Marc Blatstein The Problem Every day, all across the globe someone is accidentally dropping something down an elevator shaft, in the space between the car [or cab] & the landing.

1. Elevator Door-Gap Seal
Elevator gap between the car and landing presents an environment where personal items may fall
into the elevator shaft.

The Problem
1) Every day, all across the globe someone is accidentally dropping something down an elevator
shaft, in the space between the car [or cab] & the landing. This is then followed with panic,
followed by its eventual retrieval in some cases for a fee, but always accompanied with a
delayed service call.
2) Who benefits from solving this problem? As the elevator service companies derive part of
their income from servicing these calls, this appears to not be in their interest. Management
Companies who own both commercial and residential buildings can benefit their tenants by
implementing this small fix. Here several things are accomplished, reduced costs with regard to
expensive service calls, zero service call delays as well as creating peace of mind for their
tenants and residents.
The Solution
Key Points:
1) Cheap to produce (already exists in the market, but with modification)
2) One moving part
This is a simple and a very cost effective means to cover the gap. Using the spring version
of an already existing product in the market (the extending & retracting characteristic of
a carpenters measuring tape), this device with its modification becomes a very economical fix.

2. The ‘Tape Container’ with its ‘Free end’ complex can be made into a single or two piece unit.
This allows it to be unclipped & removed when worn out, with a new one to then be easily
reinserted. This very inexpensive fix can save the end user (management companies, owners etc.,
and their tenants), money, and peace of mind by providing a much needed service that has yet to
be fulfilled.
The Figure Description
Fig A1 – G1 shows the elevator door at its almost closed position. For description purposes only
the sliding door (B1 & 2) will be referred to as the male end.
Fig A2 – G2 shows the elevator door at its almost open position. For description purposes only
the sliding door (B1 & 2) will be again referred to as the male end.
Fig B1 Male end, here the door is mostly closed.
Fig B2 Male end, here the door is mostly open.
Fig. C 1&2 (Shows the Tapes Free End attachment location, a devise on the doors male end to
which the Tape Container Free end is attached) identifing the protrusion located on the side of
the door towards the front, but below & behind the sensor strip on the male end to which the
tapes ‘Free End’ is attached.
Fig. D 1&2 (Tape Container) show’s the ‘Tape Container’ which is anchored below & behind
the sensor strip, located on the female end. This is where the material is stored and used to ‘seal
the gap,’ where it retracts into, & where it extends from.
Fig. E 1&2 is meant to represent the approximate 1-2” wide gap separation (the space or distance
that the car/or cab is separated away from the landing). Figures C (the anchoring device that the
Tape Container Free end) & D (Tape Container) are meant to approach, but not physically abut
the front wall that the car/cab rides along.
Fig F1&2; the end wall to which the cars door slides towards as it closes, from here forward

3. known as the female end, and where the Tape Container is found.
Fig. G 1&2 is meant to represent the material used to close the gap, be it a magnetized polymer,
rubber or metal. The material may be able to be stored in a concave like form, only to open up
slightly allowing it to seal the gap. Then with retraction it again is stored in its concave position.
Whatever material is chosen to be used in sealing this gap, it should be considered as illustrative
only of the principles of the invention. Since numerous modifications and changes will readily
occur (to all aspects of the invention described), by those skilled in the art, it is not desired to
limit the invention to the exact construction and operation as shown and described, and,
accordingly, all suitable modifications, materials and equivalents may be resorted
to, falling within the scope of the invention. It should be clear to those skilled in the art that
further embodiments may be made without departing from the scope of the present invention. In
describing a preferred embodiment of the invention illustrated here, specific terminology was
resorted to for the sake of clarity only.
However, the invention is not intended to be limited to the specific terms so selected & described
Here. It is to be understood that each specific term includes all technical equivalents which
operate in a similar manner to accomplish a similar purpose. The foregoing description should be
considered as illustrative only of the principles of the invention.
