[0022] FIG. 1 shows a technician carrying all elements of the barrier system (100) on his shoulder. An adjustable shoulder strap (102) is fitted through a carrying strap attachment guide (112). The adjustable shoulder strap (102) is provided with self-locking loops at the ends (103) (not shown here). Also attached is a storage bag (104) containing accessories. The storage bag (104) is held in place by the adjustable strap (102). Latching connectors or Tabs (110) are located at the ends and exterior midsection of the panels (101). The latching connector tabs (110) are oriented opposite to their corresponding reciprocal tab (110). The technician may carry multiple panels (101) simultaneously, allowing him to adjust the size of the barrier desired. Carrying handle receptacles (106) are located at the midsection of panels (101) for allowing the technician to grasp and move the orientation of the panel (101).
[0023] With respect to FIG. 2, in a preferred embodiment, the contents of the storage bag (104) are illustrated. Two suctions cups (118) with handles (119) are used for attaching to end walls surrounding the elevator entrance (126). Two hook and loop straps (116) are also included and used for attachment purposes. Two ratchet lanyard hooks (132) are included for tightening the barrier system (100) to the suction cups (118). A ratchet-type tensioning mechanism (108) having at one end a cord engaged radially around a sheave in the ratchet-type mechanism (108). The other end of the cord having a loop (136) tied by a knot (138), the cord running through a sheave located in the ratchet-type tension mechanism (108) having a wheel with a groove for a rope to run on, as in a pulley block. The other end of the cord (122) not attached, used for pulling tight the ratcheting tension mechanism (108).
[0024] FIG. 3 shows a plurality of panels (101) used in forming the barrier system (100). Latching connectors or tabs (110) are provided along vertical side ends (103) and (105) of the panels (101) for attaching the panels to each other, as needed. Latching connectors (110) are seen to be in the form of outstanding tabs (110) which are spaced laterally of the panels side ends (103) and (105) which are oppositely directioned along the opposite sides of the panels (101), forming openings (124) between the panel side edges (103, 105) and the corresponding tabs (110) into which oppositely disposed tabs (110) from an adjacent panel (101) engage, as illustrated. Carrying handle receptacles (106) are illustrated at the exterior of the mid-section of panels (101).
[0025] With respect to FIG. 4 the latching procedure for engaging the panels (101) of the barrier system (100) is shown, using the latching connectors (110) as described with reference to FIG. 3. The carrying handle receptacles (106), carrying strap attachment guide (112) and openings (124) help provide airflow characteristics. When the panels are assembled together they acquire the ability to stand vertically.
[0026] With respect to FIG. 5 a fully assembled barrier system (100) is depicted properly deployed around an elevator door (126). Its Latching connectors (110) are connected by the oppositely disposed tabs of the adjacent panel (101). The carrying handle receptacles (106) are used to position the panels (101) in their proper orientation. The carrying strap guides (112) along with openings (124) permits partial viewing of enclosed area.
[0027] With respect to FIG. 6 the ratchet lanyard (120) covered by hand, with one end of a chocked rope (136) at one end and a hook (132) at the other end are shown indicating how it is looped through the carrying handle receptacle (106) prior to attaching the hook (132) to the suction cups (not shown). The end of the rope (122) is used to tighten and secure the panel (101) so that the hook that is attached to the suction cup will attach to the adjacent walls. Opening (124) and the carrying strap attachment guide (112) helps the airflow to flow reducing resistance to the panels (101) while permitting viewing to take place.
[0028] With respect to FIG. 7 the ratchet lanyard (120) with its hook (132) are shown in their pulling position. When the end of rope (122) is pulled through the ratcheting feature of the lanyard (120) it pulls the barrier (101) closer to the elevator entrance (126) not shown, and provides a barrier, isolating the elevator door (126) from access. Opening (124) and carrying strap attachment guide (112) provide airflow through the panels helping to stabilize the panels from falling. A new loop (128) is formed around the inside of the latching connector tabs (110)
[0029] With respect to FIG. 8, a first suction cup (118) and handle (119) are depicted attached to a surface or wall (121) surrounding the elevator entrance door (126). When the rope end (122) is pulled by hand through opening (124) the ratcheting feature continues pulling the barrier panel (101) closer to the wall (121) eliminating a path for a person or even a child to bypass the barrier system (100). Latching connector tabs (110) are pulled closer to the elevator (121) by the tension created by the new rope on the tension mechanism (108). The new loop (128) secures panel (101) to the rope and suction cup (118). The attachment strap attachment guide 112, the carrying handle receptacle (106) and openings (124) allow air to pass through the panels (101) reducing the pressure against them.
[0030] With respect to FIG. 9 a second opposite suction cup (118) is shown attached to an opposite wall (121). While one suction cup (118) is inside the elevator entrance door (126) protected from being accessed, the second suction cup (118) shown here is facing outside the barrier (100).
