Title: Tether for use with autistic children

Description:
BACKGROUND OF THE INVENTION 
     The present invention pertains generally to a device for assisting disabled children diagnosed as being autistic. 
     Such children are introverted to the extreme and may be helped by persons trained in promoting conversation with the child. 
     It has been determined that such interchanges can be fostered by mutual casual conversations about random objects viewed during a walk in an area of interest such as a park, garden, zoo, etc. Such conversations are promoted by the proximity of the adult and the autistic person and hindered by the separation of same. 
     U.S. Pat. No. 6,675,742 shows a leash with a series of grommets selectively receiving end mounted snaps to vary the effective length of the leash. 
     U.S. Pat. No. 4,667,624 discloses a harness to join an adult and child with an adjustable strap. Both have a waistband with snap hooks for attachment to the adult&#39;s waistband and to a harness on the child. 
     BRIEF SUMMARY OF THE INVENTION 
     The invention is disclosed as including a tether between at least two persons. The tether is provided with a release feature permitting the autistic person to experience separation loss of association and hence loss of a conversation with the adult. Reestablishment of the tether connection appears to have a positive effect on the desire to communicate or resume the earlier side by side relationship. 
     The term child is used presently to identify a person experiencing autism, usually a person of pre-adult age. 
     A release feature of the tether is responsive to tensioning with tether separation occurring, after opening of a fabric closure component. The gradual displacement of a tether a tether attached ring provides an audible indication, to the child, of impending detachment from the adult. A secondary release provides increased, retention of a tether D-ring when required. 
    
    
     
       BRIEF DESCRIPTION OF THE DRAWING 
       In the drawing: 
         FIG. 1  is a view of the tether in use, 
         FIG. 2  is a fragmentary plan view of the tether; 
         FIG. 3  is a fragmentary plan as a modified tether; 
         FIG. 4  is an elevational view of a retainer on a belt fragment; 
     
    
    
     DETAILED DESCRIPTION OF THE INVENTION 
     With continuing reference to the drawing wherein reference numerals identify parts hereafter similarly identified, numerals  1  and  2  indicate respectively an adult, preferably knowledgeable about autism, and an autistic person. 
     An area at  3  could be a park, yard, trail, etc., having objects of interest about which both parties would likely comment upon or discuss. 
     A tether at  4  is a cord a few feet in length preferably provided with spaced loops  5  for varying tether length. 
     The autistic person at  2  is provided with a belt  6  to receive one end of the tether by means of a ring  7 , which may be a D-ring. A retainer  10  for the tether ring includes a fabric closure with hook and loop components  11  and  12  suitably affixed to belt  6  as by stitching  13 . Ring  7  has a segment  7 A in  FIG. 4  extending beyond the upright width of the components  11  and  12 , and is retained against movement by the action of the joined hook and loop components. Suitable closure material is marketed under the trademark VELCRO by the 3M Corporation. 
     If desired a lock may be provided to prevent separation of ring  7  from retainer  10 . Grommets at  14  in each component  11  and  12  are in alignment to receive the lock such as a carabiner  25 . 
     The travel of ring  7  between retainer components and toward separation is in response to tensioning of tether  4 , which is audible and indicates to the child that separation with the adult may occur. Assuming the relationship is favorable, the child will likely attempt to prevent separation and retain the side by side relationship. 
     Tether  4  terminates at its remaining end in attachment to a ring  15 , as by a carabiner  16 , to the adult&#39;s belt at  17 . A retainer  18  includes hook and loop components at  19  and  20  stitched at  21  to belt  17 . 
     In use, the belts are applied to the parties with the rings disposed toward one another with the tether being inconspicuous. The adult will initiate a conversation based on observations made during their walk. The foregoing is a very brief description of the tethers use with but one technique provided as an example. 
     A secondary or optional retainer at  22  includes fabric closure components  23  and  24  respectively on adult belt segments  17 - 17 A. Ring  15 , in response to periodic tensioning of tether  4 , must travel the length of closure components  23  and  24  for release. 
     While I have shown but a few embodiments of the tether, it will be apparent to those skilled in the art that the invention may be embodied still otherwise without departing from the spirit and scope of the claimed invention.
