Abstract
This new mechanical device is used for elevator door sills to keep clean from dirt using a rubber motor belt. It is done by a rubber motor belt sliding in and out of the sill covering the door sill when the elevator car door is open.
Description
Elevator Door Sill Protector This invention applies to the elevator industry. Minimizing wear and tear for single speed elevator doors and two speed elevator doors.
Background Information This mechanical device is designed to prevent elevator doors from getting stuck in the elevator door sill, because of dirt build up or other small objects such as coins or keys being wedge in the guide bars for an elevator door. This will cause the door to stop while opening or closing and in some instances, may cause the door to leave its track. This results in the elevator being unavailable to vertically transport individuals and goods. Elevator maintenance companies will be required to send an elevator technician to site to remedy a simple problem. Building owners will experience avoidable elevator downtime and expensive call back charges. The door operator may incur permanent damage with frequent derailment. The Elevator Door Sill Protector is designed to minimize these disruptions by placing a cover in the elevator door sill which moves with the door not allowing anything in the sill to interfere with the guide bars for an elevator door.
There is no present mechanical device which shares the same practice as this invention in the elevator industry in Canada.
Drawings Figures Figure 1- Side view of how the operations is applied under the elevator car Summary of the Invention A 1/2" wide rubber motor belt is attached to the bottom of the door, using a small L bracket attached by self tapping screws on both the door and the belt. Which then the rubber motor belt goes through a 1/2" rope thimble at the end of the elevator door sill into a 1" diameter EMT held up under the elevator car using 1" EMT clips or a piece of 1/4"- I" wide unistrut is attached under the elevator car using special unistrut clips and a bolt going through the beam located underneath the elevator car. At the end of the rubber motor belt is an S clip which is attached directly to the rubber motor belt. The S clip is then attached to a hook and eye turnbuckle with the S clip being attached to the eye hole.

At the end of the rubber motor belt is an S clip which is attached directly to the rubber motor belt. The S clip is then attached to a hook and eye turnbuckle with the S clip being attached to the eye hole.
2 The hook and eye turnbuckle is attached to a specially designed spring so that the rubber belt does not get damaged or get caught on anything in the elevator shaft. The mechanical device is secured under the elevator car with 2 L brackets which are attached together by nuts and bolts. The brackets are attached underneath the elevator car using self tapping screws or nuts and bolts (this depends on how thick the metal is underneath the elevator car). This invention can be used on both single speed and two speed elevator doors.
