1N VEN TOR.
BY W -Maw United States Patent F 3,240,926 ELEVATOR ANTI-TRIP LIGHT Francis A. Hajnik, 130 Kartes St., Johnstown, Pa. Filed Apr. 3, 1964, Ser. No. 357,080 7 Claims. (Cl. 2402) This invention relates to a novel and useful elevator anti-trip light and more specifically to an apparatus designed primarily for the purpose of providing an illuminated area immediately adjacent the edge portion of the floor of an elevator defining the lower extremity of the ingressfand egress opening therein for receiving and discharging passengers therethrough.
While it is seldom that a person entering or leaving an elevator finds it difficult to be sure of his footing if the floor of the elevator is substantially coplanar with the adjacent flooring of the building in which the elevator is disposed, should the elevator floor be even slightly out of horizontal alignment with the adjacent flooring of the building, a passenger entering or leaving the elevator may experience difficulty in having to suddenly adjust to the different elevation of the flooring on which he is supported.
This sudden unexpected adjustment demand which is experienced by a large percentage of the people who ride elevators can cause an elevator passenger to lose his footing and fall. Further, even though the floor of an elevator may be coplanar with the adjacent flooring of-the building in which. the elevator is disposed, past experience sometimes causes elevator passengers to suddenly remember a previous fall which can result in the passenger becoming unsure of his footing and to fall even though the flooring of the elevator may be coplanar with the adjacent floor of the building.
It is accordingly the main object of this invention to provide an elevator anti-trip light of the type including means for forming an illuminated strip at the edge of an elevator floor defining the lower limit of the doorway formed in the elevator in order that passengers may be visually forewarned if the elevator floor is not coplanar with the adjacent building flooring.
A further object of this invention, in accordance with the immediately preceding object, is to provide an elevator anti-trip light which will call an elevator passengers attention to the edge of the flooring of the elevator defining the lower limit of the doorway opening in the elevator even though the elevator flooring may be coplanar with the adjacent fiooring of the building in which the elevator is disposed in order that the elevator passengers may feel confident of their footing as they enter and depart from the elevator.
Still another object of this invention is to provide an elevator anti-trip light constructed in a manner whereby it may be readily secured to existing elevators as an attachment therefor.
A further object ofthis invention is to provide an elevator anti-trip light constructed in a manner whereby it is adapted for securement to'substantially all types of elevators.
A final object, of this invention to be specifically enu-' accompanying drawing forming a part hereof, wherein like numerals refer to like parts throughout, and in'which:
FIGURE 1 is a fragmentary perspective view of a conventional form of elevator shown with the elevator antitrip light mounted thereon; 4
FIGURE 2 is a horizontal sectional View of the elevator anti-trip light taken substantially upon a plane passing along the upper surface of the lower portion of the housing for the light source of the anti-trip light;
FIGURE .3 is a fragmentary wertical sectional view taken substantially upon a plane passing through the center of the anti-trip light and the associated elevator with the elevator shown positioned in horizontal alignment with a floor construction of a building; and
FIGURE 4 is a perspective view of a replaceable portion of the anti-trip light.
Referring now more specifically to the drawings the numeral 10 generally designates a conventional form of elevator which includes a floor 14 and one upstanding side wall 16 having an opening 18 formed therein whose lower extremity is defined by the upper surface of the floor or flooring 14.
From FIGURE 3 of the drawings it may be seen that the elevator 10 may be operated so as to horizontally align the upper surface of the floor 14 with the upper surface of an adjacent floor 20 of a building in which the elevator 10 is disposed.
' The elevator anti-trip light of the instant invention is generally referred to by the reference numeral 22 and includes a light source enclosing housing generally referred to by the reference numeral 24. The housing 24 is tubular and includes upper and lower halves 26 and 28 which aresecured together in any convenient manner such as by fasteners 30. A pair of depending mounting brackets 32 are supported from the lower surface 34 of the flooring 14 in any convenient manner such as by fasteners 36 and include laterally directed support flanges opening notch 42 formed in the front side wall 44 thereof.
One end of an elongated panel 46 is secured in the notch 42and clampingly engaged between the confronting surfaces of the upper and lower halves 26 and 28 of the housing 24 between which the panel 46 is received. The
Although the panel 46 could be made of sufiicient length so as to project upwardly to a point substantially horizontally aligned with the upper surface of the floor 14, inasmuch as such an elevated upper end edge of the panel 46 would be continuously marred by persons walking thereon when entering or leaving the elevator the panel 46 terminates at its end edge 56 below the upper surface of the floor 14. However, a transparent extension strip 58 is provided and is secured to the edge or face 50 in any convenient manner such as by fasteners 60 and includes a lower edge portion 62 which is in vertical alignment with the upper edge portion 56 and receives light rays emitting from the edge portion 56. Therefore, the extension strip 58 forms an extension of, the panel 46 which may be readily replaced as its upper edge 64 becomes overly scarred by persons stepping thereon when entering or leaving the elevator 10.
As can best be seen from FIGURE 2 of the drawings the upper half 26 of the housing 24 may be removed so as to expose the illuminating tube-40 in order that the latter may be cleaned or replaced as desired.
The foregoing is considered as'illustrative'onlyof the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordinglyall suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
