and a jamb, and the door sill is installed horizontally on the bottom of the elevator door. The lift door opens and closes the entrance by sliding along the door sill through a plurality of door shoes whose lower ends are slidingly coupled to the guide groove portion of the door sill.

Meanwhile, elevators are installed and used in advance before the building is completed to transport construction materials during the finishing work of each floor. Therefore, when transporting construction materials using an elevator, scratches, wear, or damage can easily occur on the surface of the door seal exposed to the outside, so it must be replaced with a new product after the building is completed.

In the past, the three-way frame and the door seal were directly connected through bolts, and when replacing the door seal, there was a problem that the door seal could only be replaced by dismantling the three-way frame and the already constructed building finish. Accordingly, the cost and time to replace the door seal increased, and the industrial waste generated as the building was dismantled increased, causing environmental pollution.

The purpose of the present invention is to solve the above problems, and to provide a platform for an elevator that can easily replace the door seal installed on the platform without removing the three-way frame.

However, the technical challenges that this embodiment aims to achieve are not limited to the technical challenges described above, and there may be other technical challenges.

As a technical means for achieving the above-described technical problem, the elevator platform for easy replacement of the platform door seal according to an embodiment of the present invention includes a seal bracket fixed to the ridge of the building floor; A door sill fixed to the upper part of the sill bracket; A lifting door slidably coupled to the door seal; A three-way frame (jamb) installed on the upper part of the building floor parallel to the lifting door; a fixing bracket fixed to the lower part of the three-way frame and formed in a fastening groove recessed from the side at one end; and a first fastening member inserted into the fastening groove to secure the door seal to the bracket. At this time, the fixing bracket is fixed to the three-way frame in close contact with its outer circumference, one side of which protrudes outward from the three-way frame, the fastening groove is formed in the protruding part, and the first fastening member is used to fasten the fastener. It is fastened by sliding into the groove from the side.

According to an embodiment of the present invention, the door seal can be easily replaced without removing the three-way frame, which has the effect of reducing replacement time and cost. Additionally, this configuration has the effect of saving construction and labor costs.
